Intrusion Detection Model Based on AODV State Machine in Wireless MESH Network

In order to enhances security of wireless Mesh network, establishes intrusion detection model based on the AODV state Transition, by analyzing the AODV protocol of wireless Mesh network. In this intrusion detection model, using RREQ request information of AODV protocol as the initial state, for the later arriving information, Switch state according to the State transition conditions. If the information terminate in the normal state, deal with Normally. If the information terminate in the abnormal state, Statistics the number of abnormal information. The model give an alarm, if the number of abnormal information is bigger than the threshold in period of time. We analyze intrusion detection model by simulation experiments, validating the Higher detection rate and lower false alarm rate for the three different attacks in the wireless Mesh network.
