Optimized Link State Routing is a routing protocol that has been extensively studied for mobile ad-hoc networks. Link spoofing, which disturbs the routing service, is one of the critical security problems related to the OLSR protocol. Existing approaches against link spoofing attack have several drawbacks. In this paper, we propose an LT-OLSR protocol that broadcasts Hello messages to neighbors within two-hops to defend networks against link spoofing attacks. Simulation and analysis results show that the LT-OLSR protocol tolerates link spoofing attacks extensively. The contributions presented in this paper are as follows: (1) We design a mechanism to ensure the integrity of a routing table. (2) In addition, our approach against link spoofing attack is not only extensive but also compact. (3) Finally, it can be practically implemented under various types of MANET environments.
