The Role of Context in Cognitive Systems

Abstract

To make effective decisions, a cognitive radio needs to understand its operating context. Over the past several months, the Wireless Innovation Forum’s Cognitive Radio Work Group has been exploring how to enable a cognitive radio to represent, understand, and share its context. Material to be covered in this paper includes the following:

  • What exactly is meant by “context” in varying published existing context-aware applications

  • The role of context in communications and information systems

  • A survey of tools and software for developing context-aware applications

  • A new model of the interactions of the real world, symbolic reasoning and representation, and acting on the reasoning

  • Relating the components of a key context-aware tool to the new model

  • Initial work coding a java-based context-aware application for a cognitive radio to reason and act on its context

This paper provides greater detail and context to a presentation given at WinnComm 2013 and reviews work performed on the subject since the earlier presentation.
