Prototype of context-based adaptive communication system on seamless networking platform

A context-based adaptive communication system is introduced for use in heterogeneous networks. The context includes the user´s presence, location, available network interfaces, network availability, network priority, communication status, terminal features, and installed applications. An experimental system was developed to clarify the feasibility of using context information to flexibly control a network and applications. The system operates on a seamless networking platform we developed for heterogeneous networks. By using contexts, the system can show the caller and its callee the applications they can access that are available through the network before communication occurs. Changes of the contexts can switch the on-going application to another during communication. These features provide us with unprecedented styles of communications.
