WS-10-Keynote-01: IoT Security: What Are We Talking About?
The security of the so called "Internet of Things" but, more generally, the problems linked to the security of cyber physical ecosystems is receiving a lot of attention in the media as well as within the scientific community. In this talk, I will look into the new challenges present in such environments, describe existing approaches that could probably be used to better understand and protect them and finish by looking into some new paths for research.
WS-01-Keynote-01: Addressing Spectrum Scarcity through Optical Wireless Communications
Rapid increase in the use of wireless services over the last two decades has lead the problem of the radio-frequency (RF) spectrum exhaustion. More specifically, due to thisRF spectrum scarcity, additional RF bandwidth allocation, as utilized in the recent past, is not anymore a viable solution to fulfill the demand for more wireless applications and higher data rates. The talk goes first over the potential offered by optical wireless communications to relieve spectrum scarcity. It then summarizes some of the challenges that need to be surpassed before such kind of systems can be massively deployed. Finally the talk offers an overview of some of the recent results for the determination of the capacity of optical wireless channels.
WS-03-Keynote-01: Fighting Exponential Traffic Growth - Is Mobile Network Energy Efficiency a Desperate Game?
This talk starts with presenting energy efficiency in the light of historical developments, highlights energy consumption facts, and reveals the two biggest misconceptions about energy efficiency in networks. It also discusses methodologies for evaluating how green a network is and what to expect till 2020. Finally, a vision towards (near) zero power networking is sketched.
WS-04-Keynote-01: Multi-beam MIMO for Millimeter-Wave Wireless: Architectures, Prototypes, and 5G Use Cases
Millimeter-wave (mmW) technology is emerging as a key enabler for meeting the Gigabit rate and millisecond latency requirements for 5G networks. In addition to the larger (multi-GHz) bandwidths, mmW frequencies naturally enable massive MIMO operation with compact-sized high-dimensional 2D antenna arrays. However, harnessing the opportunities of mmW MIMO poses new challenges in communication theory, signal processing, antenna design, RF architecture, analog-digital interface, and baseband processing. In particular, while electronic multi-beamforming and data multiplexing is a key operational functionality, no existing systems can deliver it: conventional digital approaches suffer from a prohibitively high complexity, and the current phased array-based systems for RF beamforming are limited to single beams. I will first outline a beamspace MIMO framework for the design and analysis of 2D massive MIMO systems, and the role of beamspace channel sparsity in reducing complexity. A hybrid analog-digital transceiver architecture - continuous aperture phased (CAP) MIMO - that achieves multi-beamforming with a lens array and enables performance-complexity optimization will be highlighted. Initial theoretical and numerical results on the potential of mmW MIMO will be presented, including dense beamspace multiplexing capability and gains in capacity and power efficiency. Results from ongoing effort in CAP-MIMO prototype development for technology translation will be presented, along with an outlook for emerging Gigabit applications and 5G use cases, including backhaul, last-mile connectivity, and small-cell mobile access networks.
WS-05-Keynote-01: Technology Trends for Communications in Extreme Conditions
Over the past few decades first responders, namely police, fire department and Emergency Medical Services (EMS) have each developed privately-operated narrowband wireless services to meet their communications needs. However, recent incidents, whether natural or human made, have exposed that the incompatibility between these wireless services, as well as their limited capacity, often presents critical threats to the lives of first responders and the public in general. Thus, there is a persistent need for a unified broadband wireless solution that can support real-time collaboration and information sharing among different types of first responders. LTE presents itself as a promising candidate for such a network due to its numerous advantages such as its large geographical footprint, large bandwidth, Quality of Service (QoS) capabilities, etc. Nevertheless, there are unique requirements and challenges for broadband wireless public safety networks. The most important requirement is interoperability, which means that personnel in different agencies have to be able to communicate directly. This requirement, combined with the limited bandwidth assigned to public safety networks in North America for instance, raises multiple challenges relating to bandwidth allocation, prioritization and scheduling, spectral efficiency, and QoS achievement. Thus, in order to extend the available bandwidth, cognitive radio access can be used in conjunction with the LTE network. Another important requirement for public safety networks is the security and privacy of information, which may not be the same for all emergency agencies. Finally, network robustness is an important requirement that has to be achieved even in the case of major incidents such as natural disasters that take out part of the network. Thus the main objective of this presentation is to address all these issues of LTE interoperability, bandwidth allocation, security and privacy, and robustness, for a first responder network.
