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 of protecting position information in MANET routing protocols, and ways to use the position information to enhance performance and security of MANET routing protocols. We introduce “Secure Position Aided Ad hoc Routing” (SPAAR), a routing protocol designed to use protected position information to improve security, efficiency, and performance in MANET routing.
