a framework of secure location service for position-based ad hoc routing
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, so far security issues in position-based routing protocols has not been widely considered. In this paper, we identify several security problems of position-based routing protocols in mobile ad hoc networks. To avoid these problems, we propose the Secure Grid Location Service (SGLS), which enhances the original GLS protocol with secure features. Countermeasures employed by SGLS against feasible attacks use both a broadcast authentication protocol and a reputation system for monitoring. Simulation results showed that SGLS can detect and isolate message dropping attackers efficiently.
