Integrated quality of user experience and quality of service approach to service selection in internet of services

Abstract

Discovery and retrieval of an ideal service in an SOA-like infrastructure comprising a resource-constrained hosting platform is really a challenging job. In this paper, we propose the simple service selection component for IoS, which selects the services that have maximum utility value over Quality of Services (QoS) and Quality of User Experience (QoUE) attributes. The novelty behind the proposed middleware development is in achieving high-degree configuration and customisability by selecting a subset of middleware functionality depending on the need. The conventional service selection approaches do not consider QoUE and QoS as a whole; they expect the user to provide a set of QoS constraints. The selection approach is based on the MAUT (Multi-Attribute Utility Theory) decision-making method. The experimental results are encouraging and the middleware performs well when compared to the constraint model and linear programming models.
