摘要
Abstract
The widely used DV-Hop localization algorithm is analyzed. In view of the insufficient in the hop estimation and position calculation, BFA-HC (Bacterial Foraging Algorithm and Hop Correction) localization algorithm is proposed. The number of hops between adjacent nodes is corrected according to the threshold values of received signal strength indicator, then its average hop dis-tance of each anchor node is calculated based on the minimum mean square error criterion. Finally, the position of unknown node is calculated by bacterial foraging algorithm when it obtains Euclidean distance to three or more anchor nodes. Simulation results show that BFA-HP algorithm can greatly improve the location accuracy of the sensor network nodes under the conditions of different network sizes, different network connectivity and different proportion of anchor nodes.关键词
