Abstract：

A　novel　indoor　positioning　system　based　on　received　signal　strength　(RSS)　in　wireless　networks　with　high　accuracy　is　presented　in　this　paper.　The　three　improvement　mechanisms,　called　signal　strength　filter,　user　location　filter　and　path　tracking　assistance,　are　employed　to　improve　the　positioning　accuracy　of　the　system.　The　comprehensive　performance　of　the　proposed　system　is　analyzed　in　detail　and　compared　with　the　Radar　system.　Experimental　results　demonstrate　that　the　proposed　system　in　this　paper　can　improve　80%　accuracy　in　3　meters　of　Radar　system　to　93%　in　typical　office　building　testbed.　Therefore,　the　indoor　positioning　system　presented　in　this　paper　has　the　advantages　of　high　accuracy,　low　cost　and　easy　expansibility,　and　it　can　be　used　to　locate　people　and　assets　in　the　fields　of　logistics,　healthcare,　and　manufacturing.
