Dec. 6 (Monday) LT1 Tutorial Title: Cognitive Radio and Adaptive Wireless Communication Systems
Lecture Type: 3.5-hour tutorial
Today’s wireless services have come a long way since the rollout of the conventional voice-centric cellular systems. The demand for wireless access in voice and high data rate multi-media applications has been increasing. New generation wireless communication systems are aimed at accommodating this demand through better resource management and improved transmission technologies. The interest in increasing the Spectrum Access and improving the Spectrum Efficiency combined with both the introduction of Software Defined Radios and the realization of the idea that machine learning can be applied to radios has created new intriguing possibilities for wireless radio researchers. In this tutorial, we will discuss the cognitive radio, software defined radio, and adaptive radio concepts from several aspects. Cognitive radio and cognitive networks are investigated from a broad aspect of wireless communication system enhancement while giving special emphasis on better spectrum utilization. The scope will include the following:
Application of SDR in advanced communication systems
Adaptive wireless communication systems
Parameter estimation for adaptation of wireless communication systems (learning environment and other factors)
Spectrum efficiency and soft spectrum usage
Multi-dimensional spectrum awareness
Applications of cognitive radio (specifically for public safety)

LT2 Tutorial Title: Wireless MediaNets: Application Driven Next Generation Wireless IP Networks
Lecture Type: 3.5-hour tutorial
Thanks to the explosive creation of multimedia contents, the pervasive adoption of multimedia coding standards, the ubiquitous access of multimedia services, the existing best effort IP network infrastructure, originally designed with little real-time QoS requirement, has started to suffer from performance degradation on emerging multimedia networking applications. This inadequacy problem is further deepened by the prevalence of last/first-mile wireless networking, such as Wi-Fi, mobile WiMAX, and many wireless sensors and ad-hoc networks. This can be evidenced by more and more fragmentation of application driven IP-based networks, such as for power grid distribution, for networked security surveillance, intelligent transportation communication and many other sensor networks. To overcome the QoS challenges, the next generation wireless IP networks have to be architected in a top-down manner, i.e., application driven layered protocol design. More specifically, based on the application media data, compression schemes are applied, the subsequent Network, MAC and PHY layered protocols are accordingly enhanced to reach the optimal performance. This is the fundamental concept behind the design of Wireless MediaNets. In this tutorial, I will address the QoS challenges specifically encountered in video over heterogeneous wireless broadband networks, and propose several application driven wireless MediaNet solutions based on effective integration of APP and MAC/PHY layers. More specifically, the congestion control for achieving airtime fairness of video streaming to maximize the link adaptation performance of Wi-Fi, the effective wireless broadcasting over large scale distributed surveillance camera networks or vehicular ad-hoc networks, and the opportunistic multicast of scalable video live streaming over WiMAX.

LT3 Tutorial Title: An Overview of IEEE 802.16m Radio Access Technology
Lecture Type: 3.5-hour tutorial
The growing demand for mobile Internet and wireless multimedia applications has motivated development of broadband wireless access technologies in the recent years. Mobile WiMAX has enabled convergence of mobile and fixed broadband networks through a common wide area radio access technology and flexible network architecture. Since January 2007, the IEEE 802.16 Working Group has been developing a new amendment of the IEEE 802.16 standard (i.e., IEEE 802.16m) as an advanced air interface to meet and exceed the requirements of ITU-R/IMT-Advanced for 4G cellular systems. The technology has been submitted as a prominent candidate for IMT-Advanced to ITU-R/WP 5D in October 2009.
Depending on the available bandwidth and multi-antenna configuration, the next generation mobile WiMAX is shown to be capable of over-the-air data transfer rates in excess of 1 Gbps and support of a wide range of high-quality and high-capacity IP-based services and applications while maintaining full backward compatibility with the existing mobile WiMAX systems to preserve investments and continuing support for the first generation products. This tutorial describes the major technical features and functionalities of IEEE 802.16m and potentials for successful deployment of the next generation of mobile WiMAX in 2012+.
The IEEE 802.16m is designed to provide the state-of-the-art mobile broadband wireless access in the next decade and to satisfy the growing demand for advanced wireless multimedia applications and services. The standardization of IEEE 802.16m and Release 2.0 of mobile WiMAX profiles are expected to complete by 2011.
Multi-hop relay architecture, multi-carrier operation, self-configuration, advanced single-user/multi-user multi-antenna schemes and interference mitigation techniques, enhanced multicast broadcast service, increased VoIP capacity, improved cell-edge user throughput, support of vehicular speeds up to 500 km/h, etc. are among the most prominent features that would make IEEE 802.16m one of the most successful and advanced broadband wireless access systems in the next decade.

