“…The proposed scheme constructs the query index to perform the incremental evaluation of continuous queries whenever the status is changed. The query index treats queries as data and the data as queries to process incremental evaluation of continuous queries in locationbased services [19,20]. In our complex vent processing, the query index that we proposed in 2008 is used [19].…”

“…We use a query index based on bitmap which needs smaller storage and enhances the processing performance. In the query index, each node in a grid has a bit pattern which represents the relationship between nodes and queries [19]. When the primitive events occur, we can compute quickly the minimum conditions because a node in a grid without unnecessary operations is checked.…”

RFID events are a large volume of stream data that continuously come out for tracking and monitoring objects. Many studies have been done to detect a complex event in the RFID stream. However, the existing studies have many problems which increase unnecessary operations when complex events do not satisfy minimum conditions. In this paper, we propose a new scheme to detect complex events when the minimum conditions are satisfied to remove unnecessary operations. To check the minimum conditions of the complex events, we register complex queries in a query index. We detect complex events using the query index and bitmap. To demonstrate the superiority of the proposed method, we compare it with the existing methods through various experiments. As a result, it is shown that the proposed method outperforms the existing methods as a whole.
