Abstract: Aiming at the problem of energy hole arising from overloaded nodes and unbalanced energy consumption in wireless sensor network, evolutionary game theory is used to establish a game model of the cluster head race, and an optimal clustering algorithm based on evolutionary game for wireless sensor networks is proposed in this paper. The residual energy of nodes, data receiving energy consumption and data forwarding energy consumption are used to design the revenue function of cluster head in the evolutionary game model, and the optimal transmit power control mechanism is applied to the selection of cluster members, thereby forming a stable connected network clustering structure. The simulation results show that the algorithm balances the load of nodes and the energy of the network. It also effectively improves the premature emergence of energy holes in the network and extends the network lifetime.
