Abstract: To alleviate the influence of the node mobility on the self-organized network management based on clustering, a method for cluster maintenance is proposed. By periodically calculating the link availability between a cluster head and its agents, the stability of the cluster head is quantitatively measured, and the network management service is migrated from an unstable cluster head whose stability is below a specific threshold value to a stable node in the cluster. The simulation results show that, our method makes the network management more efficient by increasing the cluster lifetime and decreasing the number of the disappeared clusters.

Key words: self-organized network management, cluster, cluster maintenance
