基于内存受限的RFID复杂事件处理优化算法
RFID complex event processing optimization algorithm with memory constraint
摘要
Abstract
Complex event processing (CEP) is a key technology of RFID data management. But the massive stream of realtime data may cause memory bottlenecks, data placed in external storage and restrictions on large-scale deployment of RFID. So this paper proposed a BIOT ( B Plus tree indexing optimization of time-slicing) algorithm. With memory constraint, according to timing sequence, the data stream would be divided into segments which would be indexed by B + - tree, then to avoid frequently searching pre-event at external storage matched complex event with the guide of statistical law. This algorithm has greatly reduced the I/O overhead and increased throughput. In addition, correlated comparative experiments are carried out to verify the effectiveness of the algorithm.关键词
