There are a lot of measures to launch DoS attacks from the physical layer to the application layer in wireless mesh networks because of its own characteristics. In order to detect the DoS attack (Denial-of-Service attack) when wireless mesh networks adopt AODV routing protocol of Ad Hoc networks, such technologies as an end-to-end authentication, utilization rate of cache memory, two pre-assumed threshold value and distributed voting are used in this paper to detect DoS attackers, which is on the basic of hierarchical topology structure.
