Abstract
Pervasive computing, with its focus on users and their tasks
rather than on computing devices and technology, provides
an attractive vision for the future of computing. But, while
hardware and networking infrastructure to realize this vision
are increasingly becoming a reality, precious few applications
run in this infrastructure. We believe that this lack of ap-
plications can be attributed to three characteristics that are
inadequately addressed by existing systems. First, devices
are heterogeneous, ranging from wearable devices to con-
ventional computers. Second, network connectivity often
is limited and intermittent. And, third, interactions typi-
cally involve several autonomous administrative domains. In
this paper, we introduce a system architecture that directly
addresses these challenges. Our architecture is targeted at
