Ant-based trusted routing algorithm for wireless mesh networks

In order to establish a trusted and secure wireless mesh network, routing protocols should not only ensure the integrity, confidentiality and authentication, but also take into consideration the fact that the application of routing strategies should not impact the performance of routing protocols to a severe extent. This paper adopts Node´s Trust as a routing parameter, and some improvements are made for the initialization and convergence rate of basic ant colony algorithm. Thereby an ant-based trusted routing algorithm for wireless mesh networks is proposed. The experimental results indicate the proposed algorithm achieves improvements in such aspects as end-to-end delay, packet delivery ratio and routing overhead compared with typical DSR protocol and AODV protocol.
