Performance analysis of Mobile IPv6 support for Dual Stack hosts

Mobility management is a key issue to achieve uninterrupted Internet services in IP based network. In IPv6, the mobility management is realized by its mobile version namely the Mobile IPv6 (MIPv6). The MIPv6 is further extended to Hierarchical MIPv6 (HMIPv6) to reduce handoff latency suffered by mobile nodes and signaling load incurred due to movement if nodes within the micro mobility region defined by HMIPv6. The HMIPv6 is considered as first widely accepted layered architecture for mobility management for IPv6 network. Influenced by the benefits of HMIPv6, many researchers have suggested extension of MIPv6 into multiple layers. However, there is very little work on finding optimal levels of hierarchy in such layered architecture. The focus of this paper is to evaluate the performance of a multilayer (N-layered with N as 5) MIPv6 architecture through experimental testbed. We have observed handoff latency, signaling overhead and tunneling cost and figured out the optimal levels of hierarchy that provides the best acceptable results for all the observed parameters. Since, HMIPv6 outperforms MIPv6 in terms of handoff latency and signaling cost, so we compare our results with HMIPv6. Testbed observation depicts that three levels of hierarchy in MIPv6 architecture provides optimal performance with 27 % reduction in handoff latency and 67 % reduction in signaling overhead compared to single layer architecture like Hierarchical MIPv6 (HMIPv6) protocol.

Client-based Mobile IPv6 (MIPv6) is the most well known mobility management protocol, and the fast emerging proxy-based Mobile IPv6 (PMIPv6) offers an alternative. Some inherent problems such as route optimization in these protocols have not been really solved. Although various proposals tried to tackle the route optimization problem, none of them has achieved a real success. Furthermore, most of them are not comprehensive solutions for coexisting MIPv6/PMIPv6 mobile environment. In this paper, we proposed a novel unified route optimization scheme - Traffic Driven Pseudo Binding Update (TDPBU) to accommodate various mobility management issues. We evaluated our proposed scheme through simulations, and numerical results show that TDPBU can significantly improve the overall performance of mobility management protocols.

The population of mobile users seeking connectivity to the Internet has been growing over the years, spurred by the capabilities of handsets and the increasing rich Internet content and resources. Mobility management to enable efficient Internet access for users on the move is thus gaining significance. With future Internet design initiatives gaining momentum, it is important that these initiatives consider mobility management as an integral part of the design, keeping in mind that these initiatives also offer the potential for new and novel mobility management schemes. In this article, we introduce the concept of Virtual Mobility Domains (VMD), and describe mobility management using the VMD approach in a newly proposed tiered Internet architecture. The results from a comparative performance study of VMD with mobility management protocols such as Mobile IPv6, Hierarchical Mobile IPv6 and Proxy Mobile IPv6 using simulations show the potential for efficient mobility management under new Internet architectures.

Performance analysis of Virtual Mobility Domain scheme vs. IPv6 mobility protocols

We address mobility management for the internet protocol version 6 in mobile networks, namely mobile IPv6 (MIPv6). To correctly transfer IPv6 packets to a mobile node (MN), the MN has to update its binding to the home network while roaming away from its home network. Mobile IP networks suffer high binding update traffic from high rates of handoffs and long packet delivery delay from the large distance to the home network. In this paper, we introduce a dynamic and distributed domain-based mobility management protocol for MIPv6 to reduce the binding update and packet delivery delay and traffic. We describe the basic protocol operations and examine the performance improvement of our mobility management over the previous mobile IP mobility management method by using simulations. We show that the dynamic approach provides the optimal mobility solution for MIPv6 and the distributed approach can decentralize the network load.

The 3G mobile network IMT-2000, was launched some years ago and multimedia traffic in the mobile Internet has been increasing with the growth of wireless access links. Next-generation networks need to efficiently transport huge volumes of multimedia traffic with high-quality mobility management. We have proposed an IP-based IMT network platform (IP/sup 2/) for the next-generation mobile network architecture and have studied its mobility management scheme, IP/sup 2/ mobility management protocol (IP/sup 2/MM). IP/sup 2/MM is a network-controlled mobility protocol that deploys mobility functions inside the network and conceals IP mobility from the mobile node. It is also designed to satisfy the requirements of mobile operators. In this paper, we introduce an overview of IP/sup 2/MM and show the comparative evaluation results with mobile IPv6. For the evaluation, we implemented both in our experimental system and compared their performance. The results show that IP/sup 2/MM provides better mobility performance than mobile IPv6, and we conclude that IP/sup 2/MM is an effective and feasible mobility protocol for the next-generation networks of mobile operators.

