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...
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 in this paper. Focusing on the query redundancy problem among multiple queries, the multiple queries processing algorithms are proposed. First of all, it divides these queries into a number of sub-queries equally. Secondly, it constructs...
