A Cross-Layer Security Framework for Wireless Mesh Networks

Wireless mesh networks is a new type of broadband access network. It has very typical network architecture of hybrid mesh network architecture. As wireless mesh network with distributed network architecture, it is relatively fragile and vulnerable to attack. In this paper, we first analyze the characters of hybrid mesh network architecture. The security weaknesses of WMNs mainly reflected in the transmission channel, authentication, physical protection and routing protocols. On the basis of analysis of security defects of WMNs, we design a cross-layer security framework to improve the security of WMNs. At last, we interpret some key Technologies in this security Framework.
