Specification based IDS for camouflaging wormhole attack in OLSR

Wireless sensor networks (WSN) face different security threats that disrupt the normal activities and degrade the performance of the networks. The wormhole attack is one of the most severe security attacks in WSN. In this paper, we analyze the effect of the wormhole attack in Optimized Link State routing (OLSR), which is a standard proactive routing protocol for WSN. A modified version of wormhole attack is developed in this paper, called camouflaging wormhole attack, and a corresponding specification based IDS is designed to detect and prevent this attack. Finally, Network Simulator (NS2) is used to measure the performance of the propose algorithm. The subsequent experimental results show that the efficiency of the proposed scheme.
