Resumen o descripción
Current handoffs are not designed to achieve multiple desirable features
simultaneously. This weakness has resulted in handoffs 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, we propose a new
kind of multipurpose handoff that simultaneously is seamless, autonomous,
secure, correct, and adaptive, where each desirable handoff feature can be
associated to one specific purpose. A cognitive handoff is a multipurpose
handoff that trades-off different objectives to reach its intended goals, makes
decisions considering information from the entire handoff environment, and
exhibits good performance in any handoff scenario.
The main purpose of this dissertation is to create a model-based framework
intended to understand, develop, and evaluate cognitive handoffs. Using a
holistic approach, we produce a new taxonomy of handoff scenarios,
organize handoff variables into context domains, and make structured
definitions of many desirable features. Then, using foundations on problemsolving,
functional decomposition, and model-based design, we develop a
methodology for systematically building cognitive handoffs. Applying such
methodology, we generate a cognitive handoff functional architecture and
strategies for evaluating the performance of multi-objective handoffs. Finally,
changing to a reductionist approach, we execute particular models that
integrate the functional architecture. As a proof of concept, we take the
handoff control state-based model and develop a case study about a
particular type of multi-objective handoff named correct handoff. We craft a
virtual instrument that measures the performance of the correct handoff
algorithm. A statistic analysis and probability models provide experimental
evidences that support the worthiness of multi-objective handoffs.