WS-06-Keynote-01: Industrial IoT with 5G
Industrial use of wireless communications is today limited to a few domains but has gained interest the last years within industrial verticals since it can reduce cost, improve flexibility and production. This keynote will exemplify the current industrial usage of wireless communications as well as its requirements, and then address the gap between current research activities in the academia and the actual need in industry, in order to enable a wide scale adoption of 5G.

WS-10-Keynote-02: Using Software Defined Relationships to Build the Internet of Things
Consumer electronics is in transition. We are shifting from creating value and defining products using electronics to creating solutions using software. Consider the smartphone: is it a telephone, or is it a gaming unit, a calendar a camera or a television? With other form factors we can mix or match parts to create a desktop computer, a television, a home control system or whatever we can imagine. Many single-use devices and classic limitations no longer exist. The Internet is central to this revolution. It is a byproduct of creating connectivity solutions using any available means. The Internet represents a fundamental change in how we build systems and in what it means to communicate. You simply click on a URL and you're "there". You don't worry about wires or reserved frequency. You can just assume that the packets will appear at the destination most of the time. Using software defined relationships as building blocks is very different from traditional hardware-based engineering. Welcome to the new world of software and the Internet. There's no dependence on providers or networks. For the IEEE these changes present an opportunity and challenge. Devices are becoming connected, opening up new frontiers as we create and share our own solutions and become less dependent on service providers. We're at the very earliest stages of an exciting new world.
WS-01-Keynote-02: Semiconductor Lasers for Gbps Visible Light and Underwater Communications
The unregulated visible light spectrum has recently been harnessed for energy-efficient, ultra-large bandwidth, and secure data transmission. For instance, the deployment of micro light-emitting diode (LED) by mLED for visible-light communications (VLC) provides a data rate of 512 Mbit/s. This considers low cost deployment for the sole function of wireless data communications, without the intention of using the micro LEDs for illumination. YAG:Ce phosphor is also combined with LEDs for full- or half-duplex communications with 10 Mbps links over ~3 m, as developed by pureLiFi. In such scenario, whereby both VLC and solid-state lighting (SSL) are simultaneously implemented, high power light-emitters, such as laser diodes, reliable phosphor for white-light generation and spectral-efficient optical modulation techniques are critical aspects that require further research and development.For advancing the high-power light-emitter architecture, we focused on the development of laser diodes as the illumination source in place of an LED. In our recent investigation, we undertook the challenge of integrating light-generation and modulation functionalities on a semiconductor. This is achieved by employing a small foot-print, low material polarization field waveguide-modulator / laser-diode (WM-LD) configuration, fabricated seamlessly on single crystal (20/2/1) semipolar GaN substrate. The gain section produces the intense coherent beam required for subsequent white-light generation, while the integrated modulator section enabled high performance light modulation. The fabricated WM-LD exhibited a large extinction ratio of 9.4 dB and a low operating voltage range of 0 to 3.5 V, leading to a high modulation efficiency of 2.68 dB/V. The modulation effect, which is resulted from the external-field-induced quantum-confined-Stark-effect (QCSE), suggests that our device was able to operate in a manner similar to other III-V materials typically used in optical telecommunications, due to the reduced inherent piezoelectric field. A -3dB bandwidth of ~1 GHz was measured in the WM-LD, and a data rate of 1 Gbit/s (limited by the detector bandwidth) was demonstrated using non-return-to-zero on-off keying (OOK) modulation.For proof of concept demonstration of VLC and SSL dual functionalities system, we also utilized the commercially available c-plane blue GaN laser diode (LD) in conjunction with a single crystal YAG:Ce phosphor. A high data rate of 2 Gbps of the unfiltered white light was achieved using an NRZ-OOK modulation scheme, with bit-error rate (BER) less than the forward error correction (FEC) limit of 3.5×10-3. The generated white light exhibited a color rendering index (CRI) of 58 and a correlated color temperature (CCT) of 4740 K. Alternately, by using spectral-efficient orthogonal frequency division multiplexing (OFDM) encoding scheme, a significantly higher data rate of 4.4 Gbps was demonstrated, for the individual red, blue and green LDs; the combination of which are suitable for RGB white light generation. In addition, by evaluating the phosphor-film preparation process, and optics-phosphor configurations, the generated white light can be systematically tuned from cool day light to neutral light, and still achieving over 4 Gbps data transmission based on OFDM. It is expected that further development in this area could lead to 100 Gbps data rate VLC-SSL system.In underwater optical wireless communications (UWOC), we took advantage of the low absorption of seawater in blue-green (400-550 nm) window of the electromagnetic spectrum. Using 520 nm green LD, we experimentally demonstrated 2.3 Gbit/s UWOC over 7 m distance using NRZ-OOK modulation scheme. By employing OFDM technique, we achieved 4.8 Gbit/s data rate over 5.4 m water channel using a 450 nm LD.
