A faired quality of service assured MAC protocol for Mobile Adhoc Network

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 Ad hoc 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. This paper proposes a new MAC protocol which is based on IEEE 802.11 will address the QoS, fairness and multihop capability. Simulation was carried out to support quality of service from simulation it is observed that high prioritized traffics have larger throughput and transmission capability as compared to the low prioritized traffics.
