dpool:a Pool Partition Approach for RFID Composite Event Detection
Li Xiaoguang · Journal of Chinese Computer Systems · 2011
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.
