Power consumption becomes a primary issue since wireless devices are often powered by batteries. This paper presents IEE-MAC, an improved energy efficient MAC protocol designed for ieee 802.11-Based wireless Ad Hoc networks. In TEE-MAC, every node constructs a scheduling table in the distributed way by exchanging control information in ATIM window. Every node will only wake up to transmit or receive data frames and then enter doze state following the scheduling table to conserve energy consumption. Using this mechanism, IEE-MAC can eliminate the collision, overhearing, and idle listening. Moreover, IEE-MAC can adjust the size of ATIM window adaptively according to the actual traffic load in order to reduce unnecessary energy consumption without degrading the throughput of the network. Simulation results show that our protocol attains the better energy efficiency as well as throughput than other protocols in the literature.
