A investigação atual sobre redes sem fios heterogéneas centra-se principalmente na seleção sem descontinuidades da melhor rede de entre as disponíveis através do handoff vertical. A investigação no domínio das redes de rádio cognitivo (CR) visa resolver o problema da escassez de espetro e da ineficiência da utilização do espetro através da transferência de espetro. Por conseguinte, as redes CR estão a merecer grande atenção por parte da comunidade sem fios. As redes sem fios heterogéneas com redes CR são designadas por redes CR heterogéneas, que facilitam simultaneamente o acesso dinâmico ao espetro e a seleção da rede. As redes CR heterogéneas enfrentam múltiplos desafios, como a disponibilidade de espetro variável no tempo e no local, tipos heterogéneos de nós e a seleção da melhor rede de entre as redes disponíveis. Por conseguinte, o handoff vertical em redes CR heterogéneas é uma forma natural de responder a estes desafios. Estes tipos de desafios complexos raramente são explorados na comunidade de investigação. Este livro apresenta um levantamento exaustivo e classificações de algoritmos de transferência vertical de redes sem fios heterogéneas e a acreditação destes algoritmos de transferência vertical para a melhor seleção de redes em redes CR heterogéneas.
