摘要
D V-hop is a typical node location algorithm in wireless network, but the location accuracy is not high and the rate of remaining nodes is too large, under the circumstances that the distribution of sensor network is uneven and the node density is relatively small. We proposed a cooperative location algorithm to improve the performance by calculating the collinear degree of candidate anchor nodes, correcting the average hop distance as well as estimating the error of node location. Simulation results show that the improved algorithm can get high location accuracy and small rate of remaining nodes than DV-Hop algorithm when the node density and the number of anchor node are equal.
