Discovery of Neighbor Nodes with Protection against Adversarial Attacks in MANETs

Mobile Ad hoc Networks are configuring itself with the autonomous networks that do not require any central authority to control and coordinate the network. Neighborhood Discovery is the discovery process in that the mobile nodes or devices which are directly reachable for communication or within the transmission range. If the source and destination are within the transmission range there is no need for discovering the position of their neighbor nodes. Neighbor Discovery process can be disturbed by the adversarial nodes for harming the system and attacks on MANETs challenge the mobile infrastructure in which nodes can join and leave easily with dynamics requests without a static path of routing. For this problem, we provide a solution by introducing the Neighbor Position Discovery & Verification (NPDV) protocol for discover and verify the position of the neighbor nodes in MANET and also protect against the attacks caused by the adversarial nodes.
