提出一种池分区的RFID复合事件探测方法dpool.该方法针对无用探测负载以及事件顺序发生问题,提出根据探测执行进度渐进式移入相关联事件过滤器的方法,给出了渐进式的规则;针对多查询以及复杂查询易产生过滤器干扰问题,提出查询池和事件池分区方法,给出了池分区的原则;针对事件实例之间的时序距离问题,提出设置动态时间池分区,给出了时间池分区的设置策略.实验表明dpool减少了探测复合事件的响应时间、内存的使用量,使探测的性能得到改善.
Proposed a new RFID composite event detection approach dpool based on pool partition.Aiming at resolving the issues such as useless detection load and sequence of events,dpool presents a way progressively immigrating filters-related according to the detection execution,and gives the rules of immigration;Aiming at resolving filter disturbance caused by multi-queries and complex queries,dpool presents two approaches for partitioning a query pool and an event pool,and gives the partition rules;Aiming at the time distance between event instances,dpool presents how to set a dynamic time pool,and gives the setting strategy.The experiments show that dpool reduces the response time and memory consumption for detecting composite events,therefore the performance of detection is improved.
