Medial axis and double ruling based routing in wireless sensor network
基于中间轴的WSN双线路由机制

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.
