Summary

 Radio Frequency Identification (RFID) is the future of present-day
optical scanning. The promise of RFID and it’s eventual widespread
successful deployment within a commercial supply chain is predicated
on low cost, passive tags that support reliable, fast reading of tag
IDs.  In this talk, we describe some recent work aimed at enhancing
RFID components for use in creating sensor nets that support higher
data rates/throughput and/or greater ranges. The required system
`reverse engineering’ challenges to meet the above goals will be
described, along with the following accomplishments by our research
group  –

i.      Prototyping a new tag – Wireless Identification and Sensing
Platform (WiSP) –based on a programmable low power micro-controller
and a USRP based Software Defined Reader – suitable for laboratory
research/experimentation platform.
ii.     Improved (beyond Gen 2) uplink spectral efficiency via higher
order modulation and forward error correction (FEC) coding schemes
that are compatible with Gen-2 binary modulation.
iii.     A new energy aware model and estimate for achievable tag read
rate that considers tag availability (duty cycling) due to harvested
energy constraints.

 BIO

Sumit Roy (Fellow, IEEE) received the B. Tech. degree from the Indian
Institute of Technology (Kanpur) in 1983, and the M. S. and Ph. D.
degrees from the University of California (Santa Barbara), all in
Electrical Engineering in 1985 and 1988 respectively, as well as an M.
A. in Statistics and Applied Probability in 1988. Presently he is
Professor of Electrical Engineering, Univ. of Washington where his
research interests include analysis/design of wireless communication
and sensor network systems. His research areas of interests broadly
includes wireless and sensor networks, with a recent emphasis on
multi-standard wireless inter-networking and cognitive radio,  sensor
networking involving RFID technology and emergent vehicular networks.
He spent 2001-03 on academic leave at Intel Wireless Technology Lab as
a Senior Researcher engaged in systems architecture and standards
development for ultra-wideband systems (Wireless PANs) and next
generation high-speed wireless LANs. Between Jan-Jun 2008, he spent a
sabbatical at Univ. College Dublin as an SFI Isaac Walton Fellow and
was  a RAE (UK) Distinguished Visitor during July 2011.

His activities for the IEEE Communications Society (ComSoc) includes
membership of several technical and conference program committees.  He
has served as Associate Editor for IEEE Trans. Communications and IEEE
Trans. on Wireless Communications and currently serves on the
Editorial Board for  IEEE  Trans. Communications (2nd tour), IEEE
Trans. Intelligent Transportation Systems and IEEE  Trans. Smart Grid.
