Abstract
Disclosed are a clustering and routing method and system for a wireless sensor network. The method includes: constructing an initial MECPT; constructing cluster trees and updating MECPT; calculating clustering competition coefficients of existing cluster heads relative to nodes other than a base station; determining whether the clustering competition coefficients are all −∞; if yes, enabling non-clustered nodes to communicate with the base station following paths in the initial MECPT, and selecting child nodes of the base station in the initial MECPT as relay nodes; calculating weights about energy consumption of communication between the cluster heads and the relay nodes to get communication paths between nodes and the base station; or if no, clustering nodes based on the clustering competition coefficients, and updating the MECPT and cluster trees to which the nodes are added by an iteration process.
