Wireless Mesh Network (WMN) is an ad-hoc network with a fixed network infrastructure (see an example in figure 1). The physical structure of a WMN includes base stations, a backbone and mobile stations. The base stations (also known as mesh routers or mesh points) are static wireless nodes, forming the network infrastructure and providing wireless network access to the mobile stations. The back...

Wireless mesh network can increase service coverage by low-cost multiple-paths between a source and a destination. But because of the wireless nature, wireless mesh network is vulnerable to diversified threats. Especially attacks by malicious nodes can decrease the performance or ravage the network. Many protocols, based on Public Key Infrastructure (PKI), have been proposed to ensure security ...
