A cloud-hosted hybrid framework for consuming Web Services on mobile devices

As wireless network is becoming an standard access media in consuming Web Services for today´s mobile devices such as smartphones and tablets, it is worth investigating the challenges involved in such network. Consuming Web Services over unreliable wireless network often faces the challenges of propagating data in real-time and synchronizing them across the framework. To overcome these challenges, there is an acute need for a distributed information framework that can disseminate events in real-time over wireless network. In this paper, we propose a hybrid of REST-based and publish/subscribe event based framework to provide reliable event dissemination in mobile environment. Our cloud hosted persistent WS service channels ensures a guaranteed delivery of event messages and the adopted durable subscription mechanism assists in synchronizing event messages in the face of disconnectivity in wireless network. A prototypical implementation of the framework has been conducted for disseminating healthcare information from our developed electronic pain diary application named PIn GO. The preliminary performance evaluations show that our proposed framework is feasible and reliable for mobile devices for disseminating information over wireless network.
