T01: Signal Waveform Design for Underwater Acoustic Communications
Charalampos C. Tsimenidis, Newcastle University, UK
Bayan S. Sharif, Newcastle University, UK
Abstract: In recent years, there has been immense interest in developing underwater acoustic communication systems, most of which are related to remote control and telemetry applications. In practice, the only feasible method to achieve sub-sea communications is by means of acoustic signals. Such acoustic links are exposed to adverse physical phenomena governing acoustic wave propagation in the sea such as ambient noise, frequency-dependent attenuation, extended multi-path and Doppler spread. This tutorial will cover the design of signalling waveforms that are suitable for utilization in underwater acoustic (UA) modems. These will include PN sequences with low auto and cross-correlation properties, chirp design, in conjunction with pulse shaping and layered modulation schemes such as orthogonal frequency division multiple access (OFDM), direct sequence and multi-carrier code division multiple access (DS- and MC-CDMA). The tutorial will also address underwater channel modelling and simulation methodologies that are useful in evaluating "dry" performance of UA systems. Furthermore, the design of receiver algorithms will be considered that utilise adaptive receive arrays, carrier-phase and symbol timing recovery, Doppler compensation and multi-user detection methodologies. The tutorial is suitable for modem engineers with limited or no experience in this area to assist them in the design of UA based communication systems.

T02: Application Architectures for Machine to Machine Communications: State of the Art and Research Directions
Roch H. Glitho, Concordia University, Canada
Abstract: Machine to Machine communications (M2M for short), a key component of Internet of Things (IoT), aims at enabling interactions between devices (e.g. sensors/actuators, smart meters) with little or no human intervention. This tutorial in four parts proposes an overview of M2M with a focus on application architectures. In the first part, the standard system architectures proposed so far for M2M (e.g. ETSI M2M architecture, Wimax M2M architecture) are introduced along with the standard communications and networking technologies (IEEE 802.15.4, Zigbee, 6LoWPAN) on which they rely. The second part discusses concrete M2M application use cases, and gives insights in the application architecture related - challenges. The use cases are used to derive a comprehensive set of requirements for M2M application architectures. In the third part, the body of knowledge in application architectures is reviewed in light of the requirements. The review includes the middleware proposed so far (e.g. RESTful Web services based - middleware). It also includes the novel applications layer protocols being developed (e.g, IETF CoAP) for M2M. The strengths and weaknesses are assessed. In the fourth part we discuss novel research directions such as the use of cloud computing and 4G Evolved Packet Core (EPC) as M2M applications enablers.

Abstract: A large number of wireless sensor nodes (SNs) are used in a Wireless Sensor Network (WSN) and information from all SNs are collected at a Base Station (BS) or a sink. After introducing a SN, various characteristics of a WSN are covered in monitoring an unattended area. There is a need to learn about how regular WSN topologies can be effectively used for physically accessible areas. Results are presented on numerous advantages of using a regression polynomial. Impact of using powerful SNs on the system coverage and connectivity are also examined. Another scheme of minimizing packet traffic by collecting data using a mobile Base Station is also considered. Energy consumption throughout the area can be equalized by controlling data packet generation rate based on how far away the SNs are with respect to the BS. An innovative technique of distributing keys for shared secret key based communication in a WSN is described and various characteristics including resiliency are outlined. Monitoring of a battle-field using a WSN is also illustrated using boundary detection of a wild forest fire. Analytical model is introduced and are compared with simulation results. The need for layered sensing in secured communication is also investigated.

Abstract: The millimeter-wave band, especially spectrum in the LMDS (28-38 GHz) and unlicensed 60 GHz bands, is at the spectral frontier of high bandwidth commercial wireless communication systems. Spectrum at 60 GHz is plentiful (up to 7 GHz unlicensed spectrum is available in many countries). Several emerging wireless standards will exploit 60 GHz to provide high data rate media streaming and rapid data transfer. Designing 60 GHz wireless systems offers different challenges than millimeter wave communication systems due to differences in the channel, circuits, antennas, algorithms, and protocols. This tutorial will provide a comprehensive introduction to 60 GHz wireless communication systems. It will discuss the entire system including propagation, RF/Analog circuits, the physical layer, and the link layer. It will discuss 60 GHz in several commercial standards including IEEE 802.15.3c and IEEE 802.11ad.

