Drop Rate Minimization Using MIB under Media Access Control (MAC) Layer in MANET

Wireless local area networks (WLANs) are increasingly popular because of their flexibility. This spreading of WLANs comes with an increasing use of multimedia applications. Such applications are bandwidth sensitive and require a quality of service(QoS) that guarantees high performance transmission of continuous data. EDCA 802.11e used to supporting Quality of service for real time transmission over WLANs. But EDCA 802.11e week in Multi-hop case because of hidden station effect. however monitoring is difficult in network due to every time changing topology in mobile ad-hoc network(MANET)To resolve the problem of hidden terminal in this paper we use 802.11 MAC layer protocol which use a MIB (Management information Base) technique. A Simulation experiments - using the network simulator NS-2 are carried out to compare the performance of both protocols.
