an open and dynamical service oriented architecture for supporting mobile services
Mobile services (m-services) play an important role in daily life and work of modern societies. Current service oriented architectures (SOA) are widely used to offer Web Services on wired networks. However, no significant research has been done in m-services field to provide availability service and dynamical discovery to mobile users. Nowadays, mobile devices are characterized by limited resources such as processing power, memory, display screen and connection bandwidth. In this context, we propose a service oriented architecture that addresses the following issues: (1) dynamical integration of new services by providers at anytime, (2) dynamical discovery of available services and (3) the use of open source software to develop the solution. With this approach, users require no prior knowledge of accessible services nor require updating the application of their mobile devices when new services are incorporated. The paper includes results with service scenarios, showing that Web Services can safely be used as paradigm to support m-services.
