Resource provisioning algorithms for service composition in Cyber Physical Systems

Out of various research challenges present in Cyber Physical Systems(CPS) resource provisioning, service composition and autonomics of self management are considered in detail. Resource provisioning means making the resources seamlessly available to user as and when they are required whereas Service composition means building a complex service when the individual service alone are not sufficient. So while composing a new service in CPS, provisioning the required resource is extremely challenging because of inherent heterogeneity in the resources and hence in the services. Besides that autonomics of self management is also very important as far as reliability of a service is concerned which means that the CPS service should be composed even in presence of critical condition. So our work focuses on identifying and solving various issues present in resource provisioning in service composition with consideration of autonomics. So this comes under the scope of a Networked CPS(NCPS). A preliminary literature survey has already been carried out in the area of resource provisioning, service composition and autonomics. In this paper we have discussed in detail about the resource provisioning in service composition and proposed solution approach. Smart City Guide is taken as case study where already deployed CPS applications from various domains like transportation, environmental monitoring, water distribution network, medical service etc. will contribute and help to take decision in providing guidance to a newcomer in the city. It may also help to the citizens by giving them prompt service in the various domains and also making them aware of the current updates in the above said domains in advance.
