Achieving Web Service Continuity in Ubiquitous Mobile Networks: the SRR-WS Framework

In this paper, we will address two underlying problems of Web service continuity in mobile ubiquitous networks. On the one hand, our work presents a lightweight solution for connection interruption. On the other hand, we introduce a technique to switch between devices during service invocation. The Suspend-Relocate-Resume for Web Services (SRR-WS) Framework meets these challenges by allowing a device to disconnect in-between Web service invocation and response in order to retrieve the reply upon reconnection. Moreover, our proposed framework also enables on-demand transfer of service control from one device to another. Our first reference implementation demonstrates how Web service continuity can be achieved across devices as well as unreliable connections.
