Abstract

Wide area sensor databases are a hotspot research area internationally at present. The query processing technology in wide area sensor databases is analyzed in detail. Based on it, the method of query equal decomposition is proposed. Firstly, the complexness query is divided into a number of sub-queries equally. Secondly, these sub-queries are processed respectively. Finally, all the results of sub-queries are united and the final query results are sent to the user. Experiment results demonstrate that the method can not only dramatically reduce the users´ query response times, but also reduce the messages that transmitting in the sensor network largely and improve the utilization ratio of the network bandwidth.
