摘要：

Topology control is an effective method that can enhance the power efficiency and fault tolerance in WSNs and the goal of it is to extend the life of the network. As a result, double cluster head-based fault-tolerant topology control algorithm for WSNs (DCHFT) is presented which takes both network life and fault tolerance into consideration. Firstly, the algorithm uses AGNES algorithm based on nodes' location for optimizing the distribution of cluster heads to divide the network into several subareas; secondly, the main cluster head and the vice cluster head which are respectively responsible for communication of clusters and the inter-cluster are elected to form a network topology according to the distance between nodes; Finally, the simulation results show that DCHFT can reduce energy consumption, prolong the network lifetime and improve the fault tolerance, compared with the typical clustering algorithm like LEACH and EEUC. © 2018 Computer Society of the Republic of China.
