Advancing technology in wireless communication offers users anytime, anywhere access to information and network resources without restricting them to the fixed network infrastructure. Mobile computing represents a shift in the distributed systems paradigm. The potential of decoupled and disconnected operation, location-dependent computation and communication and powerful portable computing devices gives rise to opportunities for new patterns of distributed computation that require a revised view of distributed systems. Mobile environment brings different challenges to users and service providers when compared to fixed, wired networks. Mobility brings uncertainties, as well as opportunities to provide new services and supplementary information to users in the locations where they find themselves.
