Future Trends in Wireless Technology and the Path to Pervasive Computing

Dipankar Raychaudhuri

Abstract

Wireless systems are evolving from today’s centrally managed cellular and WLAN services towards ad-hoc heteregeneous networks capable of supporting a broad new class of “pervasive computing” applications. We discuss some of the technical challenges associated with building pervasive systems which involve opportunistic and ad-hoc communication between embedded wireless devices, mobile users and computing services within the Internet. Selected enabling technologies for this future wireless scenario are discussed, including infostations (“cache and forward”), multi-hop radio routers, cross-layer ad hoc network protocols, content- or location-aware overlays, cognitive radio, and active RFID. The talk concludes with illustrative results from ongoing proof-of-concept prototyping projects and the ORBIT wireless network testbed at WINLAB.

Biography

Dipankar Raychaudhuri is Professor, Electrical & Computer Engineering Department and Director, WINLAB (Wireless Information Network Lab) at Rutgers University. As WINLAB’s Director, he is responsible for a cooperative industry-university research center with focus on next-generation wireless technologies. WINLAB’s current research scope includes topics such as RF/sensor devices, cooperative PHY, spectrum management, cognitive radio, ad-hoc mesh networks, future 4G/WLAN systems, wireless security and pervasive computing. He is principal investigator for the “ORBIT” open-access next-generation wireless network testbed at Rutgers, and is also a planning group member for the “GENI” future Internet project under development at NSF. He has previously held progressively responsible corporate R&D positions in the telecom/networking industry including: Chief Scientist, Iospan Wireless (2000-01), Assistant General Manager & Dept Head-Systems Architecture, NEC USA C&C Research Laboratories (1993-99) and Head, Broadband Communications Research, Sarnoff Corp (1990-92).

Dr. Raychaudhuri obtained his B.Tech (Hons) from the Indian Institute of Technology, Kharagpur in 1976 and the M.S. and Ph.D degrees from SUNY, Stony Brook in 1978, 79. He is a Fellow of the IEEE.
