Clustering routing method of micropower wireless sensor network based on energy difference

The invention provides a clustering routing method of a micropower wireless sensor network based on energy difference. The method comprises following steps of initializing network nodes; determining position distribution of each network node; initializing energy; dividing a network region into multiple clusters, wherein each cluster comprises a cluster head node, and other nodes in the cluster are member nodes; selecting the cluster head node of each cluster in a circular election mode; after a round of cluster head node selection is finished, selecting the closest cluster head nodes by non-cluster head nodes; joining in the clusters, thus being the member nodes of the clusters; and carrying out stable data transmission by each network node through taking the cluster as a unit. According to the clustering routing method of the micropower wireless sensor network based on energy difference provided by the invention, the stable life cycle of the network can be prolonged; and the energy effectiveness problem of t
