A task migration framework based on web services in ubiquitous computing environment

Abstract

A standard Web service environment does not provide the mechanism to hold the state information for running Web services, and adding new features to Web service environments can make using Web services more difficult. In this paper, we propose a framework, which adds a checkpoint mechanism to a Web service environment, for the migration of executing Web services in ubiquitous computing. This framework provides a proper migration of services in the right situations.
