Abstract

This paper introduces a comprehensive architecture that supports adapting a client device's functionality to new services it discovers as it moves into a new environment. Users wish to invoke services --- such as controlling the lights, printing locally, gaining access to application-specific proxies, or reconfiguring the location of DNS servers --- from their mobile devices. But a priori standardization of interfaces and methods for service invocation is infeasible. Thus, the challenge is to develop a new service architecture that supports heterogeneity in client devices and controlled objects while making minimal assumptions about standard interfaces and control protocols. Four capabilities are needed for a comprehensive solution to this problem: 1) allowing device mobility, 2) augmenting controllable objects to makethem network-accessible, 3) building an underlying discovery architecture, and 4) mapping between exported object interfaces and client device controls. We motivate the n...
