Abstract

With the increasing requests to the EPCIS for application in internet of things,we put forward a cache based query mechanism for EPCIS on the basis of exisiting query mechanism.The response time of query request can be shortened,when the counts of client application access to the EPCIS database is reduced.In addition,we also get a replacement algorithm based on cost function.The simulation experimental results show the proposed replacement algorithm has better performance than some other cache replacement algorithms which further improves the efficiency of the EPCIS query module.

Key words： EPCIS query mechanism; cache; cost function; replacement algorithm
