摘　　要：传统的发布/订阅系统不支持具有丰富时序关系的复合事件,不能很好地满足无线射频识别应用的需要。针对无线射频识别应用的特点,设计了面向无线射频识别应用的复合订阅语言,研究了订阅语言的组成和使用,基于时间事件、复合订阅的匹配图表示、事件检测的消费语义,给出了相应的复合订阅匹配算法。该算法已在OncePubSub系统中实现,并与Siena改造版J、ESS改造版进行了性能比较。Traditional publish/subscribe systems couldn＇t support the composite events with abundant temporal constraints, so that they couldn＇t satisfy all needs of Radio Frequency IDentification （RFID） applications. Aiming at RFID-related application characteristics, a composite subscription language was designed, the composition and use of subscription language were studied, and a matching algorithm for detecting composite events was proposed based on the time event, matching graph of composite subscription as well as consumption semantic of time test. This algorithm has been implemented in our OncePubSub system. Performance comparison results indicated the proposed algorithm was more efficient than the two systems developed on the basis of Siena and JESS respectively.
