  • Route optimization for Network mobility with tree-based care of address
    2009 15th Asia-Pacific Conference on Communications, 2009
    Co-Authors: Hyunduk Jung
    Abstract:

    Network mobility (NEMO) supports the movement of some part of the Network that a group of the mobile nodes (MNs) or the mobile routers (MRs) moves together. To support NEMO, the NEMO basic support protocol (NBSP) was proposed. In the nested mobile Network, however, the NBSP exhibits pinball routing problem. As the degree of nesting increase, the problem becomes more serious. In this paper, we propose a new NEMO management scheme using tree-based care of address (TCoA) and mobile Network Prefix (MNP). In proposed scheme, all the MRs belonging to the Root-MR in the nested mobile Network configure their care-of addresses (CoA) based on the MNP of Root-MR. It mitigates the pinball routing problem. Performance analysis indicates that proposed scheme can reduce end-to-end packet delay and handoff delay.

  • route optimization using collective binding update and mobile Network Prefix for nested mobile Networks
    ITC-CSCC :International Technical Conference on Circuits Systems Computers and Communications, 2008
    Co-Authors: Hyunduk Jung
    Abstract:

    Network Mobility (NEMO) supports the movement of some part of Network that a group of Mobile Nodes (MNs) or Mobile Routers (MRs) moves together. To support NEMO, the NEMO basic support protocol (NBSP) was proposed [1]. In the nested mobile Network, however, the NBSP exhibits pinball routing problem. The More nesting level, the problem becomes more serious. In this paper, we propose a new NEMO management scheme using Collective Binding Update (CBU) and Mobile Network Prefix (MNP). It can achieve route optimization and easy to implement. Performance analysis indicates that proposed scheme can reduce packet delay with low processing and signalling overheads.

  • Securing mobile Network Prefix provisioning for NEMO based vehicular Networks
    Mathematical and Computer Modelling, 2020
    Co-Authors: Jiefeng Terence Chen, Thierry Ernst
    Abstract:

    International audienceThe recently developed mobile Network Prefix provisioning (MNPP) enables a direct communication, i.e., Route Optimization (RO), between vehicular mobile routers (VMRs). However, without being secured, MNPP is vulnerable to various threats such as spoofing, replay, and wormhole attacks as well as location tracking. In this paper, possible threats to MNPP are identified with suggestions of security requirements. Then, three different security approaches (five different security mechanisms) for securing MNPP are introduced and compared

  • mnpp mobile Network Prefix provisioning for enabling route optimization in geographic vehicular Networks
    Ad Hoc & Sensor Wireless Networks, 2012
    Co-Authors: Manabu Tsukada, Thierry Ernst
    Abstract:

    Recent advances in the development of wireless vehicular Networks have become a cornerstone of IntelligentTransportation Systems (ITS).Vehicles support Network mobility (NEMO) can establish IPv6 data communications. However, due to characteristics of NEMO, data packets destined for equipments in an in-vehicle Network of a vehicle are not optimally transmitted to the vehicle equipments, e.g., arising of sub-optimal routing. In this paper, we introduce a mechanism for route optimization (RO) developed as part of the GeoNet project. The mechanism named as Mobile Network Prefix Provisioning (MNPP) enables a vehicle to provision its mobile Network Prefix (MNP) assigned to its equipments to neighbor vehicles so that the neighbor vehicles are able to send data packets directly to the equipments of the vehicle. Thanks to the direct communication between two vehicles, the packet delivery cost is significantly minimized.

  • mobile Network Prefix provisioning
    2009
    Co-Authors: Manabu Tsukada, Thierry Ernst
    Abstract:

    In the context of vehicular Networks for Intelligent Transportation Systems (ITS), vehicles that comprise in-vehicle Networks require to discover Mobile Network Prefixes (MNPs) of other vehicles in order to communicate with other vehicles or the roadside infrastructure on the same wireless link. This document proposes Mobile Network Prefix Provisioning (MNPP), a solution to advertise an MNP assigned to a vehicle to others in both a proactive or reactive fashion.

  • Network Prefix level traffic profiling characterizing modeling and evaluation
    Computer Networks, 2010
    Co-Authors: Hongbo Jiang, Zihui Ge, Jia Wang
    Abstract:

    A cardinal prerequisite for the proper and efficient management of a Network, especially an ISP Network, is to understand the traffic that it carries. Traffic profiling is a means to obtain knowledge of the traffic behavior. Previous work has been focusing on traffic profiling at the link level or the host level. However, Network Prefix-level traffic behaviors have not yet been investigated. In this paper, we are interested in empirical studies for finding and describing structural patterns in the overwhelming Network measurement data, as well as obtaining insight from it, with the expected traffic profiles potentially of interest to a broad range of applications such as Network management, traffic engineering, and data services. To this end, first, we derive a collection of features that characterize the Network Prefix-level aggregate traffic behaviors. Next we use a simple model to capture them on all features, and apply machine learning techniques to extract representative profiles from them. Finally, we collect Netflow measurements from the entire periphery of a Tier-1 ISP Network to empirically validate the simple model we proposed. Our extensive results show that nearly all Networks exhibit traffic characteristics that are stable over time. The derived traffic profiles provide valuable insights on the manifold behavioral patterns that cannot be easily learned otherwise.

