Abstract

The emerging pervasive computing services will eventually lead to the establishment of a context marketplace, where context consumers will be able to obtain the information they require by a plethora of context providers. In this marketplace, several aspects need to be addressed, such as: support for flexible federation among context stakeholders enabling them to share data when required; efficient query handling based on navigational, spatial or semantic criteria; performance optimization, especially when management of mobile physical objects is required; and enforcement of privacy and security protection techniques concerning the sensitive context information maintained or traded. This paper presents mechanisms that address the aforementioned requirements. These mechanisms establish a robust spatially-enhanced distributed context management framework and have already been designed and carefully implemented.
