A context broker federation for QoC-driven selection of cloud-based context services
Elarbi Badidi · 2014
Context services typically provide infrastructure support for collection, management, and dissemination of context information concerning a number of subjects. Subjects may be users, objects such as handheld devices and equipment, or the environment of users. We propose, in this paper, a federation of cloud-based context brokers for context services selection. Context Brokers (CBs) of the federation cooperate to assist context consumers' select suitable context providers, which can offer their required context information and fulfill their quality-of-context (QoC) requirements.
