This thesis presents a solution for boosting network mobility in the context of vehicular communications and content distribution in fixed network. Existing solutions for vehicular communications (i.e., network mobility), relies on tunneling in order to use multiple available interfaces on a vehicle. Even with tunnels, these solutions are unable to balance the traffic over available network interfaces thus do not reach the goal to provide optimum multi-homing benefits. Moreover, some of the existing solutions for network mobility, hide the mobility from the hosts connected to the mobile router. This in result inhibits the host nodes from participating in multi-homing related decisions such as interface selection which can be helpful in performing least cost routing. In this thesis, we propose to combine network mobility protocol with MPTCP which enables the host nodes to participate in mobility and multi-homing. This novel combination significantly improves routing and tunneling packet overhead. Moreover it increases throughput, fault tolerance, round-trip time and reduces transmission delay. The second contribution of this work is providing a solution for session continuity in context of content distribution in 5G networks. In 5G network, the IP edges will be closer to the host nodes in order to improve the user experience and reduce traffic load in the core network. The fact that a host can only be connected to a single gateway (SGW/PGW) at a time, would break the ongoing sessions for real time applications like video streaming or gaming during an occurrence of mobility event requiring gateway relocation. The thesis presents the solution for session continuity with the help of multipath TCP by benefiting from the fact that the content servers are stationary.
A comprehensive reference on understanding, designing, and implementing IP Mobility This authoritative reference provides readers with a thorough understanding of IP Mobility using Mobile IPv6 and companion advanced mobility protocols including network mobility and fast handovers. It illustrates basic concepts and principles behind the IP Mobility architecture and covers the practices using detailed protocol description. Of particular importance is how mobile networking will support billions of devices without restricting applications or overburdening network infrastructures, and how it will support the movement of users from network to network without compromising security. Authors Koodli and Perkins investigate how IP mobility is used in practice and the adoption of Mobile IPv6 in CDMA cellular systems. They also cover some experimental work, including performance of VoIP handovers over WLAN, multi-access network handovers, and emerging topics such as location privacy. In five parts, Mobile Inter-networking with IPv6 covers: Features of IPv6 and IP security Mobility concepts and principles, Mobile IPv6 protocol, packet handling, and network mobility Advanced mobility protocols, including fast handovers, fast handover protocol, context transfers, and hierarchical mobility management Applying IP mobility, including Mobile IPv6 in CDMA packet data networks, enterprise mobile networking, and WLAN fast handovers Emerging topics such as multi-access and mobility, seamless IP handovers, location privacy and IP mobility, and route optimization for Mobile IPv4 using Mobile IPv6 return routability With chapter exercises and handy references, readers will have plenty of opportunities to pursue topics in further detail. This is a comprehensive reference suitable for practitioners and students with a basic understanding of TCP/IP protocols.
The dissertation proposes three adaptations in the mobility management domain. The first is joint multi-layer adaptation. In this adaptation, application, network and data link layers jointly support mobility management for heterogeneous networks. The second and third adaptations are single-layer mobility management solutions. Context-Aware Adaptive Multi-homed Mobile IP is an extension to Multi-homed Mobile IP which is proposed as a single-layer entity-executed adaptation that the (CA)2RW-Com framework supports. Adaptive Performance Metric is a single-layer system-executed adaptation proposed for Access Point selection of IEEE 802.11 networks. We have modelled and validated supporting joint multi-layer mobility management proposed in the (CA)2RW-Com framework. Further, we have enabled, implemented and evaluated the single-layer mobility management solutions we propose in a simulation environment. Moreover, the dissertation discusses the prototype implementation of the (CA)2RW-Com framework and communication specification. The dissertation also presents the operational statistics of the prototype. In summary, this research presents a cohesive and holistic approach for defining a generic context-aware cross-layer framework for wireless local area networks. Further, it proposes and validates cross-layer context-aware adaptive mobility management approaches. To date, the results of this research have been published in ten peer-reviewed publications and one journal article is currently under review.
An ideal starting point for anyone wanting to learn about next generation wireless networks Gives important insights into the design of wireless IP networks Illustrates the standards and network architectures defined by leading standards bodies (including MWIF, 3GPP and 3GPP2) Discusses protocols in four key areas: signaling, mobility, quality of service, and security The authors have a good deal of experience in this field, and have many patents pending in the area of wireless networking
What is an 'all-IP' network? What difference will IP networking make to 3G services? Third Generation (3G) mobile offers access to broadband multimedia services - and in the future most of these, even voice and video, will be IP-based. However 3G networks are not based on IP technologies, rather they are an evolution from existing 2G networks. Much work needs to be done to IP QoS and mobility protocols and architectures for them to be able to provide the functionality 3G requires. IP for 3G gives a comprehensive overview of 3G networking functionality and examines how IP protocols can be developed to provide some of the basic building blocks of a mobile system (mobility, QoS and call control) Features: * Clear explanation of how 3G works at the network level. * Review of IP protocol and architectural principles. * Extensive review, classification and analysis of IP mobility protocols - macro and micro- including IPv6. * Analysis of IP QoS protocols and proposed solutions for mobile networks. * Tutorial on SIP (Session Initiation Protocol) and how SIP can be used for multimedia session control. * Description of latest UMTS developments - including Release 5. * Discussion of 4G networks - what does 4G mean? IP for 3G will appeal to mobile telecommunications and network engineers who want to know about future developments as well as system designers and developers. Students and academics on postgraduate courses related to telecommunications, especially 3G networking or IP protocols, will find this text ideal supplementary reading, only assuming a general knowledge of GSM and general networking principles.
As the volume of global Internet traffic increases, the Internet is beginning to suffer from a broad spectrum of performance-degrading infrastructural limitations that threaten to jeopardize the continued growth of new, innovative services. In answer to this challenge, computer scientists seek to maintain the original design principles of the Internet while allowing for a more dynamic approach to the manner in which networks are designed and operated. The Handbook of Research on Redesigning the Future of Internet Architectures covers some of the hottest topics currently being debated by the Internet community at large, including Internet governance, privacy issues, service delivery automation, advanced networking schemes, and new approaches to Internet traffic-forwarding and path-computation mechanics. Targeting students, network-engineers, and technical strategists, this book seeks to provide a broad and comprehensive look at the next wave of revolutionary ideas poised to reshape the very foundation of the Internet as we know it.
Quality of Service (QoS) is a standards effort to provide consistent levels of service despite delivery problems. Providing students with an understanding of the technologies and techniques that will enable Internet QoS, this book is for courses in network management.
