An Improved Rsa Algorithm For Wireless Localization
COMMUNICATIONS, SIGNAL PROCESSING, AND SYSTEMS, CSPS 2018, VOL II: SIGNAL PROCESSING(2020)
Abstract
Wireless localization has become a hot issue in Internet of things, but the none-line-of-sight (NLOS) propagation will degrade the performance of traditional localization algorithms. Therefore, this paper proposed an improved range scaling algorithm (RSA) in the wireless sensor networks, where we use a two-step improvement to enhance the constrained optimization model. Simulations demonstrate that the proposed algorithm outperforms the compared algorithms, and effectively suppress the localization error caused by the none-line-of-sight propagation.
