Performance evaluation of OLSR protocol in MANET under the influence of routing attack

Mobile Ad-hoc Networks (MANET) are mobile nodes that communicate without any predefined infrastructure and are wireless in nature. This allows MANET to be easily setup in difficult geographical terrains. MANET routing protocols are standards using which communication is carried out among the mobile nodes. MANET are very vulnerable to security attacks because of their open nature. In this paper analysis is carried out on the vulnerabilities of the Optimized Link State Routing (OSLR) protocol. The link spoofing attack and routing table overflow attack have been simulated on the OSLR protocol. The severity is measured by comparing routing attacks against performance of OLSR protocol.
