Adaptability of dynamic changes in the user's needs is considered as one of the important qualities to be possessed by a software system in pervasive environment. The work described in this paper proposed the solution for creating dynamic adaptable system through encapsulating dynamic changes using aspect-oriented approach. In the proposed solution, an ‘aspect’ is defined as the unit of representing dynamic changes in the user's requirements. The system can adapt to the changes by weaving redefined aspects with the components associated with the changes without affecting the existing structure of a system. Also, a new adaptability metric has been proposed using the principles of coupling. Using this adaptability metric, the adaptability efficiency of a system that uses the proposed approach is measured and its adaptability value is shown to be higher, if the number of components associated with the change is more than a system that uses the conventional approach for representing and implementing dynamic changes.
