Abstract: Disseminating multimedia content to users in a mobile computing environment such that they receive it in an appropriate and timely manner is fundamental to the success of mobile information systems. Too often, however, this endeavour is hindered by the poor data rates supported by wireless telecommunications networks and by the limited computational resources available on mobile devices. We describe an approach to overcome these limitations, which is based on extremely dynamic and proactive precaching. This approach, which we have termed intelligent precaching, is realised through the innovative deployment of intelligent agents on mobile devices. To illustrate this concept, the design and implementation of an archetypical mobile computing application is provided, namely that of an electronic tourist guide. This is augmented with a description of the salient points derived from a user evaluation, from which emerging avenues for further research are identified.