WS-03-Keynote-02: Doubly-massive MIMO Systems at mmWave Frequencies: Opportunities and Research Challenges
One of the key features of next generation wireless communication systems will be the use of frequencies in the range 10-100GHz (aka mmWave band) in densely populated indoor and outdoor scenarios. Although conventional wisdom has always considered mmWave frequencies unsuited for cellular communications, due to increased path-loss and atmospheric absorption, recent research results have shown that on distances up to one hundred meters or even more they are actually capable of providing astonishing data-rates, larger than 1 Gbps.Due to the reduced wavelength, antenna arrays with a large number of antennas can be packed in very small volumes, making thus it possible to consider, at least in principle, communication links wherein not only the base-station, but also the user device, are equipped with very large antenna arrays. We denote this configuration as a "doubly-massive" MIMO wireless link.This talk will focus on the fundamentals of doubly-massive MIMO systems at mmWave frequencies, showing the ultimate gains that they are able to achieve, but also highlighting the extraordinary research challenges (such as, e.g., the hardware complexity and the channel estimation problem), that they pose.
WS-04-Keynote-02: What mm-waves offer for 5G networks?
Large variety of unprecedented and dispersed use cases of connected society drive the research of 5th generation mobile global network technologies. Targeted >10x user capacity increase and even higher increase in user densities have turned interest to very high frequencies and bandwidth they can provide. However, it is not only the bandwidth but now it is time to scrutinize all aspects of mm-waves from technology and business point of view, not to forget various standardization and regulation standpoints. We need to identify the challenges and opportunities as well as recognize what we know and where more mmW-related research is needed. This is a challenge for all players in 5G value chain: What could be the differentiators mmWs offer for 5G networks?
WS-05-Keynote-02: Resilient Wireless Sensor Networks for Industrial Monitoring
We present, Sprouts, a modern Wireless Sensor Networks (WSN) platform that utilizes unique service-oriented sensors with an energy-aware architecture in a Zigbee-compliant network. Serviceable sensors allow for the rapid conception of a wide spectrum of applications; efficiently shortening the time gap between design and deployment. The Sprouts platform is the result of an industry related research at Queen's University, and has successfully attracted some of the biggest industrial companies in Canada including Oil & Gas mining, steel production, and Power Grid monitoring. We also describe the deployment of the Sprouts platform to monitor the health conditions of the vibration screens and shovel teeth used by Syncrude in the oil sands of Canada. Previous to WSN, wired sensing solutions have been attempted for this project, but failed to sustain integrity in the harsh conditions imposed by the environment. A complete system was developed at Queen's University Telecommunications Research Lab (TRL) and successfully realized on a miniature working lab model.
WS-06-Keynote-02: The Tactile Internet, Use Cases and 5G Enablers
The Tactile Internet will address many challenges that are facing our society in the areas of healthcare, education, manufacturing, and transportation. To achieve this, the Tactile Internet will rely on the new generation of mobile communication systems capable of providing very low round-trip latencies along with carrier grade robustness and availability. This keynote will present Nokia's view on some of the typical use cases for the Tactile Internet and its vision of 5G components and mechanisms that have the potential of providing the performances required by those use cases.
Sunday, April 3, 09:20 - 10:00
WS-10-Keynote-03: Tutorial: Mobile Edge Computing to Enable Consumer Internet of Things
Mobile Edge Computing (MEC) is a novel paradigm that extends cloud computing capabilities and services to the edge of the network. Due to its proximity to consumers, dense geographical distribution and support for high mobility, MEC platforms can provide services with reduced latency and improved QoS. Thus it is becoming an important enabler for consumer centric Internet of Things applications and services that require real time operations e.g. connected vehicles, smart road intersection management and smart grid. The talk will highlight an architecture for MEC and discuss its applicability to connected vehicles.

