RFID complex event processing optimization algorithm with memory constraint
基于内存受限的RFID复杂事件处理优化算法 *

Complex event processing(CEP) is a key technology of RFID data management.But the massive stream of real-time 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,accor-ding 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 sto...
