Middleware for Mobile Information Systems

Mobile information access involves retrieving information from wired service providers. Often there are situations where the information is not available from a single service provider bug can be obtained by combining information from multiple service providers. It is inefficient and sometimes impossible for a resource-poor mobile device connected over a low bandwidth wireless link to coordinate such activity. In this paper, we describe a middleware to support this mode of access from resource-poor mobile devices that takes into consideration mobility, resource constraints and service heterogeneity.
