title = "A lightweight mechanism to secure OLSR",
abstract = "Routing protocols in ad hoc networks are vulnerable to various attacks. Many solutions have been proposed to secure ad hoc routing protocols in recent research but at the price of significant traffic and processing overhead, which may be undesirable for the ad hoc networks with limited bandwidth and processing power. In this paper, we present and evaluate a lightweight mechanism to secure OLSR (Optimized Link State Routing [1]). In our approach, the mechanism of coherence check is applied to secure the link state update. To secure the neighbor establishment, we adopt the idea based on proof introduced in AD- VSIG [2]. We identify a security flaw in ADVSIG and then propose a solution to counter it. Besides, we use the hash chain technique to reduce the processing overhead of HELLO messages in the neighbor establishment. Simulation results show that our approach is both lightweight and robust without degrading significantly the performance of OLSR.",
