Abstract
An ad hoc network, a self-organizing wireless network is made up of mobile nodes, each node act as relay for providing data communication. The topology of the ad hoc networks changes often and needs large and frequent exchange of data among the network nodes for efficient routing. Existing routing protocols are distance vector method and link state routing protocols. The location information of the adhoc network nodes are broadcasted within the transmission range. The enemy can receive the location information of the nodes. Current position aided routing protocols were not designed for use in high risk environment. We have proposed a method for secured routing in adhoc network. It is a hierarchical method to solve the above problem. This method need not maintain the route information explicitly. This reduces the number of query control messages and suits well in dynamic environment. This method is better adaptive to dynamic environment than the present proactive, reactive and zone routing protocol methods (ZRP) and improves the security, efficiency and performance in ad-hoc routing.
