摘要: Transceiver-free object tracking is to trace a moving without carrying any communication device in an environment where the pre-deployed with some monitoring nodes. Among all technologies, RF-based technology emerging research field facing many challenges. Although we proposed original idea, until now there no method achieving scalability sacrificing latency and accuracy. In this paper, put forward real-time system RASS, which can achieve goal promising applications like safeguard system. Our basic idea divide into different areas, adjacent areas using channels. So interference among be prevented. For each area, three communicating nodes are deployed on ceiling as regular triangle monitor area. use Support Vector Regression (SVR) model locate object. This simulates relationship between signal dynamics caused by position. It not only considers ideal case of object, but also utilizes their irregular information. As result it reach accuracy around 1m just area 4m side. The experiments show that RASS bounded about 0.26s. scales well large deployment
