This paper proposed a clustering routing protocol for Wireless Sensor Network (WSN) under solar energy harvesting to tackle the issue of insufficient energy storage. During the clustering stage, the protocol utilizes genetic algorithm to enhance the issue that the K-Means calculation is sensitive to outliers, and designs an efficient fitness function to iteratively find the global optimal initial clustering center; This protocol dynamically update the cluster head by incorporating the node residual energy, node harvested energy and node position into the cluster head update criterion; In the data transfer stage the node sleep scheduling mechanism is introduced during the data transmission stage to balance the network energy consumption. Through simulation and correlation of LEACH, LEACH-improved and SEP protocols, the protocol actually stretch life cycle and further develop throughput of the network.
