Research of Optimizing Weighted Centroid Distance Correction Localization Algorithm Based on RSSI
Centroid Algorithm Localization is to fix position using the wireless sensor connections, which has larger error.To increase the localization accuracy, based on the fact that the centroid algorithm is comparative stable under the changing environment, and the conveniences of RSSI, a revised and improved centroid algorithm based on RSSI is proposed in this paper.Combined with the advantages of the optimized weighted centroid and the distance correction, the node position can be positioned.Extra hardware device did not need to be added in the algorithm, the simulation and analysis results show that the accuracy of the localization is improved.
