Design of multi-homing architecture for mobile hosts

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.This thesis proposes a new multi-homing mobile architecture for future heterogeneous network environment. First, a new multi-homed mobile architecture called Multi Network Switching enabled Mobile IPv6 (MNS-MIP6) is proposed which enables a Mobile Node (MN) having multiple communication paths between itself and its Correspondent Node (CN) to take full advantage of being multi-homed. Multiple communication paths exist because MN, CN, or both are simultaneously attached to multiple access networks. A new sub layer is introduced within IP layer of the host’s protocol stack. A context is established between the MN and the CN. Through this context, additional IP addresses are exchanged between the two. Our MNS-MIP6 architecture allows one communication to smoothly switch from one interface/communication path to another. This switch remains transparent to other layers above IP. Second, to make communication more reliable in multi-homed mobile environments, a new failure detection and recovery mechanism called Mobile Reach ability Protocol (M-REAP) is designed within the proposed MNS-MIP6 architecture. The analysis shows that our new mechanism makes communication more reliable than the existing failure detection and recovery procedures in multi-homed mobile environments. Third, a new network selection mechanism is introduced in the proposed architecture which enables a multi-homed MN to choose the network best suited for particular application traffic. A Policy Engine is defined which takes parameters from iv the available networks, compares them according to application profiles and user preferences, and chooses the best network. The results show that in multi-homed mobile environment, load can be shared among different networks/interfaces through our proposed load sharing mechanism. Fourth, a seamless handover procedure is introduced in the system which enables multi-homed MN to seamlessly roam in a heterogeneous network environment. Layer 2 triggers are defined which assist in handover process. When Signal to Noise Ratio (SNR) on a currently used active interface becomes low, a switch is made to a different active interface. We show through mathematical and simulation analysis that our proposed scheme outperforms the existing popular handover management enhancement scheme in MIPv6 networks namely Fast Handover for MIPv6 (FMIPv6). Finally, a mechanism is introduced to allow legacy hosts to communicate with MNS-MIP6 MNs and gain the benefits of reliability, load sharing and seamless handover. The mechanism involves introducing middle boxes in CN’s network. These boxes are called Proxy-MNS boxes. Context is established between the middle boxes and a multi-homed MN

End-to-end mobility for the internet using ILNP

This work was partially funded by the Government of Thailand through a PhD scholarship for Dr Phoomikiattisak.As the use of mobile devices and methods of wireless connectivity continue to increase, seamless mobility becomes more desirable and important. The current IETF Mobile IP standard relies on additional network entities for mobility management, can have poor performance, and has seen little deployment in real networks. We present a host-based mobility solution with a true end-to-end architecture using the Identifier-Locator Network Protocol (ILNP). We show how the TCP code in the Linux kernel can be extended allowing legacy TCP applications that use the standard C sockets API to operate over ILNP without requiring changes or recompilation. Our direct testbed performance comparison shows that ILNP provides better host mobility support than Mobile IPv6 in terms of session continuity, packet loss, and handoff delay for TCP.Publisher PDFPeer reviewe

Mobility management across converged IP-based heterogeneous access networks

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University, 8/2/2010.In order to satisfy customer demand for a high performance “global” mobility service, network operators (ISPs, carriers, mobile operators, etc.) are facing the need to evolve to a converged “all-IP” centric heterogeneous access infrastructure. However, the integration of such heterogeneous access networks (e.g. 802.11, 802.16e, UMTS etc) brings major mobility issues. This thesis tackles issues plaguing existing mobility management solutions in converged IP-based heterogeneous networks. In order to do so, the thesis firstly proposes a cross-layer mechanism using the upcoming IEEE802.21 MIH services to make intelligent and optimized handovers. In this respect, FMIPv6 is integrated with the IEEE802.21 mechanism to provide seamless mobility during the overall handover process. The proposed solution is then applied in a simulated vehicular environment to optimize the NEMO handover process. It is shown through analysis and simulations of the signalling process that the overall expected handover (both L2 and L3) latency in FMIPv6 can be reduced by the proposed mechanism by 69%. Secondly, it is expected that the operator of a Next Generation Network will provide mobility as a service that will generate significant revenues. As a result, dynamic service bootstrapping and authorization mechanisms must be in place to efficiently deploy a mobility service (without static provisioning), which will allow only legitimate users to access the service. A GNU Linux based test-bed has been implemented to demonstrate this. The experiments presented show the handover performance of the secured FMIPv6 over the implemented test-bed compared to plain FMIPv6 and MIPv6 by providing quantitative measurements and results on the quality of experience perceived by the users of IPv6 multimedia applications. The results show the inclusion of the additional signalling of the proposed architecture for the purpose of authorization and bootstrapping (i.e. key distribution using HOKEY) has no adverse effect on the overall handover process. Also, using a formal security analysis tool, it is shown that the proposed mechanism is safe/secure from the induced security threats. Lastly, a novel IEEE802.21 assisted EAP based re-authentication scheme over a service authorization and bootstrapping framework is presented. AAA based authentication mechanisms like EAP incur signalling overheads due to large RTTs. As a result, overall handover latency also increases. Therefore, a fast re-authentication scheme is presented which utilizes IEEE802.21 MIH services to minimize the EAP authentication process delays and as a result reduce the overall handover latency. Analysis of the signalling process based on analytical results shows that the overall handover latency for mobility protocols will be approximately reduced by 70% by the proposed scheme

