Abstract

Abstract: The perception layer of Internet of Things (IoTs) is mainly composed of Multiple Wireless Sensor Networks (MWSNs). Data query processing is a very important research area in MWSNs. Join queries can monitor similar network environments in different positions. In general join algorithm, each ordinary node sends its join attribute value to the database server. The database server finds out the result set which meets the join conditions. In distributed join algorithm, the ordinary nodes predict their filters of next round and the database server obtains the global, common filters. The nodes which meet the join conditions send their data to the database server and the database server obtains the final result set of matching nodes. Experiments on real-world data set show that the algorithms outperform the typical algorithm.
