Paper abstract bibtex 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 sensor networks to be deployed in an ad hoc fashion, with individual nodes remaining largely inactive for long periods of time, but then becoming suddenly active when something is detected. These characteristics of sensor networks and applications motivate a MAC that is different from traditional wireless MACs such as IEEE 802.11 in almost every way: energy conservation and self-configuration are a primary goals, while per-node fairness and latency are less important. S-MAC uses three novel techniques to reduce energy consumption and support self-configuration. To reduce energy consumption in listening to an idle channel, nodes periodically sleep. Neighboring nodes form virtual clusters to auto-synchronize on sleep schedules. Inspired by PAMAS [10], S-MAC also sets the radio to sleep during transmissions of other nodes. Unlike PAMAS, it only uses in-channel signaling. Finally, S-MAC applies message passing to reduce contention latency for sensor-network applications that require store-and-forward processing as data moves through the network. We evaluate our implementation of S-MAC over a sample sensor node, the Mote, developed at University of California, Berkeley (UCB). The experiment results show that, on a source node, an 802.11-like MAC consumes 2–6 times more energy than S-MAC for traffic load of 1–10s/message.

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 sensor networks to be deployed in
an ad hoc fashion, with individual nodes remaining largely inactive
for long periods of time, but then becoming suddenly active when
something is detected. These characteristics of sensor networks and
applications motivate a MAC that is different from traditional
wireless MACs such as IEEE 802.11 in almost every way: energy
conservation and self-configuration are a primary goals, while
per-node fairness and latency are less important. S-MAC uses three

applies message passing to reduce contention latency for
sensor-network applications that require store-and-forward processing

S-MAC over a sample sensor node, the Mote, developed at University of

S-MAC for traffic load of 1--10s/message.
