A Runtime Resource-Management Framework for Embedded Service-Oriented Systems

Service-Oriented Computing (SOC) has rapidly progressed in recent years, with examples appearing in numerous application areas including business processes, high-performance computing, web-based services, and embedded systems. In the embedded systems domain, ubiquitous devices, context-aware systems, and sensor networks are increasingly being used in a plethora of areas. However, because of the nature of their operating environment, service-oriented embedded systems (SOeS) pose unique challenges to quality management. SOeS have to contend not only with the quality of services from providers, but also with the constrained system resources in their operating environment. SOeS need to efficiently utilise available system resources by dynamically adapting themselves to changes in their runtime environment. This paper discusses current SOC resource-management initiatives, setting out the challenges that SOeS systems must overcome, and proposes a pluggable, runtime resource-management framework for SOeS.
