Mobile Ad-hoc Network 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). In the proposed work we will include analysis and implementation of conventional DCF protocol and proposes a new enhanced DCF protocol (EDCF) by improvements in the Binary Exponential Back-off Algorithm (BEB) and compare the performance of Enhanced DCF with conventional DCF protocol on different parameters. Keywords—Mobile Ad-hoc Network, Wireless Network, 802.11 MAC, Distributed Coordinated Function (DCF), Point Coordination Function (PCF), Binary Exponential Back-off (BEB).
