Effective Path Discovery Among Clusters for Secure Transmission of Data in MANET

摘要

Ad hoc networks are new paradigm of wireless communication for mobile host. Owing to vulnerable nature of mobile ad hoc network (MANET), there are numerous security threats that disturb the development of MANET. In order to overcome such threats, an efficient anonymous routing protocol for MANETs is proposed. For this, secure neighbor should be discovered. After finding the secure neighbors, neighbors are clustered to form zones. For each group of clusters, cluster head (CH) is associated. Instead of sending the route request message to every neighbor nodes, the route request message would be send only to the CH. The CH would decide which all nodes should participate in the routing. The overhead for sending messages gets reduced as the number of route request messages (RREQ) sent is minimum. Among the different paths in the clusters, the shortest path will be determined. This protocol guarantees the security, anonymity, and high reliability of an established route.
