Discovery and Verification of Neighbor Positions in Mobile Ad Hoc Networks

ABSTRACT:

                      In mobile ad hoc network, Position aided routing protocols can offer a significant performance increase over traditional ad hoc routing protocols. These routing protocols use geographical information to make forwarding decisions, resulting in a significant reduction in the number of routing messages. However, current position aided routing protocols were not designed for use in high-risk environments, as position information is broadcasted in the clear allowing anyone within range, including the enemy, to receive. We study methods for route discovery and verification of neighbors’ position information in MANET routing protocols, and ways to use the position information to enhance performance and security of MANET routing protocols. We introduce “Neighbor position verification” (NPV), a routing protocol designed to protect the network from adversary nodes by verifying the position of neighbor nodes to improve security, efficiency, and performance in MANET routing.
