An Energy-Efficient MAC Protocol for Wireless Sensor Networks

by Wei Ye, John Heidemann, Deborah Estrin , 2002
"... This paper proposes S-MAC, a medium-access control (MAC) protocol designed for wireless sensor networks. Wireless sensor networks use battery-operated computing and sensing devices. A network of these devices will collaborate for a common application such as environmental monitoring. We expect senso ..."

Telos: Enabling Ultra-Low Power Wireless Research

by Joseph Polastre , Robert Szewczyk , David Culler , 2005
"... We present Telos, an ultra low power wireless sensor module (“mote”) for research and experimentation. Telos is the latest in a line of motes developed by UC Berkeley to enable wireless sensor network (WSN) research. It is a new mote design built from scratch based on experiences with previous mote ..."

Trickle: A Self-Regulating Algorithm for Code Propagation and Maintenance in Wireless Sensor Networks

by Philip Levis, Neil Patel, David Culler, Scott Shenker - In Proceedings of the First USENIX/ACM Symposium on Networked Systems Design and Implementation (NSDI , 2004
"... We present Trickle, an algorithm for propagating and maintaining code updates in wireless sensor networks. Borrowing techniques from the epidemic/gossip, scalable multicast, and wireless broadcast literature, Trickle uses a "polite gossip" policy, where motes periodically broadcast a code ..."

A wireless sensor network for structural monitoring

by Ning Xu, Sumit Rangwala, Krishna Kant Chintalapudi, Deepak Ganesan, Alan Broad, Ramesh Govindan, Deborah Estrin - SENSYS ’04: PROCEEDINGS OF THE 2ND INTERNATIONAL , 2004
"... Structural monitoring—the collection and analysis of structural response to ambient or forced excitation–is an important application of networked embedded sensing with significant commercial potential. The first generation of sensor networks for structural monitoring are likely to be data acquisitio ..."

acquisition systems that collect data at a single node for centralized processing. In this paper, we discuss the design and evaluation of a wireless sensor network system (called Wisden) for structural data acquisition. Wisden incorporates two novel mechanisms, reliable data transport using a hybrid of end
