Inter-subnet localized mobility support for host identity protocol

Host identity protocol (HIP) has security support to enable secured mobility and multihoming, both of which are essential for future Internet applications. Compared to end host mobility and multihoming with HIP, existing HIP-based micro-mobility solutions have optimized handover performance by reducing location update delay. However, all these mobility solutions are client-based mobility solutions. We observe that another fundamental issue with end host mobility and multihoming extension for HIP and HIP-based micro-mobility solutions is that handover delay can be excessive unless the support for network-based micro-mobility is strengthened. In this study, we co-locate a new functional entity, subnet-rendezvous server, at the access routers to provide mobility to HIP host. We present the architectural elements of the framework and show through discussion and simulation results that our proposed scheme has achieved negligible handover latency and little packet loss

A generic communication architecture for end to end mobility management in the Internet

The proliferation of laptops, cellular phones, and other mobile computing platforms connected to the Internet has triggered numerous research works into mobile networking. The increasingly dense set of wireless access networks that can be potentially accessed by mobile users open the door to an era of pervasive computing. However, the puzzle of wireless access networks that tends to become the natural access networks to the Internet pushes legacy“wireoriented” communication architectures to their limit. Indeed, there is a critical gap between the increasingly used stream centric multimedia applications and the incapacity of legacy communication stacks to insure the continuity of these multimedia sessions for mobile users. This paper proposes a generic communication architecture (i.e. not dedicated to a specific protocol or technology) that aims to fill the gap between the application layer continuity needs and the discontinuity of the communication service inherent to the physical layer of wireless mobile networks. This paper introduces an end to end communication architecture that preserves efficiently session continuity in the context of mobile and wireless networks. This architecture is mainly based on end to end mechanisms that could be integrated into a new generation reconfigurable transport protocol. The proposed contribution efficiently satisfies mobility requirements such as efficient location management, fast handover, and continuous connection support

Architecture for Mobile Heterogeneous Multi Domain Networks

Multi domain networks can be used in several scenarios including military, enterprize networks, emergency networks and many other cases. In such networks, each domain might be under its own administration. Therefore, the cooperation among domains is conditioned by individual domain policies regarding sharing information, such as network topology, connectivity, mobility, security, various service availability and so on. We propose a new architecture for Heterogeneous Multi Domain (HMD) networks, in which one the operations are subject to specific domain policies. We propose a hierarchical architecture, with an infrastructure of gateways at highest-control level that enables policy based interconnection, mobility and other services among domains. Gateways are responsible for translation among different communication protocols, including routing, signalling, and security. Besides the architecture, we discuss in more details the mobility and adaptive capacity of services in HMD. We discuss the HMD scalability and other advantages compared to existing architectural and mobility solutions. Furthermore, we analyze the dynamic availability at the control level of the hierarchy

A Survey on Handover Management in Mobility Architectures

This work presents a comprehensive and structured taxonomy of available techniques for managing the handover process in mobility architectures. Representative works from the existing literature have been divided into appropriate categories, based on their ability to support horizontal handovers, vertical handovers and multihoming. We describe approaches designed to work on the current Internet (i.e. IPv4-based networks), as well as those that have been devised for the "future" Internet (e.g. IPv6-based networks and extensions). Quantitative measures and qualitative indicators are also presented and used to evaluate and compare the examined approaches. This critical review provides some valuable guidelines and suggestions for designing and developing mobility architectures, including some practical expedients (e.g. those required in the current Internet environment), aimed to cope with the presence of NAT/firewalls and to provide support to legacy systems and several communication protocols working at the application layer

Secure Mobile IP with HIP Style Handshaking and Readdressing

Mobile IP allows the mobile node roaming into a new IP network without losing its connection with its peer. Mobile IPv6 is using Mobile IP with Route Optimizationto improve performance by avoiding the triangle routing and adopting Return Routability as a secure process for binding update. Host Identity Protocol (HIP) is an experimental security protocol which provides mobility management and multi-homing by its new namespace. Its architecture is similar to that of Mobile IP with Route Optimization. In this paper, we have introduced a Secure Mobile IP with HIP Style Handshaking and Readdressing (SMIP), which has stronger security, better performance and lower binding cost in binding update process compared with Mobile IPv6. The dependence of home agent in the new scheme is also shown dramatically decreased. The initiated scheme integrated the primary features of two completely different mobility management solutions and has set up a migration path from mobile-IP based solution to a public-key based solution in mobile IP network

Names, addresses and identities in ambient networks

Ambient Networks interconnect independent realms that may use different local network technologies and may belong to different administrative or legal entities. At the core of these advanced internetworking concepts is a flexible naming architecture based on dynamic indirections between names, addresses and identities. This paper gives an overview of the connectivity abstractions of Ambient Networks and then describes its naming architecture in detail, comparing and contrasting them to other related next-generation network architectures

HIP-based Handover Mechanism under MIH Architecture in Heterogeneous Wireless Networks

[[abstract]]In this paper, we offers a HIP-based vertical handover scheme under MIH architecture in heterogeneous wireless network. Many diversity wireless access technologies are offering in Next Generation Wireless Networks (NGWN). In NGWN, the integration of wireless access network will be accomplished by seamless handover which contains many challenges i.e. service mobility, vertical handover, common authentication, unified accounting/billing, security mechanisms, QoS and service provisioning, etc. Toward this direction, our research aims to provide a complete integration of heterogeneous network architecture and support a fit mobility management for network to seamless handover. We focus on simulation about vertical handover execution for WiMAX to WiFi scenario. Our idea can modify defects of Mobile IP and SIP. And it provides internet users always best connection. Moreover, we hope to contribute our research to beyond 4G wireless networks.[[notice]]補正完畢[[conferencetype]]國際[[conferencedate]]20110621~20110623[[booktype]]紙本[[booktype]]電子版[[iscallforpapers]]Y[[conferencelocation]]Gyeongju, Korea[[countrycodes]]KO

Host mobility management with identifier-locator split protocols in hierarchical and flat networks

Includes abstractIncludes bibliographical references.As the Internet increasingly becomes more mobile focused and overloaded with mobile hosts, mobile users are bound to roam freely and attach to a variety of networks. These different networks converge over an IP-based core to enable ubiquitous network access, anytime and anywhere, to support the provision of services, that is, any service, to mobile users. Therefore, in this thesis, the researcher proposed network-based mobility solutions at different layers to securely support seamless handovers between heterogeneous networks in hierarchical and flat network architectures

Distributed mobility management with mobile Host Identity Protocol proxy

The architectural evolution from hierarchical to flatter networks creates new challenges such as single points of failure and bottlenecks, non-optimal routing paths, scalability problems, and long handover delays. The cellular networks have been hierarchical so that they are largely built on centralized functions based on which their handover mechanisms have been built. They need to be redesigned and/or carefully optimized. The mobility extension to Host Identity Protocol (HIP) proxy, mobile HIP Proxy (MHP), provides a seamless and secure handover for the Mobile Host in the hierarchical network. However, the MHP cannot ensure the same handover performance in flatter network because the MHP has also utilized the features offered by the hierarchical architecture. This paper extends the MHP to distributed mobile HIP proxy (DMHP). The performance evaluation of the DMHP in comparison to MHP and other similar mobility solutions demonstrates that DMHP does indeed perform well in the flatter networks. Moreover, the DMHP supports both efficient multi-homing and handover management for many mobile hosts at the same time to the same new point of attachment
