Performance Evaluation of Efficient MAC in Mobile Ad Hoc Wireless Networks

Wireless media is in very much demand because of high mobility of the users and establishing ad hoc network in emergency situations, which requires the designing of an efficient and priority based MAC (Medium Access Protocol) as a resource to support MANET (Mobile Ad hoc NETworks) adequately. There are various MAC standards used in MANET. The IEEE 802.11 is one of them MAC layer standard and most frequently applied to such networks presently. The authors found that the IEEE 802.11 MAC standard is not very much suitable into wireless network scenario because its poor performance results in lower throughput, higher delay, large number of collisions and poor fair access of cannels.
