The invention provides a random channel-based high-density wireless sensor network clustering method, which is characterized in that a clustering thought is applied to a LoRa network, receiving channel numbers of all terminal nodes in the network are randomly generated in an initialization stage of a communication network, and probability weights of the terminal nodes are adjusted according to energy levels of the terminal nodes. On the basis of a cluster head node generation method, residual energy is added in threshold calculation to serve as a weight parameter, a node with more residual energy has a higher probability to be selected as a cluster head node, the cluster head node broadcasts information serving as a cluster head in a channel number where the cluster head node is located, and other nodes in the channel feed back a cluster network adding application to the cluster head node. Through the optimized clustering strategy, the channel congestion problem of the high-density wireless sensor network is
