A location-adaptive virtual networked appliance

Abstract

The paper presents a new way of constructing a Virtual Networked Appliance (VNA) middleware using location information. In the VNA architecture which we proposed in our previous work (J. Nakazawa et al., 2000), adaptation to the location of a user has not been clearly specified. We call such a location adaptive VNA "L-VNA". In L-VNA, location management is encapsulated in the runtime of VNA, thereby eliminating a user's explicit decision for location adaptation. We have implemented L-VNA over JDK1.2 and demonstrated its validity.
