An Autonomic Context Management System for Pervasive Computing Peizhao Hu; Indulska, J.; Robinson, R. Pervasive Computing and Communications, 2008. PerCom 2008. Sixth Annual IEEE International Conference on Volume , Issue , 17-21 March 2008 Page(s):213 - 223 Digital Object Identifier 10.1109/PERCOM.2008.56 Summary:Context-aware applications adapt to changing computing environments or changing user circumstances/tasks. Context information that supports such adaptations is provided by the underlying infrastructure, which gathers, pre-processes and provisions context information from a variety of context information sources. Such an infrastructure is prone to failures and disconnections that negatively impact on the ability of context-aware applications to adapt (and therefore dramatically impact on their usability). This paper describes a model-based autonomic context management system (ACoMS) that can dynamically configure and reconfigure its context information gathering and pre-processing functionality in order to provide fault tolerant provisioning of context information. The approach uses standards based descriptions of context information sources to increase openness, interoperability and scalability of context-aware systems.
