How much do we gain by introducing Route Optimization in Proxy Mobile IPv6 networks?
annals of telecommunications - annales des télécommunications, 2010Co-Authors: Tai-myoung ChungAbstract:Proxy Mobile IPv6 has been developed from the concept of network-based mobility support protocol in the Internet Engineering Task Force. The recently published specification of Proxy Mobile IPv6 only focuses on the mobility support without a mobile host’s participation in the mobility signaling. Then, Route Optimization issues are left in the basket for further works. In this paper, we explore the existing Route Optimization proposals that are analyzed and matched against a list of functional and operational angles. Then, the chosen two Route Optimization proposals are evaluated in terms of signaling cost, packet delivery cost, total cost, and service blocking probability. Through the provided analysis results, we demonstrate that Route Optimization solves the ineffective routing path problem when the mobile host communicates with its corresponding host and argue that the scalability of Proxy Mobile IPv6 architecture is also improved due to the distributed routing path. In addition, the cost model developed in this paper would be a reference model in order to facilitate decision making for further Route Optimization design.

using correspondent information for Route Optimization scheme on proxy mobile ipv6
Journal of Networks, 2010Co-Authors: Young-hyun Choi, Tai-myoung ChungAbstract:Proxy Mobile IPv6 outperforms previous mobility protocols have been standardized by the Internet Engineering Task Force. However, Proxy Mobile IPv6 still involves the triangle routing problem in where data packets for the mobile node are delivered throughout inefficient routing paths. To address the triangle routing problem, two different Route Optimization schemes proposed that exclude the inefficient routing paths by creating the shortest routing path. In this paper, we proposed Correspondent Information Route Optimization scheme solves the problem by inefficient signaling cost of Dutta’s Route Optimization. Using Correspondent Information for Correspondent binding updates process between the mobile access gateways which are caused by bi-path data communication of the mobile entities of different the mobile access gateway on the same local mobility anchor. The results of signaling cost performance evaluation show that performance of our proposed using correspondent information Route Optimization scheme is better than Liebsch’s Route Optimization scheme as 45% for mobility of the data packets sender and Dutta’s Route Optimization scheme as 20% for mobility of the data packets sender.

DRO: domain-based Route Optimization scheme for nested mobile networks
Eurasip Journal on Wireless Communications and Networking, 2011Co-Authors: Ming-chin ChuangAbstract:The network mobility (NEMO) basic support protocol is designed to support NEMO management, and to ensure communication continuity between nodes in mobile networks. However, in nested mobile networks, NEMO suffers from the pinball routing problem, which results in long packet transmission delays. To solve the problem, we propose a domain-based Route Optimization (DRO) scheme that incorporates a domain-based network architecture and ad hoc routing protocols for Route Optimization. DRO also improves the intra-domain handoff performance, reduces the convergence time during Route Optimization, and avoids the out-of-sequence packet problem. A detailed performance analysis and simulations were conducted to evaluate the scheme. The results demonstrate that DRO outperforms existing mechanisms in terms of packet transmission delay (i.e., better Route-Optimization), intra-domain handoff latency, convergence time, and packet tunneling overhead.

DRO: Domain-Based Route Optimization Scheme for Nested Mobile Networks
2009 IEEE Wireless Communications and Networking Conference, 2009Co-Authors: Ming-chin ChuangAbstract:Network mobility (NEMO) basic support protocol is designed to support network mobility management, and it ensures communication continuity for nodes in the mobile networks. However, NEMO in nested mobile networks suffers from the pinball routing problem, resulting in the long packet transmission delay. Therefore, we propose a domain-based Route Optimization (DRO) scheme that incorporates the domain-based network architecture and the operations of ad hoc routing protocols to perform the Route Optimization. Moreover, DRO improves the inter-domain and intra-domain handoff performance. Detailed performance evaluation is performed via comparisons with existing Route Optimization schemes. From the analysis results, we can see that DRO can achieve low packet transmission delay (i.e., better Route-Optimization) and low handoff latency.

