The Design of Reliable Routing Protocols in Wireless Mesh Networks

摘要

Wireless Mesh Networks provide much flexibility in establishing a network compared to existing wire networks. A higher level of security is required for a wireless environment that makes the network accessible by anyone. Compared to MANET, Wireless Mesh Networks is less portable, and have less sensitivity to electric power. This enables the adoption of a higher level of security. This study takes advantage of the PKI (Public Key Infrastructure) security algorithm to optimize a Wireless Mesh Network, so that it is applicable to a Wireless Mesh Network environment. A Pre-Shared Key, which is dynamically created and utilizes the hash function, is adopted as the routing authentication method of the mesh router and for the distribution of Keys necessary for data encryption. Each router node of a Wireless Mesh Network encrypts a random number data for electronic signature. The techniques for supervision, detection and avoidance of malicious nodes between router nodes on a Wireless Mesh Network are presented. The security technique is applied in this environment.
