ADVANCED AND EFFICIENT MAC PROTOCOL FOR MOBILE AD-HOC NETWORK

Mobile Ad-hoc Network (MANET) is an autonomous system of mobile nodes connected by wireless links. The nodes are free to move about and organize themselves into a network. These nodes change position frequently. To accommodate the changing topology special routing algorithms are needed. The Media Access Control (MAC) data communication protocol sub-layer provides addressing and channel access control mechanisms that make it possible for network nodes to access common wireless channel through distributed coordination function (DCF).This work proposes a new power controlled MAC protocol based on IEEE 802.11. Network Simulator 2 (NS2) has been used for simulation. It saves considerable amount of power and achieves the performance matching with that of IEEE 802.11
