The Princeton ZebraNet Project: Power-Aware Computing meets Biocomplexity Research
Joint ECE/CALCM Seminar


Margaret Martonosi
Princeton University

The field of wireless sensor networks offers many interesting applications involving autonomous use of compute, sensing, and wireless communication. In this talk, I discuss the design tradeoffs that arise when applying wireless peer-to-peer networking techniques in a mobile sensor network designed for wildlife tracking. We plan to deploy a 30-node ZebraNet system at Princeton's Mpala Research Centre in central Kenya.

The ZebraNet system includes custom tracking collars (nodes) carried by animals under study across a large, wild area; the collars operate as a peer-to-peer network to deliver logged data back to researchers. The collars include global positioning system (GPS), Flash memory, wireless transceivers, and a small CPU; essentially each node is a small, wireless, computing device. Since there is no cellular service or broadcast communication covering the region where animals are studied, ad hoc, peer-to-peer routing is needed. Overall, our goal is to use the least energy, storage, and other resources necessary to maintain a reliable system with a very high 'data homing' success rate. More broadly, we believe that the domain-centric protocols and energy tradeoffs studied for ZebraNet will have general applicability in other wireless and sensor applications.


Margaret Martonosi is currently an Associate Professor at Princeton University, where she has been on the faculty in the Department of Electrical Engineering since 1994. Her research interests are in computer architecture and the hardware/software interface. When not out zebra-chasing, Martonosi and her group do research on power-efficient microarchitectures and power-adaptive systems. Martonosi earned her Ph.D. from Stanford University in 1993, and also holds a Master's degree from Stanford and a bachelor's degree with distinction from Cornell University, all in Electrical Engineering.
