Towards Ubiquitous Web-Based Learning

This technical report introduces goals and early findings of a multi-year multi-party project MUNDO. MUNDO is a pool of services and enablers for mobile and ubiquitous computing. It emphasizes easy global evolutionary deployment as a migration path for the Internet as a whole towards a nomadic computing economy. The nomadic users access the network via personal devices and associated public and private appliances. The network is liberated from common constraints such as central operators and fixed home bases of users. It hosts services which are by themselves migratable and highly adaptive with respect to region and context-awareness, quality variations, and terminal characteristics. Migration and adaptation may be realized by different implementations of the same service. An underlying general cost model helps to mediate user desires and service offerings. A number of scenarios and corresponding MUNDO application pools are described in order to motivate the features and scope of MUNDO. We describe a "radio on steroids " application pool called DACAR in more detail. We outline the architecture of MUNDO and elaborate its system services
