RFID数据流分布式层次复杂事件处理

当前RFID应用中的复杂事件处理通常采用集中式的体系结构，这样不能适用于分布式的应用，并且由于存在单点失效和网络拥塞而缺乏健壮性和可伸缩性。同时，很多高效的RFID复杂事件处理方法不能很好地支持层次复杂事件。提出了一种基于CORBA的分布式层次复杂事件处理模型以及高效的基于查询规划的分布式层次复杂事件处理方法。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。

Distributed hierarchical complex event processing for RFID stream

The current methods of Complex Event Processing（CEP） in RFID application usually focus on centralized architecture,which can＇t support distributed RFID application.The centralized CEP also lacks of robustness and scalability because of single point failure or network break.On the other hand,hierarchical complex event is not supported well in many efficient complex event detection methods for RFID.Distributed hierarchical complex event detection architecture is proposed which is based on CORBA（Common Object Request Broker Architecture）.A high performance plan based distributed hierarchical complex event detection method is proposed which uses parallel method to improve performance.The experimental study shows that the performance of this approach is remarkable in large-scale distributed RFID applications.
