Abstract

The ubiquity of wireless ad hoc networks and the benefits of loosely coupled services have fostered a growing interest in service oriented architectures for mobile and pervasive computing. Many architectures have been proposed that implement context-sensitive service discovery, selection and composition, or that use a component-based software engineering methodology to facilitate runtime adaptation to changing circumstances. This paper explores live service mobility in pervasive computing environments as a way to mitigate the risk of disconnections during service provision in mobile ad hoc networks. It focuses on context-aware service migration and diffusion to multiple hosts to increase accessibility and expedite human interaction with the service. We analyze the basic requirements for service mobility and discuss an implementation on top of OSGi. Finally, we evaluate our approach to service mobility and illustrate its effectiveness by means of a real-life scenario.
