As a result of combination of microsensor technology,low power computing and wireless networking,wireless sensor networks become an active branch in scientific territory of computer science at the moment.The recent reserch work on data management of wireless sensor networks is mainly introduced. In order to achieve high performance of the data-center network system,and supply an effective sensor database administration processing system in the interest of observing person or consumer,Separately proposed valid settlement schemes for the two key problems in database technology: data model and query processing.
