An FSM-Based Automatic Detection in AODV for Ad Hoc Network

Ad Hoc network is brittle and vulnerable because of its special characteristics: dynamic topology, multi-hop wireless communication, and restricted resources. Attacks emerge endlessly aiming at the routing protocols and the network. First, we analyze the security goals and threats in the paper. And then a neighbor sensor election method, a competition mechanism, is described. Neighbor sensors cooperate to detect the attacks in AODV. Finally, we propose an FSM-based intrusion detection diagram for AODV to present current routing states and detecting attacks states.
