Study on WSN´s Fault-Tolerant Topology Control Based on GA

Topology control is the heat issue in wireless sensor networks. It is of great importance for prolonging network lifetime, reducing radio interference and increasing the efficiency of routing protocols. This paper presents a GA-based k-connected fault-tolerant topology control algorithm, called FTCGA. The algorithm takes k-connected of network as constraint and node energy consumption as optimization target. The experiment results show that the algorithm can reduce redundant links effectively and ensure network connectivity, reduce the energy consumption and prolong the life cycle of WSN.
