Research And Realization Of Wireless Sensor Network Database

Wireless sensor network consists of random distribute assembly sensor, data processor unit and communication unit, which instruct selforganized network. It's aim is that cooperating sensor, collect and process sensor object information over object fields, acquire physical world useful information, include data collecting, data managing, data communicating, data processing, and through communication network carrying sensor information to sink node, finally arrive at basestation. In the end fusion reading data from each node, processing, analyzing, distributing, form a complete data graph.This paper relys on National Committee of Development and Revolution project"IPv6 wireless sensor network node". Comprehend domestic and overseas wireless sensor network research region development and future. Further more research wireless sensor network operator system, which creat theory base for researching wireless sensor network database. Paper based on wireless sensor network database in existence, focus on designing and realizing database management system TaraxDB based on TaraxOS. Include wireless sensor network database client analysis and design, node engine analysis and design, query process improve.In my paper analyse wireless sensor network system architecture and node structure, operation system model and programme model nesC. Analyse wireless sensor network database management system architecture, design and realize database system TaraxDB's primary function, Include query receive, parse, express, send query and receive result between client end and sensor network. Research TaraxDB embedded data engine structure and work principle, focus on analysing sensor node catalog and pattern manager, and analyse database query technology and aggregation function with really application improve and extend. In the end of this paper, conclude correlative work and some future work.
