Abstract: Routes in mobile ad hoc networks can be disconnected due to the movement of nodes. By this issue the transmission of data is not secure and the adversarial nodes can easily attack the other nodes. These adversarial nodes affect the performance in networks and so, it is more important to identify the neighbor node in mobile ad hoc networks. To secure data and to minimize adversary attacks, the mobile node is required to learn the discovery and neighbor’s position which is more challenging in mobile ad hoc networks. In this paper, the fully distributed Enhanced NPV (ENPV) scheme is proposed and it is robust against colluding adversaries. This ENPV protocol can prevent maximum number of adversaries attack.
