7 Conclusions and Outlook
The personalised and location-aware support of mobile users, an adaptive, on to logy based user model, the scalability with respect to clients and providers, the multi-agent architecture with middle-agents performing brokerage - these are promising design
concepts of the CRUMPET system. By employing middle-agents usability will also be improved as they exploit information about the expected network performance, provide agent control over transfer operations. Additional and equally important goals of CRUMPET are its contributions to the open-source agent platform implementation, FIPA-OS, primarily providing new functionality for supporting agents in "small footprint" devices, and the intelligent handling of networking problems (Poslad et al., 2001). A heuristic evaluation of a prototype has been undertaken in January 2002, in Heidelberg. Further informal evaluations of prototypes are planned in the first halfyear of 2002. The final trial and evaluation is due in summer 2002, in Heidelberg, London, Helsinki, and Aveiro. The major results of the trials shall be reported when this paper will is presented at the MobileHCI in September 2002.
