A Quality of Service assured & faired MAC protocol for Mobile Adhoc Network

Mobile Adhoc Network (MANET) is a collection of mobile nodes with dynamic topology. Such networks are of interest because they do not require any prior investment in fixed infrastructure. Instead, the network nodes agree to relay each other´s packets and hence act as routers and automatically form their own cooperative infrastructure. The primary responsibility of a medium access control (MAC) protocol in Ad hoc Network is the distributed arbitration for the shared channel for transmission of packets. The performance of Adhoc Network depends upon the sincerity of the MAC protocol. The MAC protocol of this type of network should be distributed, faired & free from hidden and exposed terminal problem. It should also support real-time traffic, transmission power control & be compatible with directional antennas. Researchers have proposed many MAC protocol for MANET, but none of them are simultaneously distributed, faired and support Quality of Service besides being distributed. In this paper a new MAC protocol has been proposed which supports quality of service and exhibit fairness and workable in a multihop environment.
