Research on Multi-dimensional RFID Complex Event Processing Optimization Algorithms
Lin Chen · Jisuanji fangzhen · 2009
Complex Event Processing(CEP) is a key technology of RFID data management.However,current CEP algorithms correlate raw RFID events with the same TagID,and are only applied to single property comparison.To deal with the limitations of current algorithms,the paper proposes a multi-dimensional complex event processing optimization algorithm(SIMOA).With the algorithm,CEP is extended to a general relation model which is more extensive than TagID dimension comparison based problems.Intermediate results are propagated by the network mode which reduces the state update cost and improves the efficiency of CEP greatly.Extensive experiments verify the effectiveness of the algorithm.
