Energy efficient random cast DSR protocol with mediation device in MANET

Abstract

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.
