TDL: محلی سازی دو بعدی برای اهداف تلفن همراه با استفاده از سنجش فشار در شبکه های حسگر بی سیم

In this paper, we develop a novel two-dimensional localization (TDL) framework for mobile targets using compressive sensing. TDL is composed of two modules: (i) spatial localization module (SLM) that first achieves localization at sampling times by exploiting the sparse nature of Received Signal Strength (RSS) vector in space domain, and (ii) temporal localization module (TLM) that then achieves localization at all times by exploiting the compressible nature of location vector in time domain. Furthermore, two practicable measurement matrices are constructed to conduct linear measurements. We analyze the flexibility and effectiveness of TDL in theory. Extensive numerical evaluations with real mobility traces further confirm the superior performance of our localization framework.
