Abstract

Our paper draws on research work conducted in association with the UK electricity supply industry to design and deliver a context aware application for field engineers. This research identified clear business benefits and the need for intelligent information flow algorithms, which could match information delivery requirements to the capability of the delivery networks. In turn, our work has now resulted in a proposed generic model for the design and operation of a mobile context aware distributed system. The core objective of this research is the derivation of an algorithm to allow the efficient delivery of in- formation to a user, based on the user’s context. The pseudo-code for this algorithm is presented, together with an overview of the inputs to this algorithm, of which user context is one, and the issues surrounding them. Finally there is a look towards the future and possible further refinements that might be performed on the algorithm, namely the application of fuzzy logic. …
