Principais características do handoff da camada 3 em redes sem fio

Abstract

Initially mobility was possible only between similar networks. With the arrival of new devices that offer several types of wireless network interfaces, this mobility was extended which brought new problems, such as slow and loss of connection during the transition between networks. This transition, known as handoff, can be especially complex because of the peculiarities of the various interfaces. Thus, in this work a bibliographical revision of this situation is presented and of the several proposals presents in the literature with subjects that permeate the several nets Wireless, being analyzed among others: some important concepts for the understanding and discussing with larger emphasis the problems and the improvements presented recently in the studies of Handoff, and more specifically, what includes the handoff of the layer 3 of OSI model.