Control mechanisms for mobile terminals in heterogeneous access technology environments

Internet is evolving to become mobile and ubiquitous. As a consequence, there is a trend towards a diversification of the access technologies, as it can be seen with the recent appearance of wireless technologies such as WiFi or UMTS and the future deployment of WiMAX. Following these new opportunities, multi-technology terminals able to connect to the Internet through different technologies are appearing in the market. In this scenario, users start to demand new solutions able to use these new technologies in a transparent way from the user point of view. Foreseeing this demand, the IEEE started developing the specification IEEE 802.21, which enables multi-technology terminals to handover from one technology to another in a transparent way for the user. This specification has not yet being finished, and its deployment requires from the research community to analyze how to integrate it in current networks, how to achieve maximum benefit from its possibilities, and how to configure its parameters. In this thesis we propose control mechanisms for IP terminals to i) support efficient handovers in multi-technology environments applying the 802.21 framework and ii) allow the use of several interfaces and/or multiple providers by the terminals to improve the failure robustness of their communications. These mechanisms are focused in the terminal, although we also provide details on how to integrate IEEE 802.21 into nowadays operator's networks. The contributions of this thesis are threefold. In the first place the integration of 802.21 into terminals has been studied, focusing on the configuration of the parameters required to decide when to perform a handover in the case when the handover is initiated by the terminal. This analysis has also been done taking into account variables such as the terminal speed and the delay of the links. In the second place, we have studied how to introduce the Network Controlled Handover concept, using 802.21, into the network, including the possibility of the handover being initiated by the network. We have analyzed which are the main benefits of this approach and proposed and validated an implementation of this concept in 802.21. In third place we have analyzed a protocol, REAP, under development in the IETF, which allows terminals to detect and recover from failures in the links used in their communications. We have focused in the analytical characterization of the time required to detect a failure, since this parameter is crucial for the application's behavior. The applications should be able to cope with a failure without being disrupted by it. Through the analytical study performed, the REAP protocol can be properly configured to achieve a target recovery time. All the proposed mechanisms have been validated through simulation, using several tools such as OPNET, OMNET++ and MatlabLas tecnologías de acceso están evolucionando hacia un perfil móvil y ubicuo. Así mismo se está produciendo una diversificación en las tecnologías de acceso disponibles, con la proliferación de tecnologías inalámbricas como WiFi o UMTS y el despliegue próximo de WiMAX. Con la diversificación en el acceso aparecen también los primeros terminales multi-tecnología, capaces de utilizar diferentes redes simultáneamente. En este escenario, los usuarios empiezan a demandar soluciones y servicios capaces de utilizar estas tecnologías de forma transparente al usuario. Anticipándose a esta demanda, el IEEE comenzó la estandarización de la especificación 802.21 que permitirá a terminales multi-tecnología la posibilidad de realizar traspasos transparentes entre diferentes redes de acceso. Dicha especificación todavía no ha sido completada y su despliegue requiere la investigación de cómo integrarla en las redes actuales, cómo obtener el máximo beneficio de las posibilidades que presenta, así como de la configuración de sus parámetros. En la presente Tesis Doctoral proponemos una arquitectura que dota a terminales IP de mecanismos de control para i) soportar movilidad eficiente en entornos multi-tecnología en el marco de 802.21 y ii) permitir el uso de múltiples interfaces y/o proveedores con el objetivo de mejorar la robustez ante fallos en las comunicaciones. Dicha arquitectura se centra en el terminal aunque también se aportan detalles de cómo introducir las modificaciones requeridas por IEEE 802.21 en las redes de los operadores. Las contribuciones realizadas son varias. En primer lugar se ha estudiado la integración de IEEE 802.21 en un terminal, centrándonos en la configuración de los parámetros utilizados para determinar el momento del traspaso cuando éste es iniciado por el terminal. En segundo lugar se estudió cómo introducir, usando IEEE 802.21, el concepto de traspaso controlado por la red incluyendo la posibilidad de que la propia red sea la iniciadora del traspaso, analizando sus beneficios y aportando una propuesta de implementación dentro de IEEE 802.21. En tercer lugar analizamos un protocolo, REAP, que se está desarrollando dentro del IETF para permitir, desde los terminales, la detección y recuperación frente a fallos en los enlaces usados en sus comunicaciones. Dentro de este bloque nos centramos en la caracterización analítica del tiempo requerido para detectar un fallo ya que este parámetro es de vital importancia para el funcionamiento de las aplicaciones, que deben poder sobrevivir a un fallo sin verse completamente interrumpidas por él. Con el estudio analítico realizado es posible configurar REAP para alcanzar un tiempo determinado de recuperación ante fallo. Todos los mecanismos propuestos han sido validados mediante simulación empleando diversas herramientas como OPNET, OMNET++ y Matla

