Energy efficient random cast DSR protocol with mediation device in MANET

Mobile Ad hoc networks (MANET) basically have dynamic topology, as the routing system´s list of neighboring nodes and routers changes its location from time to time. MANET´s often consumes lot of bandwidth, as the medium is shared with other nodes. MANET nodes consumes more power, even if they don´t take part in active communication. The drawback is mainly because of limitations of the technology and routing protocols available. MANET´s are vulnerable to attack as they share a wireless medium with infrastructure less backbone. The system proposes a Routing protocol in MANET which enables efficient usage of power and bandwidth in Mobile Ad-hoc networks (MANET). Randomized Overhearing techniques is proposed to reduce power consumption and enhance effective Routing in MANET. Randomized overhearing technique is used with AODV (Ad-Hoc on Demand Distance Vector)and DSR(Dynamic Source Routing) protocols to reduce the power consumed during transmission in a MANET. Minimum hop path is introduced to reduce excess bandwidth consumption. MD(Mediation Device)protocol is proposed to extend the battery life of nodes in the MANET scenario.
