Situation-awareness for adaptive coordination in service-based systems

Abstract

Service-based systems have many applications, including collaborative research and development, e-business, health care, environmental control, military applications, and homeland security. Service coordination is required for these systems to coordinate distributed activities. To achieve adaptive service coordination under changing environment and workload, situation-awareness is needed. In this paper, a model is presented for situation-awareness (SAW) requirements in service-based systems. Based on this model, SAW agents are developed to incorporate situation-awareness and adaptive coordination in service-based systems.
