Abstract: Wireless mobile Ad hoc network is a novel wireless mobile communication network.Because of dynamic structure，wireless channel and limited resource，the nodes of mobile Ad hoc network are susceptible compromise.It is particularly vulnerable to all kinds of network attacks.In particular，every node joins in network route，so it is especial important for the security of route protocol itself.After analyzing all kinds of attacks to AODV protocol，a novel and effective intrusion detection model are presented for route protocol in wireless mobile Ad Hoc network，which combining Finite State Machine（FSM） with statistical learning method in Support Vector Machine（SVM） based on intrusion detection technology.This model can realize secure route through attacks detection of route protocol itself in wireless mobile Ad Hoc network.Simulation results in NS-2 shows this approach based on FSM and SVM method can achieve desired precision and performance and meet the security requirement of mobile Ad Hoc network.
