An Autoconfiguring Server-based Service Discovery System

This paper presents the design, implementation, and evaluation of a service discovery system for the one.world pervasive computing operating system. Our system allows clients to find services via a central server and provides an integrated interface for sending events to remote locations. This interface is implemented via a late-binding mechanism, which allows clients to send events directly to the server where they are subsequently sent to the appropriate service. Our system aims to make configuration automatic for the server as well as the client, and this paper presents a leadership election protocol elect a server whenever one is not present. Server performance, election duration, and election scalability are evaluated.