In this paper, we propose an IP-based mobility management protocol named Fast handover Proxy Mobile IPv6 for Sensor networks (FPMIPv6-S). FPMIPv6-S provides network-based mobility support for 6LoWPAN WSN when a sensor node moves between two Personal Area Networks (PANs). It is an improved version of the Proxy Mobile IPv6 (PMIPv6) protocol proposed for mobility management in IPv6 networks. We compared via simulations FPMIPv6-S with other well-known mobility protocol namely Mobile IPv6. Performance results show that our proposed protocol achieves reduction of packet loss by as much 70% and improve the network throughput by over 25% compared to MIPv6. Further, we implemented our proposed protocol and MIPv6 with NS3 simulator and made extensive simulations runs to compare both protocols.

This paper presents the Virtual Mobility Domain concept built to provide mobility management in a newly proposed tiered internetworking model. The proposed mobility management scheme is distinct from others by not using IP addressing, the classic IP routing protocols and providing collaborative mobility management mechanism. We investigate the handoff performance of the proposed scheme when it is deployed in varying tiers of an Autonomous System. The comparative OPNET simulation study shows that, in most cases, the proposed scheme manages a handoff in 99%, 98% and 38% less time and with 80%, 32% and 25% less signaling overhead as compared to Mobile IPv6, Hierarchical Mobile IPv6, and Proxy Mobile IPv6, respectively (see Table II).

This brief presents the challenges and solutions for VANETs security and privacy problems occurring in mobility management protocols including Mobile IPv6 (MIPv6), Proxy MIPv6 (PMIPv6), and Network Mobility (NEMO). The authors give an overview of the concept of the vehicular IP-address configurations as the prerequisite step to achieve mobility management for VANETs, and review the current security and privacy schemes applied in the three mobility management protocols. Throughout the brief, the authors propose new schemes and protocols to increase the security of IP addresses within VANETs including an anonymous and location privacy-preserving scheme for the MIPv6 protocol, a mutual authentication scheme that thwarts authentication attacks, and a fake point-cluster based scheme to prevent attackers from localizing users inside NEMO-based VANET hotspots. The brief concludes with future research directions. Professionals and researchers will find the analysis and new privacy schemes outlined in this brief a valuable addition to the literature on VANET management.

This paper proposes a low-cost global mobility management architecture and protocol procedure called LC-GM2, which is based on Proxy Mobile IPv6 (PMIPv6) networks. The benefit is the elimination of the wireless link data delivery tunnel overhead between a mobile node and the access router. To compare with the well-known Hierarchical Mobile IPv6 (HMIPv6) mobility management protocol and Global Mobility Management Architecture and Protocol Procedure (GPMIP), the location update, packet delivery, and total cost functions generated by a mobile node during its average domain residence time are formulated for each protocol based on Fluid-flow mobility model. Then, the impacts of various system parameters on the cost functions are analyzed. The analytical results show that the proposed global mobility management protocol can guarantee the lowest total costs.

The ever growing number of Internet subscribers through mobile devices has led to the requirement of better mobility management protocols. Mobile IP version 6 (MIPv6) by IETF supports IPv6 mobility by providing mobile nodes with uninterrupted Internet connectivity and services. MIPv6 provides network layer mobility but handoff from one network to another network causes handoff latency. Due to this latency some packets may be lost or delayed in transfer affecting the performance of transport layer. In this paper, we present a low-latency handoff scheme for MIPv6. The scheme requires access point to facilitate movement detection and access router to implement tentative addresses pool and neighbor cache table for faster address configuration with faster duplicate address detection. The performance analysis shows that proposed scheme provides with lower latency and packet loss as well as improved signaling cost and packet delivery cost.

