Since wireless medium is high demand resource the design of an efficient medium access protocol is important for Mobile Adhoc Networks. As MAC is the base layer in the protocol stack a performance gain in this layer will have significant improvement in the overall performance of the network. Since the current IEEE 802.11 MAC standard is not adaptive to the network scenario its performance is poor in terms of throughput, fairness and delay. Although several alternatives to the existing standard is proposed many of them are not satisfactorily address the key issues of keeping the simplicity of the protocol and avoiding the overhead on the nodes on duty in emergency situations where usually adhoc networks are applied.
