Abstract
We have designed a novel positioning system, the Coopera- tive Location-sensing system (CLS) that employs the peer- to-peer paradigm and a probabilistic framework to estimate the position of wireless-enabled devices in an iterative man- ner without the need for an extensive infrastructure or time- strenuous training. CLS can incorporate signal-strength maps of the environment to improve the position estimates. Such maps have been built using measurements that were ac- quired from Access Points (APs) and peers during a train- ing phase. This paper makes three important contributions. First, it uses a particle-flters-based framework to model the- oretically CLS. Second, it proposes new algorithms that in- corporate real-life signal strength measurements from (APs) and peers to estimate position and distance. Third, it evalu- ates the performance of CLS via real-life measurements and extensive simulation, and compares it with other positioning systems. We have implemented and evaluated the CLS pro- totype along with its variants using IEEE802.11 and Blue- tooth, and compared its performance with other positioning systems.
