A New Secured Routing Protocol To Minimize the Risk of Link Failure in MANET

computer Engineering

The utility and diversity of mobile ad-hoc network are increasing day to day. The quality routing is major issue in mobile ad-hoc network. Due to mobility of node and dynamic infrastructure the mobile node lost their path and communication process is failed. For the improvement of link failure prediction various protocol and algorithm are designed by various authors and scientists. In this dissertation modified the AODV routing protocol for the detection of link failure prediction. The modified protocol is called secured efficient routing protocol (SEAODV). The SEAODV protocol is based on two functions one is leader-based function and one is energy-based function. The leader-based function measures the distance of normal node and failure node. Our proposed algorithm is very efficient in compression in AODV routing protocol. For the evaluation of performance our modified protocol tested in different network scenario tested through simulations for different distributions of nodes and path and different connectivity models. Under all the evaluated scenarios, the technique demonstrates excellent detection probabilities with few failures of path during selection process. Our proposed modified scheme “SEAODV” simulate in NS-2 simulator. process we used. The evaluation of performance is measured by packet delivery ratio, normalized load, packet throughputs. Our modified scheme is compared with existing AODV and good results in compare with old method.
