End-system-based mobility support in IPv6

MSR Asia TR-29-2004, 2004

Despite voluminous mobility solutions that have been proposed in the past, none of them have been widely deployed today. To address the deployment difficulty in previous work, we propose an end-system based mobility management scheme in IPv6 (EMIPv6) for Internet hosts. In our design, we leverage distributed hash table-based peer-topeer systems to carry out scalable, robust and self-organizing name lookup for mobile hosts. And we adhere to the end-toend principle [1] by performing connection ...

With the growing number of mobile nodes and projections that this number will far exceed that of stationary nodes, mobility management becomes an important aspect of the next generation networks. Mobile operators are therefore looking to deploy a functional and optimized protocol that allows management of mobility while offering additional functionalities, such as simultaneous multi-access and flow mobility (important for Fixed-Mobile Convergence (FMC) for instance). Two major protocols exist that offer mobility management for Internet Protocol (IP) networks, Mobile IPv6 (MIPv6) and Proxy Mobile IPv6 (PMIPv6). However, both protocols have shortcomings that hinder their deployment on a massive scale. We therefore propose a new protocol, based on the current MIPv6 specifications, that addresses these shortcomings. It can be seen as a hybrid protocol offering simultaneously client and network mobility managements, which can be labeled "client-based network-assisted". We compare it to the existing two protocols and show that it doesn't suffer from their drawbacks.

Mobility is becoming ubiquitous now-a-days; there have been tremendous advances in the next generation mobile communication systems recently, thereby, engendering the need to support all the advancements arising from new theories, algorithms, architectures, standards and protocols. Mobility management has been a growing concern in IPv6 with numerous problems originating from roaming between IPv6 access networks and IPv4 access networks owing to ever-growing research. This paper attempts to succinctly address the enhancement(s) required for IPv6 mobility management protocols for future access networks. Further, the solutions for roaming issues between IPv6 and IPv4 networks have also been highlighted.

Mobility management is one major challenge for wireless network design. Advanced wireless technologies provide mobile nodes with multi-mode radio interfaces, so subscribers can benefit from disparate mobile communication systems. Meanwhile, researchers are putting efforts into standardization of IPv6-based mobility protocols. Hence, wireless networks can offer more flexible mobility support than ever before. However, as the demands for high-speed Internet access and multimedia services increase, guaranteeing host mobility with quality of service provisioning becomes more difficult. Both network connectivity and session continuity need to be carefully handled during handover. This paper proposes a new mobility protocol, called seamless mobile IPv6 (SMIPv6). Its novelty consists of pre-configuring bidirectional secure tunnels among access routers before handoff, as well as using such tunnels to guarantee handoff seamlessness. To evaluate the performance, simulations are conducted using OPNET Modeler v.12.0, of which results demonstrate that SMIPv6 delivers better performance than MIPv6 in terms of handoff latency and packet losses.

Video is a major challenge for the future mobile Internet as it is foreseen to account for close to 64% percent of consumer mobile traffic by 2013. However, the current Internet, and in particular the mobile Internet, was not designed with video requirements in mind and, as a consequence, its architecture is very inefficient when handling this type of traffic. This paper presents a novel mobility architecture inspired by the Distributed Mobility Management paradigm, capable of coping with the future video traffic demands, in a distributed and more scalable way. In the proposed solution, mobility support services are spread among several nodes at the edge of the network, thus realizing a flatter architecture and pushing services closer to the terminals. Our approach overcomes some of the major limitations of centralized IP mobility management solutions, by extending existing standard protocols.

The use of centralized mobility management approaches -such as Mobile IPv6 -poses some difficulties to operators of current and future networks, due to the expected large number of mobile users and their exigent demands. All this has triggered the need for distributed mobility management alternatives, that alleviate operators' concerns allowing for cheaper and more efficient network deployments. This paper proposes a distributed mobility solution, based on Mobile IPv6 and the use of Cryptographic Generated Addresses. We analytically compare the solution to Mobile IPv6, and derive in which scenarios it performs best.

The NEMO (NEtwork MObility) protocol, as normalized by IETF, allows a transparent movement of a whole IPv6 network. This mobile network can thus attach to different points in the Internet without losing TCP/IP connectivity of its mobile nodes. In this paper we briefly describe the NEMO protocol and present a simple architecture deployed to test its main functionalities. We also discuss the results obtained thus far with the use of popular TCP and UDP applications in a mobile environment: video streaming transfer, remote access using SSH and FTP file transfer.

Mobile IP is one of the dominating protocols that enable a mobile node to remain reachable while moving around in the Internet. However, it suffers from long handoff latency and route inefficiency. In this article, we present a novel distributed mobility management architecture, ADA (Asymmetric Double-Agents), which introduces double mobility agents to serve one end-to-end communication. One mobility agent is located close to the MN and the other close to the CN. ADA can achieve both low handoff latency and low transmission latency, which is crucial for improvement of user perceived QoS. It also provides an easy-to-use mechanism for MNs to manage and control each traffic session with a different policy and provide specific QoS support. We apply ADA to MIPv6 communications and present a detailed protocol design. Subsequently, we propose an analytical framework for systematic and thorough performance evaluation of mobile IP-based mobility management protocols. Equipped with this model, we analyze the handoff latency, single interaction delay and total time cost under the bidirectional tunneling mode and the route optimization mode for MIPv6, HMIPv6, CNLP, and ADA. Through both quantitative analysis and NS2-based simulations, we show that ADA significantly outperforms the existing mobility management protocols.