  • hybrid home Network Prefix model for supporting inter technology handover in proxy mipv6 domains
    The Kips Transactions:partc, 2011
    Co-Authors: Yonggeun Hong, Sangheon Pack, Joosang Youn
    Abstract:

    Recently, with the popularity of smartphones, an interest in multi-Networking service through wireless multi-interface of a mobile node is increased. Also, wireless Networking technology for using wireless multi-interface has been studied. As the related work, in the IETF Netext WG, the extension of PMIPv6 protocol for multi-interface support is being discussed. Existing PMIPv6 protocol includes the functions for simultaneous access over multi-interfaces of a mobile node and inter-technology handover between multi-interfaces of the mobile node. However, in case of the existing protocol, the problem occurs when inter-technology handover is performed after simultaneous access on the PMIPv6 domain, this problem is the discontinuous of simultaneous connections. Therefore, the PMIPv6 Protocol cannot support flow based multi-homing service. In this paper, as a way to solve the problem, Hybrid Home Network Prefix scheme is proposed.

  • Analysis of the usage of a logical interface in PMIPv6
    2011
    Co-Authors: Yonggeun Hong, Joosang Youn, Tchanghee Hyun
    Abstract:

    A logical interface is used to hide the change of Network interface from the upper host IP layer and it also can be used for a multiple interfaces mobile node in PMIPv6 domain. In a MN point of view, the link-layer identifier of a logical interface can use same link-layer identifier of physical interface or a totally different link-layer identifier from them of physical interface. And in a LMA point of view, a LMA may acknowledge each physical interface or only a logical interface of a mobile node when a multiple interfaces mobile node utilizes a logical interface. If a LMA assigns multiple home Network Prefixes to a multiple interfaces mobile node with a logical interface, a logical interface has various usages of the multiple home Network Prefixes. As following general PMIPv6 operations described in RFC 5213, all multiple home Network Prefixes are shown to host IP layer. Also, the logical interface hides the existence of multiple home Network Prefixes and shows only one home Network Prefix to host IP layer. In this paper, we analyse various usages of a logical interface in a viewpoint of link-layer identifier and multiple home Network Prefixes and give some guidelines to implement.

  • hybrid home Network Prefix for multihoming in pmipv6
    2010
    Co-Authors: Joosang Youn, Yonggeun Hong
    Abstract:

    Proxy Mobile IPv6 (PMIPv6) supports multihoming where a mobile node can connect to a PMIPv6 domain through multiple interfaces for simultaneous access. However, for an inter-technology handoff, PMIPv6 does not allow simultaneous access since all the home Network Prefixes associated with one interface are associated with another interface of a mobile node. In this document, we propose a hybrid home Network Prefix assignment (HHNPA) scheme where both the static Prefix model and the dynamic Prefix model are used for simultaneous access. The static Prefix model is used within the general PMIPv6 domain. On the other hand, the dynamic Prefix model is employed for inter-technology handoff. That is, for IP session continuity during inter-technology handoff, a dynamic Prefix model is used on both interfaces.

  • Flow mobility support in PMIPv6
    2010
    Co-Authors: Yonggeun Hong, Tran Trung
    Abstract:

    To support flow mobility in PMIPv6, the Mobile Node's Home Network Prefix should be able to be shared across its attachments and the Network should support flow-based routing. This document specifies how to extend PMIPv6 to meet these requirements.

  • dynamic home Network Prefix assignment for multi homing in proxy mobile ipv6
    International Conference on Wireless Communications and Mobile Computing, 2010
    Co-Authors: Yonggeun Hong, Joosang Youn, Sangheon Pack
    Abstract:

    Proxy Mobile IPv6 (PMIPv6) supports multi-homing where a mobile node can connect to a PMIPv6 domain through multiple interfaces for simultaneous access. However, for an interface handoff, PMIPv6 does not allow simultaneous access since all the home Network Prefixes associated with one interface are associated with another interface of a MN. In this paper, we propose a dynamic home Network Prefix assignment (DHNPA) scheme where both the fixed Prefix model and shared Prefix model are used for simultaneous access. Simulation results show that the DHNPA scheme can achieve simultaneous access and provide the information for handoff indication in multi-homing scenario.
