In order to effectively prolong the lifetime of wireless sensor network and balance network energy consumption, a WSN clustering routing algorithm based on hybrid genetic tabu search (CRGT) is proposed. Firstly, in the stage of cluster head election, two parameters, the residual energy of nodes and the distance from nodes to Sink node, are introduced to optimize the threshold function to make the cluster head election more reasonable. Secondly, in the stage of clustering, ordinary nodes join the cluster with the lowest cost according to the cost function to balance the node energy. Finally, a hybrid genetic tabu search algorithm is introduced to select the optimal path with the least energy consumption during data transmission. The simulation results show that, compared with the other two clustering routing algorithms, CRGT algorithm effectively prolongs the network lifetime, and the energy consumption is more balanced.
