Abstract


In recent years, with the rapid development of wireless communication technology , sensor technology , information acquisition and processing technology , the low-cost, low-power , multi-purpose micro wireless sensor nodes . Wireless sensor networks by these random distribution of the integrated sensor , the data processing unit and the communication module tiny node network formed by self-organization , which is in cooperation with perception, the acquisition and processing of the network coverage area information of the sensing target , to obtain valuable information of the physical world . In order to better support a variety of applications , to build a wireless sensor network database to achieve effective data management and access , it is a new field of study . This paper analyzes the wireless sensor network architecture and the composition of the sensor nodes , wireless sensor networks embedded operating system, laid the foundation for the study of wireless sensor network database design and implementation . Wireless sensor network database system TaraxDB is divided into two parts of the embedded database engine running on the database front-end and node . The database front-end application and the sensor network interface is responsible for the reception of data and commands issued . The embedded database engine running on each node is responsible for data collection, storage and delivery , is also responsible for receiving and executing commands . Discussed in detail a number of issues in the design and implementation of the database system , including the design of the various functional modules in the front-end interaction with the user , and sensor networks interact nodes . Research analyzes the wireless sensor network database query processing techniques , analysis of the data model and query language the TaraxDB system was extended by adding a distributed query processing module , a query processing optimization method , and finally on the system performance testing and results analysis . Finally a summary of the relevant work to do , pointed out a number of deficiencies in the research work , the future research work .
