摘    要:针对现有的基于虚拟坐标的路由协议不能本地感知、数据传输易受阻及能量消耗不均衡等缺点,设计了一种基于中间轴的双线路由机制,利用网络的中间轴为每个节点分配虚拟坐标,并在该虚拟坐标上实施双线路由机制。用户节点可以在不知道源节点位置的情况下找到自己感兴趣的数据,而且可以在复杂环境中确保数据的发送,有效解决其他路由协议中空洞边界或公共节点的通信热点问题。通过实验,对节点负载的规范化标准偏差及高负载节点数量进行计算,结果表明,设计的方法能获得较好的负载平衡,避免网络热点产生。

关 键 词:无线传感器网络  虚拟坐标  中间轴  路由协议

Abstract:The existing virtual coordinate based routing protocol has some disadvantages, such as not local sensitive, data transmission is easily blocked and unbalanced energy consumption. Considering all the shortcomings above, this paper designed a medial axis and double ruling based routing protocol MADR, in which gave each node a based on the medial axis, and implemented double ruling scheme on the virtual coordinate system. The consumers could find the interested data without any position information of the producers. It could guarantee delivery in complex environment, effectively avoided hot spots of the hole boundary nodes or public nodes in other routing protocols. By experiments, the normalized standard deviation of node load and number of high load node was calculated. The results show that the method can achieve good load balance and avoid hot spots in network.
Keywords:wireless sensor network  virtual coordinate  medial axis  routing protocol
