Study and Design of Wireless Sensor Networks Query System Based on Statistical Models

Aiming at meeting the performance requirements of real-time response and energy reservation in the technology of wireless sensor network data processing,this paper designs a new structure of wireless sensor network querying system.The system uses a new two-tier architecture as the system processing architecture,and uses one kind of statistical models as physical world model to optimize the querying process.At last,it gives the performance contrast of this WSN querying system and other WSN querying system.According to the data of the analysis contrast,the query system based on statistical models greatly promotes the efficiency of query processing,and saves energy consumption of wireless sensor network.
