Application of Arc in System Design

Current and future mobile communication systems require the combination of high performance technology from very diverse engineering disciplines. Consequently, these systems are complex by nature, which complicates system-wide Quality of Service optimisation. In this paper we consider system-wide optimisation of resource distribution within the framework of a given (static) architecture but with components that do support multiple modes of operation. We take into account variable type of applications, quality requirements, resource availability, and external context. In this paper we use the concepts of Adaptive resource contracts (ARC) to capture and exploit the capabilities of individual components in the system. A relevant case study demonstrates the added value of the ARC concepts for system design. Eventually the method yields a specification of individual system components and an indication of the optimised overall
