Dynamic Information Dissemination to Mobile Users

We present the dynamic channel model, an information push model for data dissemination to mobile users. This 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. The dynamic channel model was implemented in Ubidata, a software framework for the construction of systems for information dissemination to mobile users.
