Abstract:

In this talk, I'll present our results obtained from analyzing WLAN users'
mobility trace data. Unlike earlier work, we profile the movement patterns
of wireless users and predict their locations, and show that each user
regularly visits a list of places called hubs (e.g., buildings) with some
probability. We also show that over a period of time (e.g., a week), a
user may repeatedly follow a mixture of mobility profiles with certain
probabilities associated with each of the profiles. Our analysis of the
mobility trace data not only validate the existence of the so-called
sociological orbits in users' movement pattern,  but also demonstrate the
advantages of exploiting them in performing hub-level location
predictions. In particular, we show that such profile based location
predictions are more precise than common statistical approaches based on
observed hub visitation frequencies alone. I'll also talk about various
kinds of traces, and potential applications of the mobility profiling.

In addition, I will present a novel architecture that utilizes integrated
cellular and ad hoc relaying (iCAR) technology as well as mobility
profiling to provide file downloading services to vehicles among other
services in an Intelligent Transportation System (ITS). I will describe an
example design optimization problem, its formulations and our initial
solutions.

Biography:

Dr. Chunming QIAO directs LANDER, which conducts cutting-edge research
work on optical networks, wireless networks, survivable networks, and
TCP/IP technologies. He has published close to 80 and more than 120 papers
in leading technical journals and conference proceedings, respectively.
His pioneering research on Optical Internet, in particular, the optical
burst switching (OBS) paradigm in 1997. Today, OBS has become a subject of
many national and international research projects, many major IEEE
conferences and several dedicated international workshops. In addition,
his work on integrated cellular and ad hoc relaying systems (iCAR)
initiated in 1999 is recognized as the harbinger for today's push towards
the convergence between heterogeneous wireless technologies, and has been
featured in Businessweek and Wireless Europe, as well as at the websites
of New Scientists and CBC. His Research has been funded by a number of
U.S. NSF grants including two prestigious ITR awards, and by Alcatel,
Fujitsu Labs, NEC Labs, Nokia Research, Nortel, Telcordia, Sprint Advanced
Technology Lab, and ITRI (in Taiwan).

Dr. QIAO have given several keynotes, tutorials and invited talks on the
above research topics at conferences and institutions including MIT
Lincoln Lab, UCLA, ISI/USC, U. Michigan, U. Toronto etc. He is on the
editorial board of several journals and magazines including IEEE/ACM
Transactions on Networking (ToN), and IEEE Communications Magazine, and
has guest-edited several IEEE Journal on Selected Areas in Communications
(JSAC) and ACM/Baltzer's Journal on Mobile Networks and Applications
Journal (MONET) issues. He has chaired and co-chaired a dozen of
international conferences and workshops, most recently, as a Vice General
Chair for IEEE Infocom 2007, and a Co-General Chair for IEEE World of
Wireless and Mobile Multimedia (WoWMoM) 2006. Currently, he's chairing the
OFC08 Networking Subcommittee, the IEEE Tech Subcommittee on Fiber and
Wireless Integration for Access/Metro Networks (which he founded), as well
as the IEEE TC on High Speed Networks.