Millimeter-wave (mmWave) technologies in the 60 GHz frequency band have been receiving a lot of attention in the recent days and are seen as a solution to meet the multi-Gbps needs of numerous applications including high-quality video streaming, rapid synchronization, wireless USB and multi-Gbps wireless LANs. The unlicensed spectrum available in the 57-64 GHz band in the USA (and 3.5GHz of common spectrum available worldwide) promises sufficient capacity to handle data rates in the order of 7 Gbps in the first generation of products. Already, the IEEE 802.11, IEEE 802.15, ECMA, Wireless Gigabit Alliance (WiGig), and WirelessHD specification bodies have formed groups to promote 60 GHz products and interoperability. These advances prove the viability of the technology for mmWave wireless PAN (WPAN) and wireless LAN (WLAN) applications, but significant challenges still remain including operation in LOS and NLOS environments, antennas, beamforming, protocols and algorithms. The mmWave regime offers unprecedented bandwidths that are sure to be exploited in novel ways.
Therefore, this tutorial focuses on how to realize next generation multi-Gbps WLANs and WPANs over mmWave frequencies. The tutorial will discuss the potential and challenges associated with deploying 60 GHz radios, and will provide timely insight to the communications and networking communities of the challenges, research opportunities as well as the principles and designs that will drive multi-Gbps networks. The tutorial will cover physical, MAC and networking issues, as well as the standardization activities in this area and the applications of multi-Gbps WLANs and WPANs. Special emphasis will also be given to the open challenges in achieving multi-Gbps in mmWave frequencies. We hope this tutorial will act as a catalyst and resource for continued advancement of this area.

LT5 Tutorial Title: MIMO for 3GPP LTE-Advanced and Beyond
Lecture Type: 3.5-hour tutorial
We will start with a description of performance targets for IMT-Advanced or 3GPP LTE-Advanced, respectively, and will demonstrate that advanced MIMO is an indispensible ingredient in order to meet those targets even under perfect conditions. We will then explain the principles of MIMO modes in LTE with a focus on closed-loop schemes. The baseline in LTE is single-user MIMO, i.e. users are separated by means of OFDMA and TDMA but not by spatial separation. However, LTE includes already a very simple form of Multiuser (MU) MIMO where SDMA is possible. In the uplink this is mainly a scheduling problem. However, in the downlink the precoder has to take care of inter-user interference. Therefore, we focus on MU-MIMO for the downlink. We will explain the potential benefits of MU-MIMO over SU-MIMO and describe the solution which is included in LTE. The relatively poor performance of this solution will be demonstrated and explained mainly by the too small feedback of channel state information.
This motivates to look for better MU-MIMO solutions. We will now give an introduction to information theoretic limits in order to demonstrate the potential of MU-MIMO. We will present the principles of non-linear MU-MIMO algorithms which aim at performance close to those limits.
Finally, we will consider linear MU-MIMO. We will particularly focus on limited feedback schemes including precoder or channel vector quantization codebook design. This is motivated by the fact that the amount of feedback bits is a major restriction in commercial systems.

LT6 Tutorial Title: Biologically-inspired and Nano-scale Communication and Networking
Lecture Type: 3.5-hour tutorial
The developments in communication technologies have yielded many existing and envisioned information network architectures such as cognitive radio networks, sensor and actor networks, quantum communication networks, terrestrial next generation Internet, and InterPlaNetary Internet. However, there exist many common significant challenges to be addressed for the practical realization of these current and envisioned networking paradigms such as the increased complexity with large scale networks, their dynamic nature, resource constraints, heterogeneous architectures, absence or impracticality of centralized control and infrastructure, need for survivability, and unattended resolution of potential failures. These challenges have been successfully dealt with by Nature, which, as a result of millions of years of evolution, have yielded many biological systems and processes with intrinsic appealing characteristics such as adaptivity to varying environmental conditions, inherent resiliency to failures and damages, successful and collaborative operation on the basis of a limited set of rules and with global intelligence which is larger than superposition of individuals, self-organization, survivability, and evolvability. Inspired by these characteristics, many researchers are currently engaged in developing innovative design paradigms to address the networking challenges of existing and envisioned information systems. In this tutorial, the current state-of-the-art in bio-inspired networking is captured. The existing bio-inspired networking and communication protocols and algorithms devised by looking at biology as a source of inspiration, and by mimicking the laws and dynamics governing these systems is presented along with open research issues for the bio-inspired networking. Furthermore, the domain of bio-inspired networking is linked to the forthcoming research domain of nanonetworks, which bring a set of unique challenges. The objective of this tutorial is to provide better understanding of the potentials for bio-inspired and nano-scale networking, and to motivate research community to further explore this timely and exciting field.