CCNC - Proactive Route Optimization in SIP Mobility Support Protocol
2010 7th IEEE Consumer Communications and Networking Conference, 2010Co-Authors: Sangheon Pack, Pilkyoo JeongAbstract:In this paper, we introduce proactive Route Optimization (PRO) in session initiation protocol (SIP) mobility to reduce the session setup latency. In SIP-PRO, the mobility binding information is prefetched during the location registration step, and it is used for session establishment if it is valid. Proactive Route Optimization achieves the reduced session setup latency by eliminating traverse over multiple SIP servers.

Adaptive Route Optimization in Hierarchical Mobile IPv6 Networks
IEEE Transactions on Mobile Computing, 2007Co-Authors: Sangheon Pack, Xuemin Shen, Jon W. MarkAbstract:By introducing a mobility anchor point (MAP), Hierarchical Mobile IPv6 (HMIP6) reduces the signaling overhead and handoff latency associated with Mobile IPv6. However, if a mobile node (MN)'s session activity is high and its mobility is relatively low, HMIPv6 may degrade end-to-end data throughput due to the additional packet tunneling at the MAP. In this paper, we propose an adaptive Route Optimization (ARO) scheme to improve the throughput performance in HMIPv6 networks. Depending on the measured session-to-mobility ratio (SMR), ARO chooses one of the two different Route Optimization algorithms adaptively. Specifically, an MN informs a correspondent node (CN) of its on-link care-of address (LCoA) if the CN's SMR is greater than a predefined threshold. If the SMR is equal to or lower than the threshold, the CN is informed with the MN's regional CoA (RCoA). We analyze the performance of ARO in terms of balancing the signaling overhead reduction and the data throughput improvement. We also derive the optimal SMR threshold explicitly to achieve such a balance. Analytical and simulation results demonstrate that ARO is a viable scheme for deployment in HMIPv6 networks.

Adaptive local Route Optimization in hierarchical mobile IPv6 networks
IEEE Wireless Communications and Networking Conference 2005, 2005Co-Authors: Sangheon Pack, Taekyoung Kwon, Yanghee ChoiAbstract:Although hierarchical mobile IPv6 (HMIPv6) can reduce the signaling overhead and the handoff latency, it results in the non-optimal local routing problem when two mobile nodes communicate in the same mobility anchor point domain. To address this problem, we propose an adaptive local Route Optimization (ALRO) scheme. The ALRO scheme chooses either the global Route Optimization scheme or the local Route Optimization scheme depending on the session-to-mobility ratio (SMR). Based on the proposed analytical model, we find the optimal SMR threshold at which the ALRO scheme shows the best performance. Numerical results demonstrate that the ALRO scheme shows a good performance in terms of the total cost, session delivery time, and session disruption time.

VTC Fall - Proactive Route Optimization for Fast Mobile IPv6
2009 IEEE 70th Vehicular Technology Conference Fall, 2009Co-Authors: Jorge Espi, Robert Atkinson, Ivan Andonovic, John DunlopAbstract:The Fast Handovers for Mobile IPv6 (FMIPv6) protocol was developed from the experience of MIPv6 and the facilities provided by link layer triggers, allowing for a proactive approach to handover that minimises packet exchange delay and packet loss. After handover, the mobile node may carry out Return Routability with the correspondent node(s) for Route Optimization. However, this method leaves scope to optimize handover delays derived from the signalling message exchange. This paper proposes an enhancement to FMIPv6, the Proactive Route Optimization for FMIPv6 (PRO-FMIPv6) protocol, which significantly reduces the signalling and thereby improves the overall performance of the handover process. Simulation results suggest a delay reduction up to 50% over other current proposals: the FMIPv6 protocol, Enhanced Route Optimization and Proactive Bindings for FMIPv6.
