Abstract


Wireless sensor networks (WSNs) is a network of sensor nodes for sensing , acquisition and processing of the perception of the object information in the coverage area , and then will get the information sent to the data center . In sensor networks , data management and query is one of the main research content . In this paper, the wireless sensor network data management background , meaning and Research , the consumption of a large-scale wireless sensor networks balanced multi- query algorithms . The main idea of the algorithm is to take advantage of regional commonalities query query multiple queries to merge , thus minimizing the number of queries , query execution process will not be affected by the limited impact of the network resources to make large-scale data . The thesis is divided into two parts: First, on the basis of the analysis of the basic concepts of the sensor network , the introduction of the knowledge of the sensor network data management , sensor network data management in detail . Second , the analysis and comparison of sensor network data query processing algorithms , a simple and effective data query algorithm research . The simulation results show that the consumption of such large-scale wireless sensor networks balanced algorithm in the case of correct selection of parameters , is superior than the traditional query methods .
