Future Directions in Wireless Technology: Infostations,
Sensors, Ad-Hoc Nets and the Path to Pervasive Computing
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 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 specific examples from related proof-of-concept
prototyping and network testbed development projects at WINLAB.
Short Bio
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.
