The Jini Proxy Architecture for Impromptu Mobile Services

Wireless hotspots and broadband coverage are permeating the globe giving rise to interesting spontaneous networking scenarios. The discovery and delivery of the most relevant and suitable services in a spontaneous network is a problem of paramount importance. In this paper, we propose an architecture that can support context-aware service discovery and delivery for resource-constrained mobile devices. At the heart of the architecture is the μJini proxy which mediates the discovery and delivery processes. Its delivery subsystem provides thin-client based adaptation for fat service delivery that does not fit into thin client devices. To demonstrate its effectiveness, we developed a proof-ofconcept prototype, focusing first on J2ME smart-phones.
