Abstract

Web services introduce new capabilities in the distributed application development model. This model is built on widely used internet standards, thereby presenting interoperability among different platforms. However, there are still several restrictions within the current standards, for instance, lack of the capability to react swiftly given poor-performance or requirements of maintenance on the host that is executing the web service. This paper proposes a nomadic and resource-aware web service framework, which provides the capabilities of migrating a web service to different hosts dynamically and adjusting itself to the available resources of the new host. Therefore, allowing web services to react as a result of run-time requirements and poor-performance of hosts, as well as placing itself closer to the group of clients that frequently accesses the web service for performance enhancement. Such an approach is applicable to ad-hoc networks of individually resource-poor mobile devices. Implementation issues are also discussed and demonstrated.
