Abstract Wireless sensor nodes may be spread over large areas and long distances, and require multi‐hop communications between nodes, making direct management numerous wireless sensor nodes inefficient. Hierarchical management can be adopted to control several nodes. Effectively controlling the top‐level nodes can decrease the costs of managing nodes and of the communication among them. The lower‐level nodes are controlled and organized with the higher‐level nodes. This study presents an algorithm for self‐organization mechanism of higher‐level nodes, contesting member nodes by multi‐hop to form hierarchical clusters, and applying the ‘20/80 rule’ to determine the ratio of headers to member nodes. Furthermore, the broadcast tree is constructed with the minimum number of hops. Simulation results indicate that the mechanism has a 6–22% lower cover loss than other approaches. The average delay of the minimum hop count approach is 0.22–1.57ms less than that of free hop count approach. The simulation also reveals the influence of 20/80 rule on cluster formation between sensor nodes. Copyright © 2006 John Wiley & Sons, Ltd.