WS-03-Keynote-03: Energy Harvesting and Energy Cooperation towards Green and Sustainable Wireless Networks
Wireless networks composed of energy harvesting devices will introduce several transformative changes in wireless networking as we know it: energy self-sufficient, energy self-sustaining, perpetual operation; reduced use of conventional energy and accompanying carbon footprint; untethered mobility; and an ability to deploy wireless networks at hard-to-reach places such as remote rural areas, within the structures, and within the human body. Energy harvesting brings new dimensions to the wireless communication problem in the form of intermittency and randomness of available energy, which necessitates a fresh look at wireless communication protocols at the physical, medium access and networking layers. In addition, energy cooperation through wireless energy transfer enables controlled and optimized energy harvesting at the receiving end. In this talk, I will summarize recent research results on energy harvesting communication and energy cooperation in the fields of communication theory, information theory and wireless networking, and outline several open research problems.

WS-01-Invited-Talk: Coexistence of Wi-Fi and Li-Fi Toward 5G
The growth of Internet-connected and multimedia-capable mobile devices has been exponential and the challenge to cope with the increasing demand of bandwidth-intensive services is expected to continue. Existing RF wireless technologies suffer from the spectrum scarcity, however focusing on spectrum alone to grow capacity is limited and unlikely to solve the expected network congestion. A heterogeneous network (HetNet) is a promising approach to add capacity. As we spend 90% of our times indoors and 80% of the Internet traffic happens indoors, the Wi-Fi technology has been already considered to enable indoor traffic offloading from capacity-stressed licensed RF macro/small-cells. The visible light communications (VLC) or Li-Fi is an emerging technology that uses the existing lighting infrastructure to offer high-speed data transmission combined with high-quality illumination. The Li-Fi technology has the potential for being an attractive complementary to realize indoor gigabit wireless access and to off-load data from existing cellular and Wi-Fi networks. In such multi-tiered HetNet, Wi-Fi provides overshadowing coverage for improved mobility while Li-Fi provides gigabit access for stationary or quasi-static users. In an indoor situation, a coexistence of Wi-Fi and Li-Fi is expected to improve the network throughput as well as the user's quality of service.In this talk, we focus on describing the potential of a hybrid network based on the coexistence of Wi-Fi and Li-Fi. We explore existing research activity in this area and practical framework for coexistence. We also articulate current and future research challenges based on our experience in building a proof-of-concept HetNet combining Wi-Fi and Li-Fi.

WS-02-Keynote-01: Promising PHY Research Directions for 5G+ Wireless
The 5G exploratory phase is winding down as 2016 marks the beginning of the 5G standardization phase. Accordingly, it is time to reinitiate a brainstorming endeavour for the beyond-5G wireless networks (5G+ wireless). Towards that end, this talk will present some promising PHY research directions for 5G+ wireless, including but not limited to -- 1) Some recent advances in PHY research. 2) Signal constellation design: Revisiting a well-investigated concept with new enablers in novel use cases. 3) Noncoherent communications: Getting away with pilot signals. 4) Faster-than-Nyquist signaling: How fast is too fast?
WS-07-Keynote-01: Wireless Powered Communication Networks: An Overview
Wireless powered communication network (WPCN) is a new networking paradigm where the battery of wireless communication devices can be remotely replenished by means of microwave wireless power transfer (WPT) technology. WPCN eliminates the need of frequent manual battery replacement/recharging, and thus significantly improves the cost and performance over conventional battery-powered communication networks. However, the design and future application of WPCN is essentially challenged by the low WPT efficiency over long distance and the complex nature of joint wireless information and power transfer within the same network. In this talk, we will provide an overview of the key networking structures and performance enhancing techniques to build an efficient WPCN. Besides, we point out new and challenging future research directions for WPCN.
WS-08-Keynote-01: Trends, Research Activities, and Views on Future Spectrum Management
Future wireless systems require more and more throughput to satisfy users' expectations. However, most of the lower frequencies are already allocated. Measurements have shown that actual usage of the frequencies is low. Due to this reason, regulators around the world are interested in how to utilize the unused frequencies for the benefit of the society. Example solutions include databases for TV whitespace, and LSA (licensed shared access), ASA (authorized shared access). Most flexible solution would be full cognitive radio, finding autonomously unused frequencies to use for its own transmissions. The full cognitive radio solution demands high accuracy of spectrum sensing and very efficient spectrum utilization. Recently, it has been proposed that sensing accuracy and spectrum utilization can be improved by using real world measurements and statistics extracted from them. To achieve cognitive radio based spectrum utilization, new spectrum management policies need to be developed. In this keynote, trends, research activities, and views on future spectrum management around the globe are presented.
