Abstract :
Energy efficiency has become one of the major considerations for protocol design in wireless networks, especially sensor networks. Carrier sense multiple access with collision avoidance (CSMA-CA) mechanisms that incorporate energy saving features have been proposed for contention-based medium access for such networks (e.g., in IEEE 802.15.4 standard). In this paper, we develop a new analytical model for the performance of an energy conserving CSMA-CA in both saturated and periodic traffic conditions. The accuracy of the throughput predicted by the analysis is confirmed via comparison with simulation.
