Pervasive computing provides an attractive vision for the future of computing. Computational
power will be available everywhere. Mobile and stationary devices will dynamically connect and
coordinate to seamlessly help people in accomplishing their tasks. For this vision to become a
reality, developers must build applications that constantly adapt to a highly dynamic computing
environment. To make the developers' task feasible, we present a system architecture for pervasive
computing, called one.world. Our architecture provides an integrated and comprehensive framework
for building pervasive applications. It includes services, such as discovery and migration, that help
to build applications and directly simplify the task of coping with constant change. We describe our
architecture and its programming model and reflect on our own and others' experiences with using
it.
