To solve the problem of traditional WSN, an uneven clustering multi-hop routing algorithm for power information collection (UCPC) is proposed. The algorithm uses a hierarchical network topology structure, and considers both the influence of the location and the residual energy on cluster heads routing (CHs). Triangle module operator is used to integrate the degree of location-based membership function and that of the residual energy. And parent node is decided by the fusion results. Simulation results show that UCPC effectively balances and reduces the energy consumption, and obviously prolongs the network lifetime. The routing algorithm can achieve good performance when it is applied into the information collection system.
