Abstract: Owing to the characteristics of rapid deployment and flexible configuration, Mobile Ad Hoc Networks (MANETs) have many applications in civilian environment, law enforcement, military arena, etc. Among these applications, data packets have to disseminate from nodes to nodes hop by hop. To facilitate these applications with much traffic among nodes, the crucial operation of MANET is routing. This paper investigates the chance to enhance the performance of routing protocol by modifying the Media Access Control (MAC) protocol. The basic idea is to increase the transmission chance for those nodes that want to relay data. Through exhaust simulation on ns-2, our novel MAC protocol enhances the on-demand routing protocols more than that of the IEEE 802.11 Distributed Coordination Function (DCF) in various system parameters.
Keywords: MAC protocol; medium access control; BEB; binary exponential back-off; routing; MANETs; mobile ad hoc networks; mobile networks; routing protocols; simulation.
