Research and Improvement on Key Technology of RFID Complex Event Processing
Xiaowei Wei · Computer Technology and Development · 2012
RFID complex event processing is an emerging technology to handle a large number of simple events and sort out the valuable events.Compared to the traditional events,RFID events have the following characteristics:large volume,temporality and spatiality,inaccuracy etc.Based on the analysis of the characteristics of RFID data,research and improve the key technology of RFID complex event processing,focus on RFID data cleaning technology and event detection technology.For the RFID data cleaning,a multi-level filtering approach,which can obtain data closer to the real situation,has been proposed.And for event detection,local detection and global detection has been combined to get more meaningful data for the upper application.Finally,give an outlook of development trend of RFID complex event processing.
