SMJ:synopsis-based data stream multi-join operation

Zhang Jun-hu

Abstract

This paper studied the characteristics and the applications of Ad hoc networks,and analyzed the problems of the traditional methods of multi-stream join processing in Ad hoc networks.Based on this,proposed a synopsis-based multi-stream join optimization algorithm——SMJ.The experiments show that this method can greatly reduce the communication cost.
