Security enhancement of AODV routing protocol in mobile ad hoc network

Mobile ad hoc Network (MANET) is a collection of network devices which are connected through the wireless links. It is used to exchange the information. Thus in order to make the communication in MANET more secure we are exploring an approach based on trust method to secure MANETs against attacks such as black hole attack, gray hole and DOS attack. The proposed approach detects malicious node by computing trust value of the node of MANET. The approach uses generation of dummy packets by the source node and send to the destination node. Problem is taken as, to develop an approach that can secure and enhance the performance of Reactive Routing Protocol family.
