Reactive routing protocols in Mobile Ad Hoc Networks (MANETs) such as Ad Hoc On-Demand Distance Vector (AODV) and Dynamic Source Routing (DSR) are vulnerable to sinkhole attack. Sinkhole attack is a route disruption attack. The malicious sinkhole nodes attempt to lure almost all the traffic by propagating false routing information and disrupting the normal operation of the network. The sinkhole nodes should be detected and isolated from the MANET as early as possible. Hence, a consistent, reliable and effective method of detecting sinkhole nodes is required. We have developed a method to detect the sinkhole nodes by observing the behaviour of the mobile nodes in the neighbourhood and isolating them from the MANET. The proposed method was simulated and the experimental analysis was carried out. The results show that the proposed method is consistent, reliable and effective in detecting and isolating the sinkhole nodes in MANET.
