摘　　要：为了减少节点的移动给基于分群的自组织网络管理带来的影响,提高节点的可控性,提出了利用节点之间链路有效的概率来定量评估群首的稳定性,并且在群首稳定程度下降时迁移管理服务的群保持方法.仿真研究表明,该方法增大了群的生存时间,减少了群的消失数量,使得自组织网络管理工作更有效、更稳定.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 dusters.
