Secure Position-Based Routing Protocol for Mobile Ad hoc Networks
In large and dense mobile ad hoc networks, position-based routing protocols can offer significant performance improvement over topology-based routing protocols by using location information to make forwarding decisions. However, there are several potential security issues for the development of position based routing protocols. In this paper, the authors propose a Secure Geographic Forwarding (SGF) mechanism, which provides source authentication, neighbor authentication, and message integrity by using both the shared key and the TIK protocol. By combining SGF with the Grid Location Service (GLS), they propose a Secure Grid Location Service (SGLS) where any receiver can verify the correctness of location messages.
