Our evaluation indicates that directed diffusion can achieve significant energy savings and can outperform idealized traditional schemes (e.g., omniscient

Timing-Sync Protocol for Sensor Networks

by Saurabh Ganeriwal, Ram Kumar, Mani B. Srivastava - The First ACM Conference on Embedded Networked Sensor System (SenSys , 2003
"... Wireless ad-hoc sensor networks have emerged as an interesting and important research area in the last few years. The applications envisioned for such networks require collaborative execution of a distributed task amongst a large set of sensor nodes. This is realized by exchanging messages that are ..."

Maté: A Tiny Virtual Machine for Sensor Networks

by Philip Levis, David Culler , 2002
"... Composed of tens of thousands of tiny devices with very limited resources ("motes"), sensor networks are subject to novel systems problems and constraints. The large number of motes in a sensor network means that there will often be some failing nodes; networks must be easy to repopu-late. ..."
