Energy Efficient Geographical Routing Protocol with Location Awareness in Mobile AdHoc Network

A Mobile Ad hoc Network (MANET) is a kind of wireless ad-hoc network, and is a self configuring network of mobile routers (and associated hosts) connected by wireless links the union of which forms an arbitrary topology. The routers are free to move randomly and organize themselves arbitrarily, thus the network's wireless topology may change rapidly and unpredictably. Energy is a vital resource for MANET. The amount of work one can perform while mobile node is fundamentally constrained by the limited energy supplied by one’s battery. Dynamic Source Routing (DSR) protocol is one of the most well known routing algorithms for ad hoc wireless networks. DSR uses source routing, which allows packet routing to be loop free. DSR increases its efficiency by allowing nodes that are either forwarding route discovery requests or overhearing packets through having frequent listening mode to cache the routing information. This paper suggests an approach to utilize location awareness information using Geographical Routing Protocol (GRP) to improve performance of Dynamic Source routing protocols for mobile ad hoc networks. By using location awareness information, the proposed GRP maintain table after every transmission of data update its routing table for that node to sending data with smallest path in mobile ad hoc network. Our experimental results show the effectiveness of performance on sending data from updated table to conserve power and time and obtain minimum time delay, maximum throughput and minimum data drop and retransmission attempts
