ABSTRACT: Mobile IP has been defined by Third Generation Partnership Project 2(3GPP2) to be the mobility solution for the next generation cellular networks. The Mobile IP related issues therefore become important and popular. Mobile IP provides the Mobile Node (MN) the ability of roaming around a foreign domain. An MN needs to register with its Home Agent (HA) through the attached Foreign Agent (FA) when it roams to a foreign domain. If the frequency of MN handoffs is high and the foreign domain is too far from the home domain, the delay of the registration will be significant. The hierarchical foreign agent management is proposed to solve this problem. However, the Gateway Foreign Agent (GFA) will become a bottleneck when it serves too many MNs. In this paper, we propose a mobility management with distributed architecture to solve the bottleneck problem. We also present some simulation results to support our scheme by using NS2.International Journal of Network Security. 01/2007;
Conference Proceeding: Integrated Multi-layer Registration Combining SIP with Mobile IP Schemes.[show abstract] [hide abstract]
ABSTRACT: Mobile communications will be the major applications of next-generation Internet. The users may access the mobile services using handheld devices anywhere and anytime. Therefore, mobility management will play a significant role in providing mobile multimedia services. Both MIP and SIP have been proposed to solve the IP mobility issues. For the multimedia application such as VoIP, SIP has been studied and widely deployed recently. To process various data with both MIP and SIP protocols, it is necessary to design an efficient multi-layer registration scheme for mobility management and multimedia services. In this paper, we propose an integrated scheme to improve the registration efficiency for mobile nodes carrying out both MIP and SIP protocols. The number of registration message as well as the registration delay will be reduced by using the proposed integrated multi-layer registration scheme.Wireless Algorithms, Systems, and Applications, First International Conference, WASA 2006, Xi'an, China, August 15-17, 2006, Proceedings; 01/2006
