Tutorial 1 – T1
Morning tutorial, 23rd of September, 2008
Professor Dr. Luigi Fratta, Professor Dipartimento di Elettronica e Informazione of the Politecnico di Milano, Italy

Tutorial Title: Topology and Coverage Planning of Wireless LANs and Wireless Mesh Networks

Abstract: Regardless specific application scenarios and wireless technologies, a wise planning of the topology of wireless network is often fundamental to determine the effective provision of the required services. To this extent, planning and optimization of wireless networks is a hot topic both for academia and mobile communications providers. Commercial wireless networks can be composed of hundreds of network elements (e.g., base stations, access points, wireless mesh routers), with multiple parameters to be configured (e.g., antenna height, transmitting power, down tilt, and azimuth). Manual optimization and re-configuration are very unpractical and too expensive for current network dimensions, thus automatic planning and optimization tools are highly required.

Planning a wireless access network roughly deals with finding positions and configuration settings for network devices, while matching service requirements and further specific constraints (including budget ones). This talk will address the problem of planning the topology of multi-site WLANs and Wireless Mesh Networks. We will start off by highlighting the fundamental differences in the planning approach of these two technologies with respect to classical 2G and 3G cellular systems, and we will introduce and comment novel optimization models and solution methodologies to capture the peculiarity of the WLAN and WMN environments.

Biography: Luigi Fratta received the Doctorate in Electrical Engineering from the Politecnico di Milano, Milano, Italy, in 1966. From 1967 to 1970 he worked at the Laboratory of Electrical Communications, Politecnico di Milano. As a Research Assistant at the Department of Computer Science, University of California, Los Angeles, he participated in data network design under the ARPA project from 1970 to 1971. From November 1975 to September 1976 he was at the Computer Science Department of the IBM Thomas J. Watson Research Center, Yorktown Heights, NY, working on modeling analysis and optimization techniques for teleprocessing systems. In 1979 he was a Visiting Associate Professor in the Department of Computer Science at the University of Hawaii. In the summer of 1981 he was at the Computer Science Department, IBM Research Center, San José, CA, working on local area networks. During the summers of 1983, 1989 and 1992 he was with the Research in Distributed Processing Group, Department of Computer Science, U.C.L.A., working on fiber optic local area networks. During the summer of 1986 he was with Bell Communication Research working on metropolitan area networks. In 1994 he has been Visiting Scientist at NEC Network Research Lab, Japan. In 2000 he has been Visiting Professor at the University of Canterbury, New Zealand. Since 1980 he is a Full Professor at the Dipartimento di Elettronica e Informazione of the Politecnico di Milano. His current research interests include computer communication networks, packet switching networks, multiple access systems, modeling and performance evaluation of communication systems, local area networks, wireless cellular systems and integrated services over IP networks.

Dr. Fratta is Fellow of IEEE.
Tutorial 2 – T2
Afternoon tutorial, 23rd of September, 2008
Dr. Abduazizov Omonjon, Technical University of Information Technology, Tashkent, Uzbekistan Tutorial title: The methodology of development the tutorials on radio-technical disciplines

Abstract: Wide introduction of information-communication and computer technologies into the process of preparing the experts on radio engineering disciplines states actual the development of the programmed training electronic textbooks and the manuals reflecting a modern scientific and practical level of development by a reality of a subject matter.

The fastening of theoretical knowledge is based by performance on them virtual laboratories and computer modeling of sophisticated physical processes as development of real physical board models for studying of complex processes demands a lot of time, and often does not enable more widely to study the processes occurring at boundary and limiting modes.

Development of electronic training tutorials on radio engineering disciplines actually consists of the maintenance of separate virtual laboratory works where the basic attention will be given not to the order of fulfilling the separate work and drawing up of the report on it, and should demonstrate functional dependence of one parameters on others, at preservation without changes of other parameters and evidently shows the basic processes connected with studying a concrete theme and a issue on discipline topic.
