Abstract

The core technical issue in XML message brokers, which play a key role in exchanging information in ubiquitous environments, is processing a large set of continuous XPath queries over incoming XML streams. In this paper, a new system as an epochal solution for this issue is proposed. The system is designed to minimize the runtime workload of continuous query processing by transforming XPath expressions and XML streams into newly proposed data structures and matching them efficiently. Also, system performances are estimated both in terms of space and time, and verified through a variety of experimental studies, showing that the proposed system is practically linear-scalable and stable in terms of processing a set of XPath queries in a continuous and timely fashion.
