A Platform for Linking Ubiquitous Devices and Grid Services

With rapid advances in network technology and distributed computing, Grid computing has been widely used in not only the science but also the business. Grid computing plays an important role in our daily activities. People can access and receive services from the resource constrained ubiquitous devices such as PDA and mobile phone. To allow the ubiquitous device to use the Grid resource, it is necessary for the developer to make use of a platform or middleware for linking the devices to Grid services. This paper presents a platform that provides developers with a friendly environment of developing Grid services and accessing Grid services over Globus Toolkit 4 (GT4). Furthermore, the functions are extended for developing the mobile application to access the Grid resources from the ubiquitous devices. The developer can develop the Grid applications for the ubiquitous devices more easily by using this platform, and require less special expert knowledge. This paper describes the platform architecture, the design idea, system architecture, a sample application of skin checking, accessing to a skin-expert service from a mobile phone via the proposed platform, and evaluation and comparisons with other related platforms are given in the paper.
