Abstract. The research project CASCOM (Context-aware Business Application Service Co-ordination in Mobile Computing Environments) will implement, validate, and trial value-added support for business services for mobile workers and users across mobile and fixed networks. The vision of the CASCOM approach is that ubiquitous application services are flexibly co-ordinated and pervasively provided to the mobile users by intelligent agents in dynamically changing contexts of open, large-scale, pervasive environments. 1 CASCOM Overview The essential approach of the research project CASCOM is the innovative combination of agent technology, semantic Web services, P2P, and mobile computing for intelligent P2P (IP2P) mobile service environments. The services of our environment are provided by agents exploiting the coordination infrastructure to efficiently operate in highly dynamic environments. The IP2P infrastructure This work has been supported in part by the European Commission under the pr...