차세대 무선 네트워크에서 MN의 글로벌 로밍을 효율적으로 지원하기 위해서는 원활한 핸드오버와 MN의 이동성관리는 매우 중요하다. IETF가 모바일 IPv6와 보다 확장된 IP 계층에서의 이동성관리를 제안하였지만 트래픽 특성 및 사용자의 MN에 따라 크게 좌우된다. 그러므로 이러한 요인에 관해 심도있는 성능을 평가하는 것이 중요하다. 일반적으로 IPv6 기반 이동성관리 프로토콜의 성능은 시뮬레이션을 통해 평가하는데 본 논문에서는 IPv6 기반 이동성관리 프로토콜의 성능을 평가하는 분석 프레임워크를 제안한다. 서브넷 체류 시간, 패킷 도착률과 무선연결 지연 등 시스템 매개변수들의 수학적 분석을 이용하여 핸드오프 지연, 패킷 손실에 대한 성능평가를 수행하고, 분석 결과를 통해 네트워크 매개변수와 성능분석 수치간의 상관관계를 제시한다. Mobility management of the mobile nodes and provision of seamless handover is crucial to an efficient support for the global roaming of the mobile nodes in next-generation wireless networks. Mobile IPv6 and mobility management in extended IP layer, which highly depend on traffic characteristics and user mobility models, were proposed by the IETF. Therefore, to evaluate the in-depth performance about these factors is important. Generally, the performance of IPv6-based mobility management protocol is evaluated through simulation. This paper shows the correlation between network parameters and performance metrics through numerical results, which is investigated how influence handoff latency and packet loss. And this paper uses mathematical analysis of the system parameters, such as the subnet residence time, the packet arrival rate and delay in wireless connection through the analytical framework which evaluate the performance of IPv6-based mobility management protocol.

The evolution of both Internet and cellular networks tends toward an IP mobility scheme for data and voice communication. Mobile IPv6 is specifically designed to manage host mobility between IPv6 networks. But new handheld computers or digital assistants usually integrate several network interfaces for which Mobile IPv6 is not optimized. We propose to add a strong interaction between the Link Layer and the Network Layer to anticipate Network Layer operations such as vertical and horizontal handovers.

Two of the major challenges for next-generation mobile systems are to achieve seamless mobility management in next generation wireless networks and to manage resources efficiently given the exponential growth that mobile data traffic has experienced over the last few years. To track host mobility, the IETF has made important efforts to develop mobility management protocols such as Mobile IPv6 and Proxy Mobile IPv6. These protocols establish a tunnel to connect the mobile node with its correspondent node. The tunneling method provided by MPLS can be profitably used to take advantage of MPLS traffic engineering capabilities in order to achieve faster re-routing when a mobile node changes its point of attachment to the network. Moreover, in order to deal with increasing mobile traffic demand, mobility management network architectures are being redesigned towards a more distributed operation. Given these scenarios, service disruption during handoffs continues to cause excessive packet loss that needs minimizing in order to support quality of service requirements for emerging applications. In this paper, a qualitative and quantitative analyses of the most representative host-based and network-based mobility management approaches is presented, including recent distributed mobility management approaches.

One of the research challenges for next generation all-IP-based wireless systems is the design of intelligent mobility management techniques that take advantage of IP-based technologies to achieve global seamless roaming among various access technologies. Since Mobile IPv6 is considered a mature protocol, mobility management at the network layer is the frequent approach for heterogeneous networks. The tendency of future convergent scalable architectures is splitting the mobility management in two domains, global mobility and localized mobility management. This chapter presents the advantages of MIPv6, a global mobility protocol, and its enhancements. A case study based on MIPv6 for UMTS and WiFi convergence is also presented. Proxy MIPv6, the newest protocol of the MIPv6 family, already included in the roadmap of future 4G networks, will be analyzed as a solution for localized mobility management. The main goal of the chapter is describing the way mobility protocols (MIPv6 and PMIPv6) will be implemented for the 3rd Generation Partnership Project (3GPP) Long Term Evolution architecture. The chapter ends with the presentation of the interoperation between different network technologies using global and localized mobility management protocols, which provide flexibility, scalability and independence between mobility domains.
