When a mobile network dynamically changes its point of attachment to the Internet, the various types of movements by a mobile router require handovers, and network mobility (NEMO) is concerned with the management of this movement of mobile networks. Accordingly, this paper investigates the mobile router movement patterns in NEMO network environments, and defines fast hierarchical NEMO handover scenarios based on classified movement patterns. Due to unexpected link breakdowns during the handover procedure, the NEMO handover requires additional latency and packet delivery costs depending on when the breaks occur. For the various handover failure cases, it is also essential to analyze these overhead costs to evaluate and compare the performance of a fast handover. In this paper, the overheads associated with a NEMO fast handover include the latency, buffering cost, and packet loss cost, all of which are formulated based on a timing diagram.Keywords Network mobility (NEMO) · Fast handover (FMIPv6) · Hierarchical MIPv6 (HMIPv6)

“…In the year 2000, Motorola's Paris laboratory proposed to extend MIPv6 by establishing a tunnel between the HA and the Mobile Network Gateway, and on behalf of all hosts of the subnetwork, Mobile Network Gateway creates and updates bindings of location with the HA [17]. In the year 2001, NTT DoCoMo proposed to extend MIPv6 by dynamic exchange routing information between mobile router and HA when this mobile router moves to a network attachment point [18].…”

Mobility Management

This chapter focuses on basic concept and method of mobility management solutions at the network layer. Typical protocols such as Mobile IP (MIP), Dual Stack Mobile IP, and Proxy Mobile IP are introduced, as well as related key technologies. The support of IP flow mobility, network mobility solutions, and security mechanism related to mobility management at network layer are also briefly described. OverviewAt early age of Internet, hosts (e.g., mainframe computers, desktop computers, printers) are connected to the network via Internet Protocol (IP) [1]-based wired links, e.g., via Ethernet, cable, and xDSL. Due to the development of wireless communication, more and more hosts (e.g., laptop, tablet) require communication during or after movement. Lots of protocols of different layers and solutions which support host mobility appeared. Network-layer mobility management technology based on IP protocol, is featured by its agnostic to the underlying access technologies. It is also transparent to the upper-layer protocols and applications, and has become the focus of mobility management research.The Internet is designed for fixed or wired networks, where each host is assigned one IP address or more IP addresses (e.g., router) via either static configurations or dynamic interaction with network (e.g., via Dynamic Host Configuration Protocol (DHCP) [2]). However, exactly what IP address could be assigned to a host is based on network topology, rather than based on host's identity. Actually, an IP address actually identifies a network attachment point or an interface to the network, rather than the host itself. The host has fixed network attachment point, and the corresponding IP address could be considered as this host's identity as well.If a host changes its network attachment point, it will be assigned a new IP address. Thus, ongoing communication based on IP would be interrupted due to the following reasons: (a) IP packets destined to the host's old IP address arrived at old Some solutions have been proposed to resolve these problems. One of them is to update new IP address with corresponding part as soon as possible. However, this solution does not hide host mobility to upper-layer protocols and applications. For example, all application that is based on Transmission Control Protocol (TCP) [3] that requires fixed IP address during the lifetime of the TCP connection could not guarantee service continuity. Another proposal is to deploy host-specific routing within whole IP network. In this solution, the IP address allocated by host's home network would keep unchanged even the host has moved to another network attachment point. All routers within the network update their routing table with this host address, that is, a host-specific routing entry is created within the whole network. The signaling cost for host-specific route is high for a host. Considering that more and more hosts need mobility support, this solution would introduce huge routing update signaling. That is, this solution has poor scalability and efficienc...

“…Secondly, over mobile 1Pv6 [16,17], scalable hybrid PKl frameworks based on hierarchical, mesh and bridge CA trust model [1S,19] is proposed. Thirdly, Our scheme combines dynamic password 120-221 with public-key mechanism so that ME without certificate can be authenticated with low computational loads even outside home networks and can't repudiate its service either, Thus the key management is more convenient and feasible.…”

Abstmct-4Gmobile communication systems focus on seamtessly integrating the existing wireless technologies and providing great flexibility and mobility which complex the sccurity problem in turn. In this paper security policy including authentication, authorization, account and audit (AAAA) is discusscd according to the features of 4G systems. Meanwhile the security architecture scenario based on hybrid PKI trust model and mobile IPv6 is proposed. Over this architecture a novel hybrid authentication and key agreemcnt scheme that associates dynamic password with public-key mechadism is presented to provide lightweight authentication and non-repudiation service. Compare with other architectures and protocols, our scheme is mort flexible and convenient to support globe mobility with low computational power and secure communication. So it is very suitable for 4G mobile communication systems.
