一种基于误差修正的改进DV-Hop算法
Improved DV-Hop algorithm based on error compensation
摘要
Abstract
Localization of nodes is one of the key technologies for the wireless sensor networks. An error compensation based improved algorithm is proposed to deal with the problem of DV-Hop algorithm in the localization of random distributed wireless sensor networks. Based on the principle of differential GPS, the proposed algorithm improves the distance estimation based on the error of beacons in the estimation stage of DV-Hop algorithm;and a multiple beacon errors weighted method is employed to revise the distance estimation. Simulation results prove the effectiveness of the proposed algorithm.关键词
