An Indoor Positioning System Based on
Wireless Sensor Networks
Abstract: An indoor positioning system based on WSNs is developed using C#. The object is to build a practical software system to fit actual application requirements. There are six parts in the paper: introduction, system analysis, system design, system implementation, system testing, and conclusion. The main contents include the research background, purpose and significance analysis; the feasibility analysis and the demand analysis of software system; the overall design idea analysis of the system, including function pision and database design; the exposition for each function module’s realization process and the analysis of the main program code; the test for the implemented system function module and the analysis of existing problems and deficiencies; the design summary.
Key words: indoor positioning; wireless sensor network; C#; SQL server；position error
