Proxy Mobile IPv6(PMIPv6) is a network-based mobility management protocol to support mobility for IPv6 nodes without host involvement. In PMIPv6, the Mobile Access Gateway(MAG) incurs a high signaling cost to update the location of a mobile node to the remote local mobility anchor(LMA) if the mobile node moves frequently. This increases network overhead on the LMA, wastes network resources, and lengthens...
PMIPv6 has been proposed in network-based localized mobility management (NetLMM) of IETF. The PMIPv6 copes with the disadvantages of client-based mobility technology by utilizing network-based mobility technology in which the handover function of a mobile node (MN) is replaced by a router. However, the PMIPv6 has the critical problem that inter-cell handover is not supported. In order to support the...
One of the most important issues in wireless and mobile communication technologies is the mobility management when a mobile node moves between different access networks. Many alternative ways to realize mobility management have been proposed on different layers. In this paper we discuss the vertical handoff behavior when a mobile node moves from IEEE 802.11 network to IEEE 802.16 network and vice...
The network-based mobility management scheme, proxy mobile IPv6 (PMIPv6), was recently proposed by the IETF NetLMM WG. In a PMIPv6 domain, an mobile node (MN) mobility can be provided without any mobility protocol stack, such as Mobile IPv6 (MIPv6). However, since the PMIPv6 protocol was only designed for local mobility management, MN mobility cannot be supported outside a PMIPv6 domain. Accordingly,...
