To improve the security of AOMDV(Ad Hoc On-demand Multi-path Distance Vector) in WMN,this paper introduces the trust model and transition probability algorithm in AOMDV.The trust model maintains a reputation table in each node.Before routing setup,the source node will verify the trust degree of each node,which will be isolated if its degree is lower than the limited value.In order to reduce the possibility of the interception as well as to improve the security of AOMDV,transition probability is used to transmit data which disperses randomly on certain routing paths.Simulation results indicate that this improved protocol has a better packet delivery fraction and lower interception rate in WMN including malicious nodes.
