Secure Optimized Link State Routing Protocol for Ad-Hoc Networks
The Optimized Link State Routing protocol (OLSR) has valuable features for mobile ad hoc networks such as no route discovery delay and ease of integration into existing systems, which makes it well-suited for time critical and emergency rescue applications. In OLSR, link state information is generated only by nodes elected as MPRs. Thus, optimization is achieved by minimizing the number of control messages flooded in the network. However, security, trust, and robustness are still a sizable challenge for OLSR. In this paper, the authors first highlight potential attacks, vulnerabilities, and key countermeasure points of OLSR in terms of security.