WS-09-Keynote-01: Information-theoretic Security: Old, New, and Personal Perspectives
This talk reviews old and new results in information-theoretically secure encryption, authentication, and key agreement, asking the question of their (un-)suitability for an application context. A core issue is composability; for example, if a secret key generated by a provably-secure key-agreement protocol is used in a provably-secure encryption scheme, then the combination should also be secure. But is it? Such questions are addressed, with some surprises, using the constructive cryptography framework.
WS-12-Keynote-01: Mm-Wave Communications for 5G and the Role for D2D/ M2M
5G promises to provide extreme broadband, massive connectivity and ultra-reliable/ low latency communications across multiple vertical sectors. Due to the scarcity of suitable spectrum in the sub 6GHz region, the mm-wave spectrum (loosely defined as 6-100GHz) has become very appealing to the 5G research community. The EU funded mmMAGIC project investigates the suitability of this spectrum for 5G and designs/ develops radio access architectures and schemes to meet the challenges in this spectrum. Under the multi-antenna and multi-node theme of WP5 (work package 5), we have identified 4 use cases to provide a distinct step change in user experience to the early adopters of 5G. In meeting the challenging KPIs, the D2D and M2M communications have a vital role to play. In this talk, I will highlight the envisaged roles for D2D/ M2M in the selected 5G use cases. Also I will present some early results in this domain from the technical work of WP5.
Sunday, April 3, 14:40 - 15:20
WS-02-Keynote-02: Resource Allocation in the D2D Communications
Device-to-Device (D2D) continues to hold strong promise, not only for enhancing spectrum utilization, but also for improving wireless services. To date, various efforts have been in both research and industry, with practical implementation instances now emerging. We take a multi-faceted view of resource allocation and management in Device-to-Device Communications (D2D) in different settings: whether overlaid/underlaid; and whether in-band/out-of-band. We review the problem at the heart of the matter, and discuss its tractability, the state of the art solutions, and the road ahead.
WS-07-Keynote-02: Wirelessly Powered Communications: From Theory to Practice
The advancements in microwave power transfer (MPT) over past decades have enabled wireless power transfer over long distances. The latest breakthroughs in wireless communication, namely massive MIMO, small cells and millimeter-wave communication, make wireless networks suitable platforms for implementing MPT. This can lead to the elimination of the "last wires" connecting mobile devices to the grid for recharging, thereby tackling a long-standing ICT grand challenge. Furthermore, the seamless integration between MPT and wireless communication opens a new and actively area called wirelessly powered communications (WPC). In this talk, I will discuss novel techniques that can transform WPC from theory into practice including superdirectivity transmission, analog decoupling of power and information transfers, safety aware adaptive transmission, new waveform designs and backscattering enabled multiuser MPT.
WS-08-Keynote-02: Vehicle Communications and Spectrum Allocation: State of the Art & Trends
Connected and autonomous driving are the future of Intelligent TransportSystem (ITS) and road safety, and they have never been closer to market thantoday. In fact, all big car makers have been working on enabling suchtechnologies, of which some fractions have been already deployed in somenowadays high class vehicles, such as using broadband communication to bringInternet inside the car, or relaying on stand-alone sensors to let the carpark by itself or automatically adjust the distance to the front car on thehighway. Many more life-saving and useful features will come-out in thefuture when the full versions of these emerging technologies are deployed.Connected vehicles technology, which is also a key enabler for autonomousdriving, is based on a WiFi-like short range wireless communication akavehicle to vehicle (V2V) and vehicle to infrastructure (V2I) communication.Such a technology offers a low latency communication which is necessary toenable real-time coordination among nearby vehicles and road infrastructure,which is required to enable critical-safety applications as well asautonomous driving. But it requires a dedicated radio spectrum to ensure thereliability level which is required for the safety applications, therefore aradio spectrum has to be allocated exclusively to this type ofcommunication. For example, in both Europe and US a limited spectrum hasbeen allocated around 5.9Ghz for few years to test and validate thetechnology. But still many other places around the world need to adopt sucha spectrum allocation to facilitate the deployment of the Connected Vehiclestechnology. This talk will provide an overview about Connected Vehicles and relatedinternational and local efforts as well as open challenges towards thecommercial deployment.
