A Cognitive Handoff: Holistic Vision, Reference Framework, Model-Driven Methodology and Taxonomy of Scenarios
Current handoffs are not designed to achieve multiple desirable features simultaneously. This weakness has resulted in handoff schemes that are seamless but not adaptive, or adaptive but not secure, or secure but not autonomous, or autonomous but not correct, etc. To face this limitation, in this paper, the authors envision and develop a new kind of handoff system, which is context-aware in the sense that uses information from its external and internal environment: a cognitive handoff. Thus, the resulting cognitive handoff can attain multiple purposes simultaneously through trading-off multi-criteria and based on a variety of policies.
