Claude Shannon established the foundation for the discipline now known as "multi-user information theory" in his pioneering paper "Two-way Communication Channels" in 1961 and later Norman Abramson published his paper "The Aloha System - Another Alternative for Computer Communications" in 1970 which introduced the concept of multiple access using a shared common channel. Thereafter for more than 40 years of study, numerous elegant theories and algorithms have been developed for multiple access techniques.
In recent years, broadband wireless data networks (for instance, IEEE 802.11 Wi-Fi, IEEE 802.16 WiMAX) are driving the development of telecommunication industry and beyond 3G (B3G) wireless systems are expected to provide a variety of multimedia services in a wide range of wireless and mobile environments. To use the scarce bandwidth resource of the wireless channel, it is necessary to design channel access control techniques for a large population of users (potentially hundreds of mobile stations).
The aim of this workshop is to discuss both multi-user communications theory and multiple access techniques and standardization activities in areas related to PHY and MAC layer protocols for contemporary networks and their interactions. We intend to provide the experts from both the academic institutes and industry with an opportunity to present their art-of-the-state results and exchange the ideas on multiple access techniques and related areas.
Workshop topics of interest include, but are not limited to:
multi-user information theory;
multiple access techniques, queuing theory methods and polling systems analysis;
MAC protocols development and analysis;
PHY/MAC cross-layer techniques.

Abstract: Today, the likelihood of having coverage of multiple access networks in populated areas is high, particularly in densely populated areas. At the same time, multi-interface terminals that enable users to simultaneously utilize multiple wireless and mobile access networks are becoming more common. This creates a tremendous potential for user-experienced performance improvement and more efficient utilization of the scarce radio resources by smartly splitting traffic streams over multiple access network simultaneously.
In this talk we will discuss and analyze performance models for the optimal static and dynamic splitting of traffic streams, and show that great improvements can be realized by doing so.

Abstract: Wireless communications and networking are the key technologies to deliver basic communication services to vehicular users, for example, through the road-side base stations (RSBs). The RSBs act as gateways for data transfer between mobile users in the vehicles and other terrestrial networks. Due to the non-continuous network coverage resulting in sporadic wireless connectivity for moving vehicles, the vehicle would like to obtain an enough amount of bandwidth in order to download and cache a large amount of data within its short limited time during which the vehicle is connected to the RSB. However, when there are more than one vehicle connected to the RSB at the same time, the link bandwidth, which is a divisible resource, should be shared among vehicles. If the available bandwidth of the RSB is not enough for all vehicles, the RSB has to be able to handle this allocation problem. This kind of bandwidth allocation problem in communication networks can be solved by game-theoretic mechanisms. To solve this allocation problem, we propose a game-theoretic model. The main concept of the model is to let each vehicle compete with others in order to obtain their required amount of bandwidth. We formulate this game as an auction game where the vehicles are the bidders and the RSB is the auctioneer. At the end of the game, portions of the bandwidth are assigned to the vehicles after all of them submit their best-response bids to the RSB. From the performance study, we observe that there are several equilibrium (i.e., solutions) of this game.
Invited Talk III: Advanced Features of Quality Achievement in Next Generation 802.11 WLANs
Speaker's bio: Yevgeni Koucheryavy is an Associate Professor in the Department of Communications Engineering at the Tampere University of Technology, Finland. He received the M.Sc. degree (1997) from the State University of Telecommunications, St.Petersburg, Russia, and the PhD degree (2004) from the Tampere University of Technology, Tampere, Finland. Before joining the Tampere University of Technology, he spent five years in industry with R&D LONIIS in St.Petersburg, Russia, where he held various technical and managerial positions. Yevgeni actively participates in IST projects, in particular he chaired ESF COST 290 "Wi-QoST: Traffic and QoS Management in Wireless Multimedia Networks" ran from 2004 to 2008. Yevgeni has authored or co-authored over 60 papers in the field of advanced wired and wireless networking and teletraffic theory. He co-edited several proceedings books published in LNCS, Springer. Yevgeni serves on TPC of a number of conferences and workshops; he also serves as an editor for several international journals. His current research interests include various networking aspects in wireless/mobile/mesh and heterogeneous communications, network and services performance evaluation, and cross layer techniques.
Abstract: Similar performance of applications in wireless domain as in current fixed IP networks is a strong requirement for seamless and successful deployment of IP-based services in converged wired/wireless networks. Providing an adequate performance level and therefore Quality of Service (QoS) to the end-user is an inherent problem even in fixed IP networks. Wireless channels add their own problems on a top of that IP flaw; being different from wired networks, wireless networks typically have time-varying and non-stationary channels. Such variations result in time-varying of the available transmission bandwidth, which in turn leads to time-varying delay of packet arrivals at the application layer, especially when Automatic Repeat Request (ARQ) mechanism is employed at the data link layer.
Recently IEEE 802.11 committee became very productive and currently is about to issue a number of WLAN-related standards. As an example, 802.11n standard will provide grate transmission speeds, up to 600 Mbps; 802.11s is targeted at mesh networking; 802.11k using new Radio Resource Management (RRM) procedures will allow to select the best available access point and therefore will arrange the way the traffic is distributed over the network; 802.11r (or fast BSS transition) will assure continuous connectivity with fast and secure handoffs. Such great efforts will surely bring a brand new Next Generation WLANs to the market that, in turn, will stimulate development of new services and business cases.
However, all upcoming IEEE 802.11 standards are about real-time services support. Every standard works to offer better facilities to real-time traffic transmission, either explicitly or implicitly – QoS differentiation, fast switching, seamless handover and many other techniques are targeted on QoS parameters optimization.
The presentation discusses explicit and implicit QoS features of upcoming IEEE 802.11 standards and analyzes their impact on services. It will reveal key design issues and strategies that contribute the methodological debate surrounding the research area. Further, results from the recent own research studies to be presented and discussed.
Invited Talk IV: Resource Allocation and Scheduling in FDD Multihop Cellular Systems

