Efficient Power Consumption MAC Protocol in MANET

Mobile Ad-hoc Network (MANET) is a self configuring infrastructure-less network of mobile devices connected by wireless They have undergone rapid growth in the past several years because of their application in military and rescue service, disaster recovery operations, mobile conferencing and many other applications. 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. It saves considerable amount of power and achieves the performance matching with that of IEEE 802.11.
