A good design of MAC protocols should realize bothminimum energy consumption as well as maximum datathroughput. IEEE 802.11 power management schemefor an ad hoc network is based on the Carrier SenseMultiple Access with Collision Avoidance (CSMA/CA)access procedure to transmit/receive their data frames.CSMA/CA may waste the scarce energy and bandwidthdue to frame collisions and lengthen the frame delay dueto waiting backoff time. In addition, IEEE 802.11 powermanagement scheme does not specify how to tune theATIM window size in a beacon interval. However, theATIM window size affects the power consumption andthroughput of a network considerably. The fixed ATIMwindow size can not always accommodate the varioustraffic conditions. To conquer these problems and to improvethe performance of networks, we propose a novelenergy efficiency MAC protocol for IEEE 802.11 networksby scheduling transmission after the ATIM windowand adjusting the ATIM window dynamically toadapt to the traffic status. Simulation results show thatour protocol attains the better energy efficiency as wellas throughput than existing protocols.
