Wireless sensor network (WSN) has the characteristics of large-scale, low cost, low power consumption and high network invulnerability, which can meet the needs of large-scale and fast networking of intelligent distribution communication system. Because the sensor nodes in WSN of intelligent distribution network have great differences in computing power, storage space, energy and so on, in order to achieve efficient and reliable communication links, it is more appropriate to use heterogeneous nodes for WSN networking of intelligent distribution network. In this paper, the node design method, node deployment method and network routing protocol of intelligent distribution network WSN based on heterogeneous nodes are systematically studied. The transmission success rate basically meets the demand of more than 80%.
