SIMULATION OF LOW POWER MAC PROTOCOLS FOR WIRELESS SENSOR NETWORKS

摘要

Wireless sensor networks have very different requirements than wireless LANs. The throughput and fairness requirements are left behind the low power-consumption. Novel MAC protocols that reduce the energy spent in listening to an idle medium or in overhearing are needed. This paper presents a simulation model of a radio layer suited for the evaluation of such low power protocols. The model of a proposed low power MAC layer is described as well. Simulation results are presented and compared with theoretical expressions.
