T1: Radio Resource Management in Wireless Communications - Christian Hartmann (Technische Universitaet Muenchen, Germany)
Using the radio resources efficiently at the air interface is one of the keys in order to provide broadband multimedia services for the mobile user in advanced and future wireless networks. This requires dynamic Radio Resource Management (RRM) techniques, which, ideally, are capable of adapting to traffic demands and channel conditions in space and time. Within this tutorial we present methods for different phases of the RRM: * Cell assignment via Dynamic Channel Allocation/Selection (DCA) * User assignment via Packet Scheduling, and * Admission and Load Control. The tutorial provides a classification of DCA schemes into centralized and distributed schemes and into geometry based and measurement based schemes. Using example DCA schemes, achievable gains and trade-offs will be discussed with respect to different application scenarios. Based on the cell assignment, we will then discuss the user assignment, i.e. packet scheduling. We will describe and discuss an array of different schedulers. They will be compared with respect to complexity and requirements, throughput and different fairness measures. It will be shown that the performance of the different schedulers depends differently on the expected degree of user diversity and channel diversity. In order to provide Quality of Service (QoS), class based and flow based scheduling approaches will be compared with respect to performance and complexity. A discussion of admission and load control approaches with respect to different decision criteria will round off the tutorial. All together, the tutorial will focus on general methods and concepts, rather than discussing one specific system standard. However, the relevance of the presented approaches for specific wireless systems (GSM/GPRS, WLAN, UMTS/HSPA, and 4G) will be presented.

T2: Iterative Receiver Design - Henk Wymeersch (Massachusetts Institute of Technology, US)
The main goal of this tutorial is to fill a knowledge gap in the wireless communications and signal processing communities. While many students and practicing engineers are familiar with iterative processing (as in LDPC codes and MIMO detection, for instance), they still often lack the knowledge of the underlying mathematical framework. This framework will enable researchers to develop algorithms in a more rigorous and systematic fashion. In this tutorial, we will provide a rigorous, yet accessible introduction to factor graphs and how they can be used in developing iterative algorithms for estimation and detection. We emphasize the use of the factor graphs for the design of iterative receivers, with applications in decoding (turbo and LDPC codes), MIMO detection, multi-user detection, and synchronization. This tutorial is highly interactive with many examples and exercises. Topics include: digital data transmission; optimal detection and estimation; factor graphs and the sum-product algorithm; statistical inference with factor graphs; iterative receiver design; and advanced topics in distributed processing.

T3: Modeling and Mitigating Interference in Wireless Networks - Douglas Blough (Georgia Institute of Technology, US) Samir R. Das (State University of New York at Stony Brook) Paolo Santi (IIT-CNR, IT)
One of the major factors limiting traffic carrying capacity in wireless networks is multiple access interference. There is a considerable interest of the research community in understanding and analyzing such interference and developing protocols to mitigate the impact of interference. However, defining wireless interference models that are both accurate from a radio communication point of view and tractable from a protocol/algorithmic point of view is difficult, and has been a matter of considerable research effort. This tutorial will take cross-layer point of view to address this issue in the context of multihop wireless networks. The tutorial is designed to * Provide the attendees an organic view of the considerable body of literature devoted to interference modeling/measuring and interference-aware protocol design; * Provide the attendees with an "interference-awareness toolkit," i.e., with the modeling, algorithm and protocol expertise needed to effectively deal with the complex radio interference phenomenon. * Benefit junior researchers in the field of wireless networking protocols, as well as practicing engineers who need a broad-based, fundamental background. Tutorial Outline 1. Introduction and Basic Concepts. 2. Modeling interference. We will describe the basic concepts of primary and secondary interference models. Then, we will cover various secondary models, such as graph-based models, protocol and geometric models, and SINR-based (physical interference) models. 3. Measuring Interference. We will describe practical methods for measuring interference relationships between wireless nodes and links. This part of presentation will include enough details so that the attendees will be able to perform similar measurement experiments and derive interference relationships using commodity radio platforms, such as 802.11 or 802.15.4. 4. Mitigating Interference. We will describe the physical layer techniques to mitigate interference. These include the use of multiple channels, directional antennas, MIMO antennas and transmit power control. We will then provide an overview of the algorithms and protocols that use these approaches. 5. Interference-Aware Algorithms. We will describe STDMA scheduling algorithms in the link layer (with and without the interference mitigation techniques described earlier) and routing algorithms in the network layer. We will also present joint approaches. 6. Final Remark. We will conclude with pointers to open research directions.

