Wireless Mesh Networks (WMNs) is considered as a promising solution for offering self-healing, self-configuring capabilities, low-cost access in broadband services. Wireless mesh networks continue to receive significant interest in an existing new technology that has application in defense, metro-area Internet access, and transient networks (e.g.: disaster recovery and conventions). In this paper, the authors review security issues, challenges, and attacks at physical layer, medium access control, and network layers wireless mesh backbone and access control in wireless mesh network. In the wireless mesh network, there are number of an issue which affects the performance and efficiency.