Abstract: With the proliferation of smart mobile devices, a growing number of users are now accessing streaming applications while travelling in cars, buses and trains. Market forecasts suggest that by year 2015, more than 50% of the total mobile traffic will come from streaming applications. Unfortunately, under high-speed mobility and growing network heterogeneity, mobile devices are facing increased uncertainty as well as more frequent and more substantial fluctuations in available network resources. Not only it has become more difficult to predict network bandwidth, but simply adapting multimedia quality to the predicted bandwidth is also no longer adequate as frequent and drastic quality variations reduce user quality of experience. Optimization of streaming quality in mobile environments therefore has become a challenging problem, which is receiving renewed attention from both academic and industrial research. This tutorial will provide a comprehensive overview of the latest research in the broad area of mobile streaming. Topics that will be covered include, but not limited to, characterization of bandwidth variability under high-speed mobility, use of location-based bandwidth prediction in multimedia content adaptation, introduction to HTTP-based streaming, and overview of emerging standards for mobile streaming. The tutorial will conclude with open issues and future directions of research.

Abstract: The evolving femtocell networks are envisioned to provide improved capacity and coverage in next generation cellular wireless systems. Femtocell deployments pose many challenges among which radio resource management (i.e., interference management, admission control, load balancing) is the most significant one. The aim of this tutorial is to provide an extensive overview of the radio resource management problem in femtocell networks considering both CDMA (e.g., 3G) and OFDMA (e.g., LTE, WiMAX) femtocells, and the state-of-the-art research on this topic. After a brief overview of the femtocell networks, we outline the major challenges in successful deployment of femtocells in next generation cellular wireless systems. In particular, the challenges related to resource allocation, co-tier and cross-tier interference management and admission control, mobility and handoff management, auto-configuration, timing and synchronization, and security are discussed. Then we provide a comprehensive overview of the different state-of-the-art techniques for resource allocation and interference management in femtocell networks. In this context, the interference modeling approach based on the shot-noise theory is also discussed. We consider both CDMA and OFDMA femtocells and two different approaches for resource allocation and interference management in these systems are described. The requirements and challenges for admission control and load balancing in femtocell networks are then discussed, and an example method for joint admission control and load balancing is given.

T07: Inter-Vehicular Communication: Standards, Protocol Design, and Integrated Security Metrics
Falko Dressler, University of Innsbruck, Austria
Claudio Casetti, Politecnico di Torino, Italy
Abstract: This tutorial covers the most recent progress in Inter-Vehicular Communication. In a first part, we investigate the requirements on IVC ranging from traffic information systems to safety applications with real-time communication constraints. Typical IVC approaches are introduced including fully distributed as well as infrastructure-based, and centralized 3G/4G solutions. Emphasis is laid on the most recent standardization activities in the DSRC/WAVE context. We continue to discuss relevant protocols and communication principles to provide detailed information on which communication methods can be applied and how IVC protocols are developed. We study ad hoc routing approaches and their limitations to cover wide areas as well as recent geo-routing and broadcast-based data dissemination techniques. The main focus, however, will be on recently developed beaconing approaches that can easily be built upon the IEEE 802.11p protocol standard. The second part of the tutorial will focus on Secure IVC. Relying on broadcast transmissions, IVC solutions are exposed to multiple threats. Attacks are not easily prevented because of the ephemeral nature of IVC links and the constant movement of vehicles, as well as by the stringent timing requirements of IVC applications. We discuss the vulnerabilities of IVC solutions in terms of identity management, message authentication/protection/consistency, privacy protection and in-vehicle security. This overview will provide attendees with the state of the art as well as the open challenges in the field of secure IVC.

Abstract: Opportunistic communication is a simple but effective method of leveraging multiple fading realizations to make the best instantaneous use of wireless resources. This simple idea has found many manifestations, from multi-user diversity to antenna selection to relay selection. Moreover, recent developments hint that opportunistic methods may find a wider breadth than previously thought. This tutorial outlines the principles, tools, and applications of opportunistic communication, with special attention to potential future developments and research directions. The tutorial begins with a historical background and explores the classical multi-user diversity and its extensions. Various aspects of this problem, including limited feedback, will be discussed. Relay selection is another important instance of opportunistic communication. An outline of known results in relay selection will be presented and potential future directions will be discussed. The related area of MIMO antenna selection will be visited. Finally two advanced topics will be presented: first, new results will be presented that allow the extension of opportunistic communication and its analysis to network topologies that previously could not be analyzed under multiuser diversity, for example the broadcast relay channel. Second, the application of multiuser diversity in cognitive radio will be discussed.

