Mobility Support Framework in Adaptable Service Architecture

Mobility is regarded as the most important feature needed to achieve adaptability and flexibility in the executing of service components. As such, service system could be able to cope with the handling of dynamic changes in the availability of resources and position of users. On the other hand, providing user-centric and personal-content driven wide range of services, more commonly wireless ones, to end users regardless of their location and used equipment, seem to be the most asked for demand by users. This is the main motivation behind investigating and developing mobility support in any Adaptable Service Architecture. Mobility, in this context, is a feature facilitating the free and coordinated movement of, for instance, users, software components, user terminals, etc. One should always consider the vibrant configuration and settings of not only end-users applications and environment, but also the network resources, components and services. The reason is due to ever changing and increasing demands and requirements in both functionality, security, reliability and QoS. Mobility support in selfmanaging, dynamically configurable network architecture seems to be even more challenging, however recent development and improvements in network infrastructure show a greater prospect for code-on-demand and adaptive network management. TAPAS, and its mobility handling architecture, presented in this paper, tend to give some answers and take a step towards achieving such goals.
