  • Mobility Support in Ipv4/v6 Network
    Advances in Intelligent and Soft Computing, 2020
    Co-Authors: Zheng Xiang, Zhengming Ma
    Abstract:

    IETF has specified Mobile Ipv4 and Mobile IPv6 in RFC3344 and RFC3775 respectively, but not yet discussed Mobile Ipv4/v6 in any published RFC. This paper proposes a solution to Mobile Ipv4/v6 problems. In the solution, a gateway called Mobile Ipv4/v6 translation gateway (MIpv4/v6-TG) is introduced to bridge between Ipv4 network and IPv6 network, which is made up of a traditional NAT-PT gateway and a Mobile IP application level gateway (MIP-ALG) built upon the NAT-PT gateway. MIP-ALG maintains MIP table, a data structure, which is formed by entries. We use the MIP table to realize the communication between the Ipv4 entities and the IPv6 entities. The creation, usage and update processes of MIP table are described in this paper. Through the experiment we find that the MIpv4/v6-TG can realize the basic communication in Ipv4/v6 mixed network. The measurement of performance test proves the solution’s efficiency. And it can work compatibly with RFC3344 and RFC3775.

  • Mobile Ipv4 Challenge/Response Extensions (Revised)
    2020
    Co-Authors: Pat Calhoun, Jayshree Bharatia, Charles E Perkins
    Abstract:

    Mobile IP, as originally specified, defines an authentication extension (the Mobile-Foreign Authentication extension) by which a Mobile node can authenticate itself to a foreign agent. Unfortunately, that extension does not provide the foreign agent any direct guarantee that the protocol is protected from replays and does not allow for the use of existing techniques (such as Challenge Handshake Authentication Protocol (CHAP)) for authenticating portable computer devices. In this specification, we define extensions for the Mobile IP Agent Advertisements and the Registration Request that allow a foreign agent to use a challenge/response mechanism to authenticate the Mobile node. Furthermore, this document updates RFC 3344 by including a new authentication extension called the Mobile-Authentication, Authorization, and Accounting (AAA) Authentication extension. This new extension is provided so that a Mobile node can supply credentials for authorization, using commonly available AAA infrastructure elements. This authorization-enabling extension MAY co-exist in the same Registration Request with authentication extensions defined for Mobile IP Registration by RFC 3344. This document obsoletes RFC 3012.

  • Mobile Ipv4 Fast Handovers
    2007
    Co-Authors: Rajeev Koodli, Charles E Perkins
    Abstract:

    The Mobile IPv6 fast handover document [2] specifies a protocol to improve latency and packet loss resulting from Mobile IPv6 handover operations. This document adapts the protocol for Ipv4 networks to improve performance over Mobile Ipv4 operations, including processing of Agent Advertisements, new Care of Address acquisition and Registration Request and Reply. However, operation without Foreign Agent function at a router is also feasible. In addition, the protocol may be used transparently on hosts which do not support Mobile IP, but with limited movement across subnets. Using the concepts outlined in [2], this document also addresses movement detection, IP address configuration and location update latencies during a handover. For reducing the IP address configuration, the document currently proposes that the new CoA is always made to be the new access router's IP address. Additional mechanisms may be defined in the future versions of this document.

  • foreign agent error extension for Mobile Ipv4
    RFC, 2006
    Co-Authors: Charles E Perkins
    Abstract:

    This document specifies a new extension for use by Foreign Agents operating Mobile IP for Ipv4. The new extension option allows a foreign agent to supply an error code without disturbing the data supplied by the Home Agent within the Registration Reply message. In this way, the Mobile node can verify that the Registration Reply message was generated by the Home Agent even in cases where the foreign agent is required by protocol to insert new status information into the Registration Reply message.

