A bio-inspired approach for autonomous service components configuration in dynamic environments

Abstract

Ubiquitous computing environments require dynamic adaptable application and network services because of their need to adapt to rapidly change context. To support such environments, management systems need to dynamically adapt service execution and behavior. This paper explores an approach to make service plans more adaptable to changing context prior to as well as during execution time without re-planning. This paper proposes a bio-inspired approach to describe the adaptive behavior of a particular service and the formation of composite components representing the constituent services. The paper depicts the policies to be used as rules by which adaptive behaviors can be specified prior to, or even during, execution. For a composite service, these policies are refined and applied to its constituent services, thus facilitating automatic refinement of high level policies to lower level policies executable appropriate constituent service. The paper presents a case study to illustrate the outlined approach and identify the strengths and challenges in applying this approach.
