Wireless technologies have rapidly evolved in recent years. IEEE 802.11 jointly with Mobile IP provides mobility to the internet. The most critical part of this technology (IEEE 802.11 and Mobile IP) is the handover. During this time the connection may be interrupted and packets can be lost or delayed. These issues makes difficult to run VoIP applications in a mobile environment. In this paper we propose an extension to the Mobile IPv6 protocol using a multihomed mobile node and a cross-layer design. We compare our proposal with Fast Handovers for Mobile IPv6 and Hierarchical Mobile IPv6.
