Detour attack in OLSR
Manoj Singh Gaur, Vijay Laxmi, Manish Kumar, Rajbir Kaur · 2011
In Optimized Link State Routing (OLSR), each node collects information about the network by exchanging control messages. The information is stored or updated in various repositories maintained at each node. The information in repositories is used to further generate control messages. A node has full control over its repositories. In absence of any security mechanism, a malicious node can poison information contained in the repositories causing routing disorder attacks. In this paper, we propose a novel routing disorder attack detour attack against OLSR. In this attack, a malicious node updates its repositories with fake neighborhood information resulting in generation of incorrect control messages. The fake information forces neighboring nodes to choose the malicious node as their Multi Point Relay (MPR) node. Data packets passing through malicious node are diverted to improper routes and packets may never reach their destination. A large amount of packets sent from source to destination get dropped. In this paper, we also analyze the effects of multiple attackers on network characteristics.
