Future Trends in Wireless Technology and the Path to Pervasive Computing
Dipankar Raychaudhuri WINLAB, Rutgers University


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 real-time, opportunistic and ad-hoc communication between low-power embedded wireless sensors/actuators and computing devices within the Internet. Selected enabling technologies for this pervasive computing scenario are discussed, including the infostation (wireless cache), multimodal wireless sensors, self-organizing ad-hoc network protocols, and cognitive radio. The talk concludes with some examples from related proof-of-concept prototyping projects and the ORBIT wireless network testbed under development at WINLAB.


Speaker information:

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, UWB, cognitive radio, ad-hoc mesh networks, wireless security, future 4G/WLAN systems, and pervasive computing. He is also principal investigator for the NSF-funded "ORBIT" open-access next-generation wireless network testbed now under construction at Rutgers. 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
