    A pervasive environment needs to take account of a user’s context and preferences in determining which services to provide to the user. Moreover, one of the important features of a pervasive service environment is its dynamic nature, with the ability to adapt services as the context of a user changes, e.g. as he/she moves around. This paper describes how these requirement changes can be sufficiently accounted for by using a personalisation component to ‘decide’ what a user needs, and a composition component to continuously monitor services and the changes associated with them. The paper presents how services can be recomposed dynamically if the changes in context require it. This approach has been incorporated into a platform to support pervasive services. The service composition process used is described, and the way in which personalisation is incorporated into this process is shown. Finally the paper provides a brief account of two prototypes built as a proof of concept for these ideas.