WS-09-Keynote-02: Lattice Codes for Wiretap Channels: A Finite Dimensional Analysis
Lattice codes are becoming a key solution to solve multiterminal coding issues. Recent results have shown that they can achieve the secrecy capacity of the Gaussian Wiretap channel. We first explain the nested coding approach. Then we give a design criterion related to the theta series of the lattice: the flatness factor. This design criterion is not easy to analyze but it can be computed for some families of lattices: modular lattices. Some examples of modular lattices will be given as well as the information leakage related to them when they are used for secrecy purpose.
WS-12-Keynote-02: Device-to-device: from 4G to future 5G
Direct Device-to-Device (D2D) functionality was introduced into the 3GPP LTE-Advanced specifications staring from Release 12 to support proximity services (also known as ProSe).Furthermore it is widely envisioned that D2D will be one of the most important technical enablers of supporting emerging application within 5G era, as shown in for example in METIS (https://www.metis2020.com). Starting fromshort explanation of the key motivations for D2D in LTE radio access technology, this talk is focused on D2D development in METIS project: D2D related use cases and scenarios, key technology components developed within METIS project and the role of D2D in METIS concept. Insight will also be provided into the future D2D development.
Sunday, April 3, 15:20 - 16:00
WS-02-Keynote-03: Resource Allocation and Cross Layer Design in 5G Wireless Networks
The proliferation of wireless multimedia applications necessitates the development of new wireless systems that can support the expected high amount of mobile data traffic in the next years. It has been adopted by the 3GPP that the future 5G cellular networks must support the 1000-fold increase in traffic demand. This requires developing new physical layer techniques, e.g. Massive MIMO and Millimeter wave (mmWave), and new network architecture. In fact, Massive MIMO systems where base stations are equipped with hundreds of antennas have been recognized as an efficient technique to increase the spectral efficiency of wireless networks. However, the increase of capacity obtained by physical layer techniques may not be enough to meet the traffic demands and a new architecture is required. 5G networks will have a heterogeneous architecture where macro cells, small cells and D2D co-exist and may cooperate between each other to enhance the performance of the network. This will certainly add additional challenges to the problems of resource allocation. In this talk, we will highlight these challenges and provide some recent results in this area. In particular, a cross layer design framework taking into the physical layer (Massive MIMO), the heterogeneous architecture and the dynamic traffic pattern will be described. The interplay between D2D and Massive MIMO will be covered as well.
WS-07-Keynote-03: Waveform Design for WPT and SWIPT
Far-field Wireless Power Transfer (WPT) and Simultaneous Wireless Information and Power Transfer (SWIPT) have attracted significant attention in the RF and communication communities. Despite the rapid progress, the problem of waveform design to enhance the output DC power of wireless energy harvester has received limited attention so far. In this talk, we bridge communication and RF design and derive novel multisine waveforms for WPT and SWIPT. The waveforms are adaptive to the channel state information and result from a posynomial/signomial maximization problem that originates from the inherent non-linearity of the wireless power channel (concatenation of the propagation channel and rectenna). They are shown through realistic simulations to provide significant gains (in terms of harvested DC power and rate-energy region) over state-of-the-art waveforms under a fixed transmit power constraint.

WS-02-Keynote-04: When Nanotechnology meets Internet of Things
The Internet of Things (IoT) is the main paradigm through which medical devices will be connected to the Internet, thereby empowering near-real-time health services and transforming a patient's physical space into a smart space. Recent developments in nanotechnology enabled designing novel applications that can be supported by nanomachines such as smart drug administration, nanoscale surgeries, and epidemic spread detection and management. This upholds health services from being near-real time health service into real-time services. In this talk, we present a glimpse on the state-of-the art of the Internet of nanothings (IoNT). We will identify the architectural requirements necessary for IoNT-based healthcare applications, and the networking requirements entailed by those applications. We will also discuss the IoNT implementation and performance evaluation issues, especially those related to deployment, communication, and co-existence with other networking paradigms. Finally, we will highlight the main challenges and opportunities of IoNT for realizing healthcare applications and services.