Abstract: The impacts of Remote Wellbeing Monitoring (RWM) extend beyond basic lifestyle gains to reach serious humane and economic consequences. The upcoming IMT-Advanced or 4G technologies will empower RWM services with substantial improvements through the use of advances such as multi-carrier access techniques, MIMO, flat architectures, small cells and convergence to all-IP networks. 4G access also promises a “greener” mobile user experience. Deployment of RWM over 4G networks, however, is not without challenges. As a network service, RWM may have stringent constraints in terms of Quality of Service (QoS), reliability and security. The nature of RWM traffic is also mixed (delay-constrained data streams, high resolution images, videos, etc.), and require particular attention from service providers given that lives might be at stake. The tutorial starts with motivating RWM services, offering an up-to-date view of the industry and the market status. It then details the technical requirements of RWM in terms of overall system design, system components, and network considerations. A primer is then provided for IMT-Advanced networks, taking 3GPP’s LTE-Advanced as an example. We review technologies and advances enabling the realization of 4G access networks. Finally, an overview of the research challenges facing dense deployment of RWM services will be given.

T10: Mobile-Station and Base-Station Cooperation for Wireless Communications
LajosHanzo, University of Southampton, UK
Abstract: The limitations of MIMOs relying on co-located array-elements are highlighted and it is shown, how the single-antenna-aided cooperative mobiles may circumvent these limitations by forming MIMOs having distributed elements. This concept is also referred to a Virtual Antenna Arrays (VAA). Then the corresponding amplify-forward and decode-forward protocols as well as their hybrids are studied. Channel coding has to be specifically designed for the VAAs in order to prevent avalanche-like error-propagation. Hence sophisticated three-stage-concatenated iterative channel coding schemes are proposed and it is argued that in the absence of accurate channel information at the relays the best way forward might be to use multiple-symbol differential detection. Indeed, it is rather unrealistic to expect that an altrustically relaying handset would also accurately estimate the source-relay channel for the sake of high-integrity coherent detection. EXIT-chart-aided designs are used for creating near-capacity solutions and a range of future research directions as well as open problems are stated.

T11: Disruption/Delay Tolerant Mobile l Ad Hoc Networks
Zhensheng Zhang, Boeing, USA
Abstract: In mobile ad hoc networks, nodes are constantly in motion and/or operate on limited power. When nodes are in motion, links can be obstructed by intervening objects. To conserve power, links are shut down periodically, resulting in intermittent connectivity. Applications in intermittent connected networks must tolerate delays beyond conventional IP forwarding delays and these networks are referred to as delay/disruption tolerant networks (DTN). New protocols specifically for DTNs must be developed as existing protocols designed for the Internet do not work properly. In this tutorial, we will review different DTN architectures and different protocol stacks proposed, the Bundle Protocol (BP), the Convergence Layer (CL) protocols such as Licklider transmission protocol (LTP)-CL, TCP-CL and UDP-CL. We will also review the state of the art in routing in DTNs and categorize these routing protocols based on information used. Recent developments in erasure coding, network coding and social networks applied to DTNs are also described. New architectures for vehicular DTNs are presented. Applications of DTNs in machine to machine and off loading traffic from cellular networks are discussed. The tutorial also identifies open research issues and intends to motivate new research and development in this area.

Abstract: The tutorial provides an introduction to the rapidly growing research area of network coding. Network coding allows intermediate nodes in a network to manipulate data, for example by sending out packets that are combinations of previously received packets instead of simply forwarding them. The initial theoretical results on network coding were followed by a wealth of applications in a number of different areas that show that the theoretical insights can be translated into practical gains.
The tutorial is divided into three parts. The first part provides the participants with the theoretical tools necessary to understand the field of network coding and focuses on the underlying algebraic principles. It will also introduce distributed randomized network codes and discuss their properties. We will not assume any prior knowledge of advanced algebra or optimization. The second part of the tutorial gives an overview of the different application areas and discusses, which types of networking problems are amenable to network coding (and which aren't). Finally, we will discuss implementation aspects in real-world systems. Such systems may range from core network routers all the way down to mobile phones and tiny sensor nodes.
