Fault-Tolerant Topology Control Based on Artificial Immune Theory in WMNs.

With more and more wireless city are constructed completely, the wireless mesh network is widely applied. However, the more applications are serviced in Wireless Mesh Network(WMN), the bigger influence when there is a failure in wireless mesh network. In order to enhance the reliability of WMN, we proposed a Fault-Tolerant topology control algorithm based on Artificial Immune(FTAI). FTAI controls network topology to ensure that the client nodes can maintain k-connectivity to the mesh router nodes, as a result, the network can tolerate k-1 nodes failure. For optimizing the process, FTAI designs a secondary immunization clonal selection algorithm to accelerate the computing speed. Through the analysis of experimental results, the WMN achieved optimum performance of many aspects in the premise of network fault-tolerant. © 2013 Springer-Verlag.
