Comparing Energy-Saving MAC Protocols for Wireless Sensor Networks

Overview Applications for wireless sensor networks have notably different characteristics and requirements from standard WLAN applications. Low energy consumption is the most important consideration. The low message rate that is typical for sensor network applications and the relaxed latency requirements allow for significant reductions in energy consumption of the radio. This paper present a study on the energy saved by two MAC protocols optimized for wireless sensor networks, S-MAC and T-MAC, in comparison to standard CSMA/CA. It also reports on the effects of low-power listening, a physical layer optimization, in combination with these MAC protocols.
