Abstract: Device-free localization (DFL) is an emerging wireless technique for estimating the location of target. The radio frequency signal is seriously polluted due to the uncertainty of wireless channel. An extreme learning machine model-based particle filter (ELM-PF) algorithm for DFL is proposed. The proposed algorithm is used for ELM building (offline stage)and target position estimation (online stage). In the ELM building process, a radio frequency signal propagation model built by ELM is used to describe the mapping relationship between target position and radio signal strength indicator (RSSI). In the process of target position estimation, a target is tracked via particle filter with the radio frequency signal propagation model. Experimental results show that the proposed ELM-PF algorithm can eliminate the fluctuation of the wireless signals and be robust to the tracking accuracy compared with the existing Gaussian process model-particle filter (GPM-PF) and support vector machine-particle filter (SVM-PF).
