비등방성 센서 네트워크를 위한 확률적기반 Range-Free 측위 알고리즘

Abstract

This paper presents a range-free localization algorithm to improve the localizationaccuracy of the range-free scheme in anisotropic sensor networks. The proposed algorithmestimates the distance from a normal node to an anchor by considering the possibleplacements of intermediate nodes and corresponding probabilities. We showed that theproposed algorithm outperforms against DV-Hop algorithm via MATLAB simulations.
