This article reviews recent progress in the study of IP-based mobility management technology for enhancing the mobility of cellular phones and other mobile nodes in fourth-generation mobile communications systems. The architecture and components of this management technology are described and some experimental and simulation results are presented. IP-based(More)
Abstract – Mobility support for mobile networks will be more important as the mobile Internet becomes increasingly popular. To support mobile networks, the concept of prefix scope binding (PSB) is being discussed in IETF; however, by only applying this concept to Mobile IPv6 (MIP), the problem of packet loss still remains. In this paper, we apply the PSB(More)
In the operation of hierarchical mobile IPv6 (HMIP) (H. Soliman, et al., 2003), a mobile node (MN) is supposed to send binding updates (BUs) to the home agent (HA) and a mobility anchor point (MAP); therefore, a MAP discovery protocol is needed to facilitate MN discovery of MAPs. Two protocols were previously proposed in (H. Soliman, et al., 2003) for MAP(More)
