一种新的无线传感器网络分簇模型

New Clustering Model for Wireless Sensor Networks

从工业现场应用的角度对无线传感器网络进行研究,提出了一种新的双簇头分级模型。该模型在单簇头模型的基础上增加了一个冗余簇头节点,在簇头节点电池耗尽或出现故障之时,冗余簇头节点能够实时切换成簇头节点以维持簇稳定工作。介绍了双簇头分级模型的工作原理、覆盖范围和能耗管理,并且对该模型的性能进行了实验仿真,实验结论证明双簇头分级模型比之单簇头分级模型有更好的稳定性和安全性,以及长的生存时间而更适合应用于工业现场。

The paper researches on wireless sensor networks from industrial field application of view, and proposes a new hierarchical model that has two cluster heads. The model adds a new redundant cluster head that changes itself into new cluster head and maintains work of the cluster when the cluster head fails to work. The paper analyzes working principle, covered area and power management of the model and simulates it. Two cluster-heads model works better than one cluster head model in industrial field, because two cluster-heads model has not only more excellent stability and safety but longer lifetime as well.
