Policy-based Context-aware Adaptable Software Components for Mobility Computing

The adaptability of software applications is a very demanding feature nowadays. The main contribution of this paper is to propose a concept of policy-driven software framework supporting adaptable components called spontaneous objects. Spontaneous objects are lightweight adaptable context-aware software components. The adaptability mechanism is split between spontaneous objects and a spontaneous object container which creates a runtime environment for spontaneous objects. The paper describes the benefits achieved due to the policy-driven approach, a complete runtime architecture for spontaneous object implementation, a programming model and a case study
