News	Teaching	Program Committees	For Entrepreneurs	About Me

I lead the Wireless Sensors and Mobile Ad Hoc Networks (WiSe MANet) Lab. We are engaged in both theoretical and systems research. The current focus of our theoretical research is on fundamental issues of coverage, connectivity, and deployment, with emphasis on optimality, localized design, and most importantly energy-efficiency. In systems research, we are building novel systems such as AutoWitness and AutoSense. AutoWitness will help law enforcement agencies in recovering stolen objects/assets. AutoSense aims to revolutionize behavioral sciences research by enabling reliable and real time quantification of personal exposure to addictive substances and psychosocial stress as experienced by human subjects in field.

WiSe MANet Lab is looking for a second postdoctoral fellow and several motivated Ph.D. students who would either like to participate in the development of exciting new applications of wireless sensors (such as AutoWitness and AutoSense systems), or would like to make long-lasting theoretical contributions in the area of wireless sensor networks. For details, visit WiSe MANet Lab. Be sure to read our research group's philosophy before sending me an email.

News:

Three papers from WiSe MANet Lab will appear in INFOCOM 2009 (one in the main conference and two in the miniconference).

Fox13 TV News Channel Featured a story on AutoWitness. Here is a link to the TV clip.

WiSe MANet Lab is now looking for a second postdoctoral fellow. Our first postdoctoral fellow Dr. Kurt Plarre joined us in Fall 2008. He received his Ph.D. from University of Illinois at Urbana Champaign in Eletrical and Computer Engineering under the supervision of Prof. P. R. Kumar in 2006. He also completed two years of postdoctoal work at University of California at Santa Barbara prior to joining us.

Dr. Santosh Kumar has been awarded an Early Career Research Award from the College of Arts and Sciences at the University of Memphis.

Dr. Santosh Kumar has been invited to speak at the First IEEE Workshop on the Theory of Ad-Hoc and Sensor Networks (ThASN'08) in Atlanta on September 29th on the derivation of reliable density estimates.

WiSe MANet Lab sweeps University Research Forum awards in the Graduate Category. See here for details.

Dr. Prasant Mohapatra, Professor & Chair of Computer Science at the University of California, Davis visits WiSe MANet Lab. See the announcement for his Colloquium talk.

Dr. Samir R. Das, an Associate Professor in Computer Science at the Stony Brook University visits WiSe MANet Lab. See the announcement for his Colloquium talk.

Dr. Violet Syrotiuk, an Associate Professor in School of Computing and Informatics at the Arizona State University visits WiSe MANet Lab. See the announcement for her Colloquium talk.

Dr. Kumar visited Georgia Tech (10/17/2007) and Clemson University (11/9/2007) to give a talk titled "Coverage and Connectivity in Wireless Networks: the Journey from Percolation to Reliable Density Estimates". An abstract of the talk can be found here. The slides of the talk (at Clemson) can be found here.
