—Many pervasive computing applications demand expressive situational awareness, which entails an entity learning detailed information about its immediate and surrounding context. Previous work has largely focused on individual entities' context, in this paper we present Grapevine, a framework for efficiently sharing context information in a localized region(More)
Acquiring accurate context information is crucial to mobile and pervasive computing, and sharing context among nodes enables unique applications. As context information and the applications that consume it become increasingly diverse, they will need an efficient means to indicate tailored interest in this context information. This paper proposes a new(More)
—Many pervasive computing applications demand expressive situational awareness, which entails an entity in the pervasive computing environment learning detailed information about its immediate and surrounding context. Much work over the past decade focused on how to acquire and represent context information. However, this work is largely egocentric,(More)
