Context Sensing, Aggregation, Representation and Exploitation in Wireless Networks

Abstract

As the use of wirelessly connected embedded mobile devices grows in vast quantity, their situative use and context sensitive behavior becomes an essential feature. For the implementation of context awareness in mobile appliances, the need for the efficient gathering, representation and delivery of context information evolves. This paper describes issues related to context sensing, representation and delivery, and proposes a new approach for context based mobile computing: Time and event triggered context sensing for mobile devices and an abstract (application and platform independent) representation of context information is introduced. The paper presents showcases of time and event triggered context sensing in wireless environments.