Gestion de la mobilité dans les réseaux denses de cinquième génération (5G)

Les réseaux de communications mobiles ont connu de profondes avancées technologiques au cours des deux dernières décénnies. La croissance du nombre d’abonnés mobiles ainsi que l’accès à des forfaits de données illimitées, souvent à des tarifs préférentiels, ont engendré une demande de bande passante, de vidéo et de données en forte croissance. Ces progrès significatifs ont favorisé le déploiement de nouveaux services et de nouveaux cas d’utilisation tels que l’Internet-des-objets (IoT), la réalité augmentée et virtuelle, les réseaux de villes intelligentes, les véhicules autonomes et l’automatisation industrielle. Aux technologies existantes, s’ajouteront de nouveaux modes de communication dans le but de répondre à plusieurs cas d’utilisation des réseaux mobiles qui sont encore difficiles à satisfaire à ce jour. Le résultat à long terme de cette nouvelle tournure dans le monde de la réseautique mobile est désigné sous le vocable de réseaux de cinquième génération (5G). Au-delà du déploiement d’applications avancées, les réseaux 5G offriront de nouvelles opportunités de revenus aux fournisseurs de services lorsqu’ils seront combinés aux fonctionnalités avancées telles que l’analyse de données, l’apprentissage automatique et à l’intelligence artificielle. Dans ce contexte, un large consensus est aujourd’hui établit sur la nécessité d’accroître la capacité du réseau par un déploiement massif de cellules de petite taille (Small Cell, SCs), d’un rayon de couverture réduit et à faible puissance. On parle alors d’une ultra-densification du réseau dont le but essentiel est de favoriser la proximité des points d’accès des utilisateurs finaux. Cependant, la densification du réseau implique des relèves fréquentes des usagers mobiles (MNs) entre les SCs et les zones de service. En effet, le rayon de couverture réduit des SCs rend plus complèxe la phase de sélection des relèves en plus d’accroître la fréquence de celles-ci. Ces relèves entraînent des dégradations, des perturbations et des déconnexions qui peuvent entraver l’objectif d’un accès transparent aux services du réseau. En outre, la fréquence des relèves engendre une latence et une charge de signalisation élevées dans le reseau. De plus, l’omniprésence d’applications temps réel exige une latence faible du réseau. Dans ce contexte, la gestion de la mobilité demeure encore un enjeux et il s’avère donc indispensable de concevoir de nouveaux protocoles de gestion de la mobilité capables répondre aux exigences de performances strictes des réseaux 5G.----------ABSTRACT : Mobile communications networks have experienced tremendous technological advances in the last two decades. The growth of the number of mobile subscribers and access to unlimited data plans, often at very affordable prices, have led to an increased demand for bandwidth, video and high-growth data. These significant advances have facilitated the deployment of new services and use cases such as Internet-of-things (IoT), augmented and virtual reality, smart city networks, autonomous vehicles, and industrial automation. On top of the existing technologies, new communication modes will arise to respond to several uses cases of mobile systems that are still difficult to meet today. The long-term result of this new trend in the world of mobile networking gives birth to a new paradigm called the fifth generation networks (5G). Beyond deploying advanced applications, 5G networks will offer new revenue opportunities to service providers, when combined with advanced features such as data analytics, machine learning, and artificial intelligence. In this context, a broad consensus is now established on the need to increase the network capacity through a massive deployment of small cells (Small Cell, SCs), with reduced coverage and low power. This requirement led to the ultra-densification of the network whose primary purpose is to promote the proximity of access points to the end-users. However, the densification of the cellular networks involves many mobile nodes (MNs) going through several handovers between the SCs and the service areas. The shorter SC’s radius makes the handover selection phase more complex while increasing its frequency. These handovers lead to service disruptions and disconnections that may hinder the provision of seamless mobility of network services. Moreover, the frequency of the handovers generates a high latency and signaling load in the network. Besides, the ubiquity of real-time applications requires low network latency. In this context, mobility management is still an issue, and it is, therefore, essential to design new mobility management protocols that can meet the stringent performance requirements of 5G networks

