Issues in Nomadic Pervasive Computing

As a user roams among islands of smart spaces, additional support within the systems are needed to provide the user with seamless experience and services wherever he or she goes. We refer to such environments as nomadic pervasive computing. In this paper, we identify the open issues and suggest necessary system supports to enable such environments. Several events must occur when users move from one location to another. The space must take the users’ preferences and roaming services, and bind them to locally available physical resources. Measures should be taken to guarantee the delivery of emergency services, while ensuring some quality of service for others. The systems must be scalable and secure, and protect the users’ privacy where possible. We intend for the issues raised here to foster further thoughts about requirements and system to enable nomadicity among smart spaces.
