A framework for mobile Web services

By John Cox, NetworkWorld.com, 07/18/06

A recent paper at IEEE Distributed Systems outlines a way to adapt Web services to mobile environments by using mobile agents.

The authors of the paper are trying to create a framework that can run across the diversity of mobile platforms, using Web services standards to simplify access by handhelds to desktop and server applications.

"In this article, we’ll describe our agent-based mobile services framework. It uses wireless portal networks and eliminates XML processing on mobile clients. It also offers dynamic service selection and rapid application development and deployment for Web service providers."

To the standard Web services architecture of service provider, requestor, and registry, the authors propose three new components: a service broker, a workflow engine, and a mobile Web service agent. "Mobile Web service agents use SOAP messaging to query the service broker and HTTP messaging to communicate with the workflow engine."
