This paper presents a world model for location-aware and user-aware services in ubiquitous computing environments. It can be dynamically organized like a tree based on geographica...
Location models are crucial to location-aware applications. In this paper we present two approaches for modeling location information in an infrastructure-based and an ad hoc netwo...
Gouveia et al. [3] show how to model the Hop Constrained Minimum Spanning tree problem as Steiner tree problem on a layered graph. Following their ideas, we provide three possibil...
Ubiquitous Web systems have to deal with varying context information in order to support context awareness. Accomplishing this requirement necessitates gathering, processing and r...
Abstract— The paper presents a location-aware communication approach in smart home environments. It is constructed on a symbolic location model to represent the containment relat...
