Abstract


Physical information and location information associated only with the actual value of the use of wireless sensor networks (WSN) applications , thus wireless sensor network node location information is essential problems and hot spots of the sensor network research . In this paper, the background for the application of the navigation system , independent research and development of a wireless sensor network information collection platform node location information acquisition , processing and application of the design and development of the navigation system . First, the absolute positioning of the node with a global positioning system (GPS) by design and based on the received signal strength indication (RSSI) ranging between the wireless sensor network node relative positioning , to meet the positioning needs of the indoor and outdoor wireless positioning system ; then combine wireless sensor network system to develop a set of human-computer interaction , geographic information systems ( GIS ) , the node location information processing and visual display on the electronic map ; Finally, the application of GIS location information resources to design a path search , real-time tracking of the trajectory path search system in order to achieve a complete navigation system . The design of the navigation system as a whole is interspersed in the design of the sensor nodes of the wireless sensor network platform systems , data collection systems , data storage and analysis system . Done a lot of testing of targeted work in the area of wireless positioning ; every detail in geographic information systems , electronic map also do the corresponding work to achieve a combination of wireless sensor network platforms and geographic information systems ; improved shortest path implementations of the algorithm in a geographic information system for quick navigation path query. Ultimately this paper, completed on the basis of all design and manufacturing system , the campus practice model , the testing and use of the system as a whole , achieved the desired effect , the practical value of the system is proved .