T4: Network Coding - Muriel Medard (MIT, US) Joerg Widmer (DOCOMO Euro-Labs, DE) Frank Fitzek (Aalborg University, DK)
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. For most practical purposes, these manipulations are linear operations over elements of a finite field. 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. Among other things, network coding can be used to increase throughput and robustness as well as reduce storage requirements, delay, and energy consumption. 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). In particular, it covers practical algorithms for data gathering in sensor networks, routing in wireless mesh networks, peer-to-peer networking and content distribution, streaming applications, etc. 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. The constraints imposed by these devices in terms of available memory and computing power may differ by several orders of magnitude. As a consequence, the encoding and decoding algorithms need to be carefully adapted to the specific problem at hand. As an example, the size of the finite field for the coding operations has an impact on network coding efficiency, but also on the encoding and decoding complexity. Coding operations may be sped up substantially through the use of specialized hardware, as evidenced by the successful implementation of network coding on Graphics Processing Units (GPUs). The energy consumed by the coding operations is of particular importance on mobile devices and needs to be considered to avoid offsetting the energy gains offered by network coding.

K2: The ultimate challenge of wireless communications is to secure them
Jean-Pierre Hubaux joined the faculty of EPFL in 1990. His research activity is focused on wireless networks, with a special interest in security and cooperation issues. In 1991, he designed the first curriculum in communication systems at EPFL. He was promoted to full professor in 1996. In 1999, he defined some of the main ideas of the National Competence Center in Research named "Mobile Information and Communication Systems" (NCCR/MICS); this center (still very active nowadays) is often nicknamed "the Terminodes project". In this framework, he has notably defined, in close collaboration with his students, novel schemes for the security and cooperation in wireless networks; in particular, he has devised new techniques for key management, secure positioning, and incentives for cooperation in such networks. In 2003, he identified the security of vehicular networks as one of the main research challenges for real-world mobile ad hoc networks. In 2007, he completed a graduate textbook entitled "Security and Cooperation in Wireless Networks", with Levente Buttyan. He is co-founder and chairman of the steering committee of WiSec (the ACM Conference for Wireless Network Security).

K3: Beyond RLS: The SPARLS Algorithm
The RLS algorithm is one of the most applied algorithms in signal processing applications, in particular in wireless communications. In this presentation, we discuss SPARLS, a low complexity Recursive L_1 regularized Least Square Algorithm for identification, detection, compensation or equalization of sparse signals, and channels of interest. The SPARLS algorithm provides significant gains in performance and is orders of magnitude less complex than RLS. It is also significantly more robust. This is a joint work with Behtash Babadi and Nicholas Kolouptsidis. Bio: Vahid Tarokh worked at AT&T Labs-Research and until August 2000, where he was the head of the Department of Wireless Communications and Signal Processing. In September 2000, he joined Department of Electrical Engineering and Computer Sciences (EECS) at MIT as an associate professor. In June 2002, he joined Harvard University as a Professor of Electrical Engineering. He has taught a variety of communications, signal processing, networking, electronics and applied mathematics courses, with his research mainly focused in the same areas .

K5: Optical Wireless Communications: Current status and future directions
Indoor Optical Wireless Communications has been studied for the last few decades, but has only been widely adopted for short-range point-to-point applications. There are several new developments that may change this. RF systems are beginning to face the challenges of line of sight communications as they move to higher carrier frequencies, such as the 60GHz band, and there are some similarities between approaches being considered and those used in the optical domain. This may lead to RF and optical wireless becoming competitive alternatives, with the same coverage characteristics, but contrasting means of implementation. The rapid growth of solid-state lighting has led to the prediction that LEDs will be used for the majority of general lighting in the future. These devices can be modulated to provide both illumination and wireless optical data transmission. Such Visible Light Communications is an area of growing interest, including research and standardization activities. This presentation will review the state of the art in these areas, and outline the challenges and possibilities for future developments. Dr Dominic O'Brien is a Reader in Engineering Science at the University of Oxford, and leads the optical wireless communications group. He gained MA(1991) and PhD (1993) Degrees from the Department of Engineering at the University of Cambridge. From 1993-1995 he was a NATO fellow at the Optoelectronic Computing Systems Center at the University of Colorado. His current research is in the field of optical wireless systems, including integrated transceiver components for high-speed networks, retro-reflecting transceivers, Visible Light Communications, Optical MIMO and optical channel characterization.
