分布式RFID数据流的复合事件检测方法

摘要

The current RFID complex event detection technology has some limitation on performance and ability to process distributed data. In order to resolve these problems, this paper proposed a distributed complex event detection architecture based on CORBA (common object request broker architecture) and an efficient distributed complex event detection method based on query plan and cost estimation. The experimental study shows that the performance of this approach is remarkable in large-scale distributed RFID applications.%针对当前RFID(radio frequency identification)复合事件处理技术在性能和处理分布式应用方面的不足,提出了一种基于CORBA(分布对象请求代理体系结构)的分布式复合事件处理模型以及高效的基于查询规划和代价估算的分布式复合事件处理方法.实验结果表明,该方法在处理大规模的分布式RFID应用时是有效的.