  • diameter Mobile Ipv4 application
    RFC, 2005
    Co-Authors: Peter J Mccann, Charles E Perkins
    Abstract:

    This document specifies a Diameter application that allows a Diameter server to authenticate, authorize and collect accounting information for Mobile Ipv4 services rendered to a Mobile node. Combined with the Inter-Realm capability of the base protocol, this application allows Mobile nodes to receive service from foreign service providers. Diameter Accounting messages will be used by the foreign and home agents to transfer usage information to the Diameter servers. [STANDARDS-TRACK]

  • Mobile Ipv4 secure access to home networks
    2006
    Co-Authors: J.a. Copeland, Jin Tang
    Abstract:

    With the fast development of wireless networks and devices, Mobile IP is expected to be used widely so that Mobile users can access the Internet anywhere, anytime without interruption. However, some problems, such as firewall traversal and use of private IP addresses, restrict use of Mobile IP. The objective of this thesis is to design original schemes that can enable a Mobile node at abroad to access its home network as well as the Internet securely and that can help Mobile IP to be used widely and commercially. Our solutions are secure, efficient, and scalable. They can be implemented and maintained easily. In this thesis, we mainly consider Mobile Ipv4, instead of Mobile IPv6. Three research topics are discussed. In each topic, the challenges are investigated and the new solutions are presented. The first research topic solves the firewall traversal problems in Mobile IP. A Mobile node cannot access its firewall-protected home network if it fails the authentication by the firewall. We propose that an IPsec tunnel be established between the firewall and the foreign agent for firewall traversal and that an IPsec transport security association be shared by the Mobile node and a correspondent node for end-to-end security. The second topic researches further on firewall traversal problems and investigates the way of establishing security associations among network entities. A new security model and a new key distribution method are developed. With the help of the security model and keys, the firewall and the relevant network entities set up IPsec security associations to achieve firewall traversal. A Mobile node from a private home network cannot communicate with other hosts with its private home address when it is visiting a public foreign network. A novel and useful solution is presented in the third research topic. We suggest that the Mobile node use its Network Access Identifier (NAI) as its identification and obtain a public home address from its home agent. In addition, a new tunnel between the Mobile node and its home agent is proposed.

  • Mobile Ipv4 secure firewall traversal with deployment of foreign agents
    IEEE Wireless Communications and Networking Conference 2005, 2005
    Co-Authors: Jin Tang, J.a. Copeland
    Abstract:

    Currently Mobile IP can enable Mobile users to enjoy seamless roaming. However, if home networks are firewall-protected, Mobile users can not access their home networks without successful authentication. So Mobile users are out of contact with their home agents and then get lost to some extent. In this paper, we consider the case that, in Mobile Ipv4, a Mobile node away from home obtains a care-of address from a foreign agent and communicates with its home agent and a correspondent node that are both behind the firewall of the home network. Our solution can achieve successful firewall traversal as well as end-to-end security by applying IPsec mechanisms on network entities. It does not require any modification of protocols and network entities. Besides, if foreign agents are deployed hierarchically, the security associations do not need to be renegotiated whenever a Mobile node changes its network attachment point.

  • wimax forum 3gpp2 proxy Mobile Ipv4
    RFC, 2010
    Co-Authors: Kent Leung
    Abstract:

    Mobile Ipv4 is a standard mobility protocol that enables an Ipv4 device to move among networks while maintaining its IP address. The Mobile device has the Mobile Ipv4 client function to signal its location to the routing anchor, known as the Home Agent. However, there are many Ipv4 devices without such capability due to various reasons. This document describes Proxy Mobile Ipv4 (PMIpv4), a scheme based on having the Mobile Ipv4 client function in a network entity to provide mobility support for an unaltered and mobility-unaware Ipv4 device. This document also describes a particular application of PMIpv4 as specified in the WiMAX Forum and another application that is to be adopted in 3GPP2. This document is not an Internet Standards Track specification; it is published for informational purposes.

  • Ipv4 Network Mobility (NEMO) Basic Support Protocol
    2006
    Co-Authors: Kent Leung
    Abstract:

    This document describes the support of Mobile Networks, as defined in Mobile Ipv4, by the Mobile Router and Home Agent. A Mobile Router is responsible for the mobility of one or more network segments or subnets moving together. The Mobile Router hides its mobility from the nodes on the Mobile network. The nodes on the Mobile Network may be fixed in relationship to the Mobile Router and may not have any mobility function. Extensions to Mobile Ipv4 are introduced to support Mobile Networks.