ST2 Tutorial Title: Locality aware P2P delivery: the way to scale Internet Video
Lecture Type: 1.5-hour tutorial
The market of Internet video began its dramatic acceleration in 2006. The number of broad video viewers is projected to grow from 560 million in 2007 to 940 million in 2013. Even social networking, which is seeing very strong growth with Facebook and other sites, probably cannot compare to the sheer numbers of new consumers that sign on broadband video in the past 12 months. Moreover, it is predicted that the majority (99+%) of videos viewed will be ad supported or free. Thus, there exists a need to distribute large amount of video cheaply to the end users.
Exist data centers and CDN providers do not have the capacity and the cost structure to handle the surging demand of Internet video. In comparison, a peer assisted (P2P-CDN) solution use resource of the peers as they join in the service. As the demand of the system grows, the capacity of the network grows too. By building locality awareness into the peer assisted solution, we can retrieve popular content from close-by peers, thus relieve the congestion on the Internet backbone. The locality aware peer assisted solution is the only way to scale Internet Video to a worldwide audience.
The purpose of the tutorial is to examine issues associated with the successful building and deployment of an efficient and reliable locality aware peer assisted content delivery solution. We start by examining some popular P2P applications, such as BitTorrent, Skype and PPLive. The study of these P2P applications helps us to understand the design principles of P2P applications in general. We then investigate the existing Internet backbone components, such as the data centers, the CDN providers, and the Internet architecture. We will see how a P2P network may effectively compliment the data centers and CDN providers. Finally, we examine a number of tools for building an efficient and reliable P2P application, such as the overlay network, the scheduling algorithm, the erasure resilient coding, and NAT/firewall traversal, P2P economy, security issues, monitoring and debugging utilities in P2P application.

ST3 Tutorial Title: Machine-to-Machine: An Emerging Communication Paradigm
Lecture Type: 1.5-hour tutorial
An unprecedented communication paradigm, facilitating a vast gamut of applications by connecting a prior unseen number of devices, is currently gripping both industrial as well as academic communities. Referred to as machine-to-machine (M2M) communication, it is essentially composed of three key ingredients: 1) a wireless end-device, 2) an infrastructure-based or infrastructure-less wireless carrier network, and 3) the back-end server network. M2M systems bear very specific and unparalleled challenges in both research and development. Prime design drivers here are the need for virtually zero-outage, immediate-response and high-efficiency to support reliable, green, long-living and delay-constrained M2M applications. With no clear winner established so far, two orthogonal approaches have thus commenced to contend for the M2M market, i.e. 1) cellular solutions relying on wide coverage; and 2) purely embedded solutions relying on cheap deployments. The prime objective of this tutorial is therefore to acquaint an academic and industrial audience with crucial design approaches and architectural elements to facilitate a viable and efficient deployment of said networks. To this end, the tutorial is structured in the four parts. In the first part, we will discuss the cradle of M2M systems and the reasoning of their emergence; we will also discuss the peculiarities of these systems, their commercial importance and standardization approaches. In the second part, we will elaborate on cellular architectures evolving around EDGE, CDMA2000, LTE and WiMAX; we will first discuss the terminal and networking architectures of already deployed M2M systems, their advantages as well as shortcomings and we then move on how emerging technologies are envisaged to handle M2M traffic. In the third part, we will deal with embedded systems which generally deliver M2M traffic via multiple hops towards a gateway which in turn is connected to the back-end server network; we will dwell on latest preamble sampling and channel hopping MAC protocols, virtual coordinate and gradient routing protocols as well as technical details of lately standardized solutions, such as the IEEE 802.15.4e MAC and IETF 6LowPAN/RPL networking protocols. In the fourth part, we will draw a comprehensive comparison between these canonical architectures and discuss in great details the tradeoff between node performance (throughput, delay), network performance (outage, lifetime) and cost (CAPEX, OPEX). Finally, we will summarize and highlight a large set of open problems which are likely to occupy the community for years to come.
