In mobile ad hoc networks (MANET), the malicious attackers may attack the location information and routing messages. Hence these information need to be protected by means of authentication, integrity and encryption. In this paper, we propose a privacy preservation and protection for cluster based geographic routing protocol in MANET. In this technique, cluster head is chosen based on node value which is estimated based on degree difference, node mobility and residual energy. The cluster consists of GPS enabled node and antenna equipped node. The cluster that contains at least one G-Node considers the remaining energy, speed of the node along with the mobility of node to select the cluster head. In order to perform privacy and anonymity protection of cluster members, the cluster head then initializes group signature scheme. Then the secured routing technique is deployed where the routing packets are protected by encryption. By simulation results, we show that the proposed technique reduces the network overhead.
