Middleware for mobile information access

摘要

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 but 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 middleware to support this mode of access from resource poor mobile devices that takes into consideration mobility, resource constraints and service heterogeneity.
