Extended ECDSR protocol for energy efficient MANET

MANET is a mobile ad-hoc network without base station. MANET is collection of wireless nodes which are connected to each other, but all nodes are independent. They can communicate each other via intermediate nodes or directly. As the nodes are battery operated energy saving is important issue in the MANET. Since all the nodes are battery powered, failure of one node affect the entire network. In order to increase the lifetime of the network, routing must be energy efficient. Routing protocols like DSR, ESDSR, ECDSR, AODV, TORA [13], EEAODR [12], and EPAR [4]are proposed for MANET. Design of energy efficient routing protocol is the key issue for mobile adhoc networks. ECDSR protocol selects nodes on the basis of minimum threshold energy. As ECDSR protocol has overhearing and stale route problem, which leads to packet loss and over energy consumption. In our paper we proposed the solution to address overhearing and stale route problem by suggesting modification in ECDSR protocol. MANET is used in real time critical applications. If MANET is having dense network, then for saving energy timer technique is being proposed by us in this paper. We illustrated and proved that our proposed methodology works efficiently in the line of our solution.
