Dynamic Information Dissemination to Mobile Users

We propose an information push model for information dissemination to mobile users, called the dynamic channel model, which is a set of extensions to the conceptual models developed for information channels that capture mobility-specific requirements. Dynamic channels are used for filtering and setting update order priorities for the information that users intend to monitor, which depends on their location and changes as they roam. We also present the architecture of Ubitata, our framework for information dissemination to mobile systems. We then introduce our development process for a class of mobile computing applications operating under an information dissemination metaphor.
