Distributed Design of a Central Service to Ensure Deterministic Behavior

Abstract

A central authentication service to EPC (Electronic Product Code) system architecture is proposed in our previous work. A challenge for a central service always arises that how it can ensure a certain level of delay while processing emergent data. The increasing data in the EPC system architecture is tags data. Therefore, authenticating increasing number of tag in the central authentication service with a deterministic time response is investigated and a distributed authentication service is designed in a layered approach. A distributed design of tag searching services in SOA (Service Oriented Architecture) style is also presented. Using the SOA architectural style a self-adaptive authentication service over Cloud is also proposed for the central authentication service, that may also be extended for other applications.