Abstract: Cellular radio systems of the next generation aim to make the most out of the available radio resources in the dimensions bandwidth, time and space. The division of time into slots, frames and superframes is standard, both for TDD and FDD duplex modes. OFDMA allows the individual disposition of subchannels as a subdivision of the bandwidth but an aggregation of subcarriers. A basic resource unit is hence a brick in this two-dimensional grid. Space is important both as the location of the base station in whose surrounding the resources are used and in spatial diversity channels. These resources are the scarce good in future radio communications, because they are required proportionally to the traffic demand per area. Due to adaptive modulation and coding schemes and large ranges of possible SINR values, the required resources for a transmission may differ by a factor ten depending on the distances. In this paper we discuss the resource allocation and scheduling mission. We introduce a control system view on the topic, taking adaptive algorithms for modulation, power, subchannel usage and channel quality indication into account.
Invited Talk V: Maximizing Admissions and Throughput in Opportunistic Interference Networks
Speaker: Dr. J. R. Thomas , Information Sciences Research, College Park, MD, USA
Speaker's bio: Joseph Thomas earned a doctorate in electrical engineering from the University of Maryland following a first class honours degree in physics and a masters degree in computer science. He is currently an independent technical consultant offering expertise and advice on issues in the information sciences area ranging from multiuser wireless communications and networks through signal processing, probabilistic learning and statistical methods. He has over 15 years experience in research, development, and analysis in communication theory, systems, and networks spanning positions in corporate industry (as technical leader), government (as principal investigator of sponsored research projects) and academia (as a full-time university faculty member). Some of his recent research aims to develop practical algorithms for various aspects of control in unstructured networks. He is a member of the American Mathematical Society and a Senior Member of the IEEE and the Information Theory and Communications societies.
Abstract: Opportunistic interference networks are unstructured clusters of a few nodes (typically of the order of tens) that seek connectivity to networked infrastructure by employing an accessible node in a (wired or wireless) local area network as a gateway. This may be effected either directly or indirectly via peers acting as relays. Nodes may be admitted to such an ad hoc configuration according to the familiar collision avoidance philosophy (executed with suitable control handshake signals to circumvent the exposed and hidden node abstractions) used by the IEEE 802.11. The enforcement of orthogonal communication, however, limits throughput severely. This talk explores an alternative approach that abandons the two-state model of the channel in favor of one where nodes estimate channel gains and interference levels. Admission decisions and related power assignments are made so as to maximize the least of the sustainable additional interference levels while employing only linear signal processing at each receiver. This, in turn, maximizes the possible number of future admissions and hence network throughput subject to node energy budgets. A nontrivial generalization to the case of multiple (elastic) traffic classes, each with its own assigned priority, illustrates the application of this approach to practice.
