Two-target device-free passive localization by combining anomaly link selection and weighted-link minimum error localization

Device-free passive localization aims at locating moving objects that do not carry any localization devices. The rationale of this problem is based on the fact that a moving object can result in changes of received signal strength (RSS) of the wireless links. Existing studies only consider localization of a single-target localization or a multi-target group moving together, equivalent to a single-target localization problem. In this paper, we propose a framework for two-target device-free passive localization, where we propose a layout of Transceivers (TRXs) and a novel two-target localization method by combing the anomaly link selection and weighted-link minimum error localization (WMEL). Simulation results demonstrate our proposed layout and localization accuracy.
