摘　　要：基于虚拟骨干网的概念,研究传感器网络中虚拟骨干网的节点即关键点的选取问题。提出并讨论了主动式和被动式这两种关键点选取策略,并针对几种流行的传感器网络路由协议进行了理论分析和实验比较,理论及仿真结果表明,主动式的关键点选取策略在节点规模大的条件下具有较好的性能,因此更适合传感器网络的应用。Based on the concept of virtual backbone networks,this paper researches the problem of selecting nodes of virtual backbone networks,which is named Key Node in this paper,in Sensor Networks.It brings up and discusses two kinds of the policy about Key Node selection:passive and active.This paper analyzes a few popular routing protocols in the aspect of theory and experiment.The result indicates the active selection policy has better performance when the number of node is very large,and so to Sensor Networks it is more suitable.
