Abstract:
In the main part of the talk, I will present recent results on blind estimation of transmission power of a wireless node based on received power measurements. Specifically, the setup consists of a set of monitors that measure the signal power received from the transmitter, and the goal is to utilize these measurements to estimate the transmission power in the absence of any prior knowledge of the transmitter\'s location or any statistical distribution of its power. Towards this end, we exploit spatial diversity in received-power measurements and cooperation among the multiple monitoring nodes; based on theoretical analysis we obtain the Maximum Likelihood (ML) estimate, derive fundamental geometrical
insights and show that its asymptotic optimality.
If time permits, I will also present other research activities I and my colleagues in IBM Research are involved in, particularly those related to bio-inspired design of wireless and sensor networks and network management technologies.

Presenter\'s brief history
Bong-Jun Ko received B.S. and M.S. degrees in electrical engineering from Seoul National University, Korea, and received the Ph.D. degree in electrical engineering at Columbia University, New York. He has worked as a senior member of research staff in Philips Research North America, as a research engineer at LG Electronics in Korea, and has co-founded NeoMTel, Korea.
He is currently a research staff member in IBM T. J. Watson Research Center, working in Networking Technology Area, and has research interests in modeling and design of large distributed systems and mobile and wireless networks. He is the recipient of the IEEE ICNP Best Paper Award in 2003.
