摘要：
For the disadvantage which is larger positioning error, the RSSI signal strength is used to calculate the hops between the sensors which make it more close to the real network; Meanwhile, the hyperbolic method is adopted to improve the unknown node location which eliminates the cumulative error and improves the positioning accuracy. Simulation experiments show that the positioning error of improved algorithm is better than DV - Hop algorithm that reduced by 15% or so, and the best case, the positioning error decreases to 15%, meets the demand of sensor network localization accuracy.
