VPDP: A Service Discovery Protocol for Ubiquitous Computing.

Many service discovery protocols have been proposed by far to support ubiquitous computing. But they don't always apply to ubiquitous computing because of their confines. In this paper, we propose a service discovery protocol named VPDP adopted in our DOM-based middleware architecture, which aims to support as many types of ubiquitous environments as possible. VPDP is important for our middleware architecture to accommodate heterogeneity and uncertainty of ubiquitous computing environments. [ABSTRACT FROM AUTHOR]
