Filtration in RFID Middleware Data
Lin Qi · Journal of Chongqing Institute of Technology · 2009
As one of the most important part of the radio frequency identification(RFID) system,RFID middleware is introduced.To resolve the problem of processing great number of RFID data,data filter method becomes a very hot field for researching.Several filter methods are researched and analyzed in the article.A new design of filter method is given,which is based on the value of RFID tag event.The tag event value will be increased when the tag is reported once more,and a higher level event will be triggered by the increasing value.On the other hand,the tag value will be decreased when the tag is not reported again.Another higher level event will also be triggered by the decreasing value.The method is designed to filter the noise data which is captured by RFID hardware,and to reduce the redundant data which will be reported to the higher level.At last the method is carried out with java programming language.And combined with some assumed scenes,the feasibility and adaptability of the method is validated.
