Abstract

Highly mobile people (HMPs) tend to require flexible, reactive service delivery due to their regularly changing location and activities and the lack of a wired internet connection most of the time. A ubiquitous service delivery system that is able to dynamically deliver services in response to relevant events that occur, such as changing location, availability of new lastminute specials, work opportunities and safety issues could provide added value while retaining flexibility. This paper describes such a system. An engineering research approach has been adopted to design the system. Issues addressed include HMP and service states and events, context, situations and situation-action rules. An architecture is proposed that is based on distributed, co-operating software agents and mobile data technologies. The role of these agents is to continuously monitor situations that are occurring in the physical and virtual service spaces and to take the required action for any situations that are relevant to the HMP.
