T1: Design & Optimization Methods for WIMAX Systems

Prof. Bayan Sharif, Newcastle University U.K. Dr. Konstantinos Ntagkounakis, Intracom Telecom, S.A.

24 November, 2007 (09:00-13:00)

Abstract:   WIMAX is predicted to be a serious competitor to existing wireless systems (WLL, LMDS, GSM, UMTS), offering an advanced air-interface and all-IP architecture, which implies more complex network design and deployment. This tutorial aims to provide a design process and generic methodology that can be applied in different WIMAX deployment scenarios. The presentation of the methodology will be structured in such way to address both industrial and academic audience. The tutorial will present design guidelines and best practice information, based on theory and instructor’s experience in actual deployments, and outline a mathematical approach of WIMAX network design, which is currently far from optimum given the technological complexity. The tutorial also aims to address ways to improve the design process for current WIMAX networks and also highlight several potential research issues.   Targeted Audience: Academics, Students who would like to be informed on WIMAX network design practice and identify research opportunities. Consultants, Engineers that are involved in radio/wireless network design or WIMAX system design Executives, Product Managers, Marketing / Pre-Sales Managers that want to acquire know-how on the requirements of designing WIMAX access for future investments on WIMAX.

T4: Security of Mobile Communications

Prof. Noureddine Boudriga, University of Carthage, Tunisia

24 November, 2007 (14:00-18:00)

Abstract:   Mobile communications offer wireless connectivity that enables mobility and computing in many different communication environments. The huge demands from social markets are driving the growing development of mobile communications more rapidly than ever before. Consequently, a large set of new advanced techniques have emerged brought up by a larger bandwidth, more powerful processing capability, and advances in computing technology. Many new services are provided, or will be provided to potential users, and delivered with high level quality by usage of GSM, 3G networks and wireless mesh networks in public, home, and corporate scenarios.   The exceptional growth in mobile and wireless communications gives rise to serious problems of security at the level of the subscriber, network operator, and service provider. The causes of such rise, typically due to the fragility of the wireless link nature, the mobility features, and the variety of the provided services, can be classified into the following six categories: a) the physical weaknesses and limitations of mobile and communications; b) the architecture limitations; c) the complexity of services; d) the user requirements; e) the contents of provided services; and f) the evolution of hacking techniques.   Many studies have addressed carefully the mobile subscriber authentication, radio-path encryption, and secure mobility, but the so-called “security of mobile communications” does no involve only these relative independent domains. It indeed needs a more systematic approach to build up a framework layout capable of allowing: 1) the risk analysis of threats and vulnerabilities of a mobile communication system; 2) the assessment of a mobile communication system in terms of provided QoS, roaming capabilities, and security; and 3) the protection of a service provided via mobile communication systems.   The major goals of this tutorial consist in five issues: 1) analyzing and discussing the security proposals made available by the mobile cellular and ad-hoc communications systems; 2) discussing the security attacks and hacking techniques; 3) discussing security policies and security practices to help better addressing the security problem; 4) discussing the role of the network operator, the service provider, and customer in securing mobile communications; and 5) analyzing the promises, requirements, and limits of service provision in terms of security needs.   Targeted Audience:   Engineers in telecommunications and information technology, graduate students, and young researchers in mobile communications and distributed systems   Outline:   The Tutorial covers three major parts of expertise:   The first part discusses the main foundations of the techniques used for hacking and infecting using viruses via mobile communications. Threats and risk analysis are discussed in this part, along with the major techniques used to provide access control, authentication, and authorization in mobile communications.   The second part discusses and analysis the mechanisms and standards implemented by the GSM, third generation, and ad-hoc networks. These networks constitute the major components of what should be called wireless open architecture. The protection mechanisms involved in these networks are assessed.   The third part of this Tutorial discusses the security issues related to the provision of services using mobile communications. Particularly, this part contains issues related to the security of wireless sensor networks, mobile e-services, and inter-system roaming and interconnecting systems.   Biography of Presenter:   Noureddine A. Boudriga received his Ph.D. in Algebraic topology from University Paris XI (France) and his Ph.D. in Computer science from University of Tunis (Tunisia). He is currently a full Professor of Telecommunications at the University of Carthage, Tunisia and the Director of the Communication Networks and Security Research Laboratory (CNAS, University of Carthage). He is the recipient of the Tunisian Presidential award in Science and Research (2004). He has served as the General Director and founder of the Tunisian National Digital Certification Agency (2000-2004). He was involved in very active research in communication networks and system security. He authored and co-authored many chapters and books on information security, security of mobiles networks, and communication networks. He published over 200 refereed journal and conference papers. Prof. Boudriga is currently the President of the Tunisia Scientific Telecommunications Society.
