Abstract

The immanent and pervasive use of mobile devices, especially in wireless environments, raises issues about the context awareness and sensitivity of applications. As the use of embedded mobile devices grows in vast quantity, the need for efficient context gathering, representation and delivery evolves. With regard to this situation this work describes problems concerning context sensing, representation and delivery and proposes a new approach for context based 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 different showcases of time and event triggered context sensing in wireless environments.