IEEE 802.21 in heterogeneous handover environments

Mestrado em Engenharia de Computadores e TelemáticaO desenvolvimento das capacidades tecnológicas dos terminais móveis, e das infra-estruturas que os suportam, potenciam novos cenários onde estes dispositivos munidos com interfaces de diferentes tecnologias vagueiam entre diferentes ambientes de conectividade. É assim necessário providenciar meios que facilitem a gestão de mobilidade, permitindo ao terminal ligar-se da melhor forma (i.e., optando pela melhor tecnologia) em qualquer altura. A norma IEEE 802.21 está a ser desenvolvida pelo Institute of Electrical and Electronics Engineers (IEEE) com o intuito de providenciar mecanismos e serviços que facilitem e optimizem handovers de forma independente da tecnologia. A norma 802.21 especifica assim um conjunto de mecanismos que potenciarão cenários como o descrito acima, tendo em conta a motivação e requerimentos apresentados por arquitecturas de redes futuras, como as redes de quarta geração (4G). Esta dissertação apresenta uma análise extensiva da norma IEEE 802.21, introduzindo um conjunto de simulações desenvolvidas para estudar o impacto da utilização de mecanismos 802.21 em handovers controlados por rede, numa rede de acesso mista composta por tecnologias 802.11 e 3G. Os resultados obtidos permitiram verificar a aplicabilidade destes conceitos a ambientes de próxima geração, motivando também uma descrição do desenho de integração de mecanismos 802.21 a arquitecturas de redes de quarta geração. ABSTRACT: The development of the technological capabilities of mobile terminals, and the infra-structures that support them, enable new scenarios where these devices using different technology interfaces roam in different connectivity environments. This creates a need for providing the means that facilitate mobility management, allowing the terminal to connect in the best way possible (i.e., by choosing the best technology) at any time. The IEEE 802.21 standard is being developed by the Institute of Electrical and Electronics Engineers (IEEE) to provide mechanisms and services supporting Media Independent Handovers. The 802.21 standard specifies a set of mechanisms that enable scenarios like the one described above, considering the motivation and requirements presented by future network architectures, such as the ones from fourth generation networks (4G). This thesis presents an extensive analysis of the IEEE 802.21 standard, introducing a set of simulations developed for studying the impact of using 802.21 mechanisms in network controlled handovers, in a mixed access network composed of 802.11 and 3G technologies. The obtained results allow the verification of the applicability of these concepts into next generation environments, also motivating the description of the design for integration of 802.21 mechanisms to fourth generation networks

Connecting Vehicles to the Internet - Strategic Data Transmission for Mobile Nodes using Heterogeneous Wireless Networks

With the advent of autonomous driving, the driving experience for users of connected vehicles changes, as they may enjoy their travel time with entertainment, or work productively. In our modern society, both require a stable Internet access. However, future mobile networks are not expected to be able to satisfy application Quality of Service (QoS) requirements as needed, e.g. during rush hours. To address this problem, this dissertation investigates data transmission strategies that exploit the potential of using a heterogeneous wireless network environment. To this end, we combine two so far distinct concepts, firstly, network selection and, secondly, transmission time selection, creating a joint time-network selection strategy. It allows a vehicle to plan delay-tolerant data transmissions ahead, favoring transmission opportunities with the best prospective flow-network matches. In this context, our first contribution is a novel rating model for perceived transmission quality, which assesses transmission opportunities with respect to application QoS requirement violations, traded off by monetary cost. To enable unified assessment of all data transmissions, it generalizes existing specialized rating models from network selection and transmission time selection and extends them with a novel throughput requirement model. Based on that, we develop a novel joint time-network selection strategy, Joint Transmission Planning (JTP), as our second contribution, planning optimized data transmissions within a defined time horizon. We compare its transmission quality to that of three predominant state-of-the-art transmission strategies, revealing that JTP outperforms the others significantly by up to 26%. Due to extensive scenario variation, we discover broad stability of JTP reaching 87-91% of the optimum. As JTP is a planning approach relying on prediction data, the transmission quality is strongly impaired when executing its plans under environmental changes. To mitigate this impact, we develop a transmission plan adaptation as our third contribution, modifying the planned current transmission online in order to comply with the changes. Even under strong changes of the vehicle movement and the network environment, it sustains 57%, respectively 36%, of the performance gain from planning. Finally, we present our protocol Mobility management for Vehicular Networking (MoVeNet), pooling available network resources of the environment to enable flexible packet dispatching without breaking connections. Its distributed architecture provides broad scalability and robustness against node failures. It complements control mechanisms that allow a demand-based and connection-specific trade-off between overhead and latency. Less than 9 ms additional round trip time in our tests, instant handover and 0 to 4 bytes per-packet overhead prove its efficiency. Employing the presented strategies and mechanisms jointly, users of connected vehicles and other mobile devices can significantly profit from the demonstrated improvements in application QoS satisfaction and reduced monetary cost
