Distance estimating algorithm in WSN based on minimum hop routing
最小跳数路由无线传感器网络中的节点距离测量

Indirect distance measuring is a way with high performance vs. price ratio, but more work should be done to improve the measuring precision. Derived from the behavior characteristics of the wireless sensor networks based on minimum hop count routing, a distance estimating algorithm based on the minimum hop count and the routing redundancies was presented. Compared with the DV-hop algorithm, the measuring precision is improved largely by use of the routing redundancies. The analysis and simulation validate that the method is quite effective in the wireless sensor networks deployed with dense nodes.
