Study On Positioning System Based On Wireless Sensor Network

With the continuous improvement of wireless sensor technology,wireless locationservice needs of people’s daily life also more and more. In the forest fire, undergroundmine, the parking lot etc.positioning service, it plays a great role, improve people’sworking efficiency and living standard. Wireless sensor positioning is the birthanddevelopment of wireless sensor network technology, is the basic application of wirelesssensor network, application prospect and the research value is high.The research status of location system based on wireless sensor network at home andabroad is introduced in this paper, the research background and significance of this paper,presents a positioningsystem based on ZigBee, the signal strength received by thedetectionmethod to determine the relative positions of the nodes. Thecoordinator is a corecomponent of the man-machine interactive, the place of the reference node known andpositioning requires determination of the node network, these three parts constitutethepositioning system. Node localization using CC2431chip, study the location ofpositioning engine using its internal, and analysis the mainflow and the core algorithm ofthe system, finally set up theexperimental platform. Through the experiment, thepositioning precision of the system were determined, it draws a conclusion and future workobjectives.
