Washington State University

Audience: The tutorial is intended for practicing engineers in the networking and communications area. It is also very suitable for beginning graduate students with interests in wireless communication, networking, and mobile computing. Prior exposure to fundamentals of networking and wireless communication is a plus though not essential.

Course Description: Tremendous technological advances have been made in the development of lowcost sensor devices equipped with wireless network interfaces. The sensors monitor various types of information such as temperature, pressure, chemicals, etc. and/or transmit voice and video data. The design of largescale sensor networks interconnecting several hundred to a few thousand sensor nodes has attracted recent research attention. Such sensor networks may be used for applications spanning several domains including military, medical, industrial, and home networks. The purpose of the tutorial is to present a comprehensive introduction to wireless sensor networks - basic concepts, challenges, recent research, and further possibilities. The topics covered will be based on fundamental concepts and up-to-date material in the literature, as listed below: 1) Introduction to wireless sensor networks and evolution of protocols for sensor networks, 2) Multiple Access Protocols, 3) Routing Protocols, 4) Energy-efficient protocol design, 5) Data querying, dissemination and fusion, 6) Security, 7) Testbeds and application scenarios, and 8) Summary: Future directions and unsolved problems in this research area.

Lecturer: Dr. Krishna Sivalingam received his Ph.D. and M.S. degrees in Computer Science from State University of New York at Buffalo in 1994 and 1990 respectively; and the B.E. degree in Computer Science and Engineering in 1988 from Anna University, Madras, India. He is currently an Associate Professor in the School of Electrical Engineering and Computer Science, at Washington State University, Pullman, where he was an Assistant Professor from 1997 to 2000. Earlier, he was an Assistant Professor at University of North Carolina Greensboro from 1994 until 1997. His research interests include wireless networks, optical wavelength division multiplexed networks, and performance evaluation. He has served as a Guest Co-Editor for a special issue of the IEEE Journal on Selected Areas in Communications on optical WDM networks. He is co-recipient of the Best Paper Award at the IEEE International Conference on Networks 2000 held in Singapore. He has published an edited book on optical WDM networks in 2000. He holds three patents in wireless networks and has published several research articles including more than twenty journal publications. He will be serving as General Co-Chair for SPIE Opticomm 2003 conference; and has served as Technical Program Co-Chair of SPIE/IEEE/ACM OptiComm conference at Boston, MA in July 2002, and as Workshop Co-Chair for Workshop on Wireless Sensor Networks and Applications (WSNA) to be held in conjunction with ACM MobiCom 2002 at Atlanta, GA in September 2002.
