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

Automatic Extraction of Conversation Protocols from a Choreography Specification of Ubiquitous Web Services
While web service technology is becoming a de facto standard for integration of business applications, it is also rapidly emerging as an effective means for achieving inter-operability among the devices in network centric ubiquitous systems. When such a web service enabled device engages in a conversation with a service provider, it becomes necessary to define an interaction logic required betw...
متن کاملAdaptive Web Service Migration
In highly dynamic and heterogeneous environments such as mobile and ubiquitous computing, software must be able to adapt at runtime and react to the environment. Furthermore it should be independent of a certain hardware platform and implementation language. In this paper, we propose an infrastructure for self-adaptive migratable Web services (SAM-WS) for implementing applications for such envi...

متن کاملA procedure for Web Service Selection Using WS-Policy Semantic Matching
In general, Policy-based approaches play an important role in the management of web services, for instance, in the choice of semantic web service and quality of services (QoS) in particular. The present research work illustrates a procedure for the web service selection among functionality similar web services based on WS-Policy semantic matching. In this study, the procedure of WS-Policy publi...
متن کاملScaling Mobile Enterprise Through Cloud Computing
Web services (WS) are going mobile. A Mobile Enterprise can be established in a cellular network by participating Mobile Hosts, which act as WS providers, and their clients. Mobile Hosts enable seamless integration of userspecific services to the enterprise, by following WS standards, also on the radio. The paper summarizes the challenges and research associated with establishing Mobile Enterpr...
