Securely Deliver Data by Multi-path Routing Scheme in Wireless Mesh Networks

Wireless Mesh Networks with static Transit Access Points (TAPs) have many advantages to connect different kinds of networks. While Mobile Ad hoc Networks still have many challenges to improve because of dynamic topology and security vulnerabilities, WMNs are the best solution for wireless communication recently. To utilize the characteristics of WMN's topology, in this paper, we propose an algorithm to preserve privacy for routing. This idea comes from the fact that if we can separate data traffic into more than one path, the probability to capture all traffic from intermediate node is very small. It means it is very difficult to launch traffic analysis attacks because of traffic confidentiality. In addition, to hide securely the real source and destination addresses a new technique is proposed along with an Adaptive Key Agreement Scheme. We apply Information Entropy to model our routing traffic and highlight the robustness of the algorithm. We also present a detail traffic evaluation observed from neighboring nodes to show the availability of our proposal in term of robustness, loop free and computational overhead.
