We propose an information push model information dissemination to mobile users, called dynamic channel model. It is a set of extensions to the conceptual models developed for information channels, capturing mobility-specific requirements. These 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 Ubidata, an adaptable framework for information dissemination to mobile systems. We introduce our development process for a class of mobile computing applications operating under an information dissemination metaphor.
