Intrusion Detection System for Power-Aware OLSR

Optimized Link State Routing (OLSR) is a standard proactive routing protocol for Wireless Sensor Network (WSN). OLSR uses two kinds of the control messages: Hello and Topology Control (TC). As these messages are un-authenticated, OLSR is prone to several attacks namely, black hole, wormhole, Gray hole etc. This paper is focused at Sleep Deprivation Torture Attack on OLSR. Sleep deprivation attack is one of the most interesting attack in layer 2 where the attacker tries to use a low energy node until all its energy is exhausted and the node goes into permanent sleep. This attack is also possible in routing level. In OLSR low energy node declare their status through willingness property of HELLO message. Using this information an attacker node can choose that low energy node deliberately and forward all traffic through that node. This leads to low energy node in a permanent sleep mode. In this paper we propose a specification based Intrusion Detection System (IDS) for that type of attack. The performance of the propose algorithm is studied by Network Simulator (NS2) and effectiveness of the propose scheme, along with a comparison with existing techniques is demonstrated.
