Network protocols for ultra-low power wireless sensor networks

Andreas Terzis
Department of Computer Science, Johns Hopkins University

February 20th, 2008
Location Sage 3510 - 4:00 p.m. to 5:00 p.m.
Refreshments at 3:30 p.m.


In this talk I will motivate the need for ultra low power network protocols in wireless sensor networks through an environmental monitoring application we have developed. I will then present, Koala, a reliable data retrieval system designed to operate at permille (.1%) duty cycles which are essential for long term environmental monitoring networks. I will also present, Typhoon, an epidemic routing protocol designed to reliably propagate large objects to the whole network. Finally, I will argue how techniques developed for these protocols can be broadly applied in WSNs.


Andreas Terzis is an Assistant Professor in the Department of Computer Science at Johns Hopkins University. He joined the faculty in January 2003. Before coming to JHU, Andreas received his Ph.D. in computer science from UCLA in 2000. Andreas heads the Hopkins InterNetworking Research (HiNRG) Group, in which he pursues research in the broad area of wireless sensor networks and network security.
