Service Composition Issues in Cyber Physical Systems and Middleware Design

Today Cyber Physical Systems (CPS) has spanned through all Smart Applications of day to day life. These applications range from Smart Transportation, Smart Water Management, Smart Grid, Smart Office, Smart Home Automation and many more. The services provided by CPS applications is making our life easy but in comparisons with software services provided by Service Oriented Architecture (SOA), the services provided by CPS are different in many aspects. As there is a tight coupling of cyber and physical space so while defining and describing the CPS Service, we need to take into consideration the involvement and impact of physical space too. Besides that Service Composition is one of the major challenge present in Cyber Physical systems which by definition means to combine more than one services to achieve a specific task where individual services are not sufficient. So we need to consider provisioning of appropriate resource also in order to achieve the job of service composition. And while solving this Service Composition and Resource Provisioning challenges, we need to take care of the inherent challenges of CPS as well. In this paper we present issues in SC and then a middleware approach to resolve issues of Service Composition and Resource Provisioning challenge which considers Resource as well as Service simultaneously.
