This paper presents comparative results on Hierarchical Mobile IPv6 and Proxy Mobile IPv6. The two mobility support protocols
have similar hierarchical mobility management architectures but there are, however, clearly different perceptions: Hierarchical
Mobile IPv6 has specific properties of a host-based mobility support protocol, whereas Proxy Mobile IPv6 is based on a network-based
mobility support protocol. Thus, it is important to reveal their mobility characteristics and performance impact factors.
In this paper, a cost based evaluation model is developed that evaluates the location update cost, the packet delivery cost,
and the wireless power consumption cost based on the protocol operations used. Then, the numerical results are presented in
where impacts of the various system parameters are evaluated. The results demonstrate that Proxy Mobile IPv6 always outperforms
Hierarchical Mobile IPv6 due to its ability to avoid the mobility signaling sent by the mobile host, and its reduced tunneling
overhead during communications with other nodes. 相似文献

Recently, the world has become increasingly mobile, and people have started communicating by wireless networking. Mobile IPv6 enables mobile users to communicate with each other while moving. In this study, a mobile IPv6 network was implemented by the IEEE 802.11 specification, and its performance was analyzed using TCP and UDP applications. The experimental results indicate that throughput stabilized for UDP applications after about 6–14 seconds. However, TCP applications were found to stabilize throughput in 10–20 seconds. The evaluation results reveal that TCP applications perform less well in mobile IPv6 networking than UDP applications. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

Handover delay performance is a critical issue to support real-time applications in wireless networks. To address this issue, this paper presents an Enhanced fast handover Triggering Mechanism (ETM) to improve the handover performance of mobile nodes (MNs) in Fast Proxy Mobile IPv6 (FPMIPv6). Making use of the information from the link layer, the ETM predicts two cases that the MNs perform in the reactive handover mode. Then, it establishes the bi-directional tunnel in advance for fast handover. As a result, the reactive handover delay is significantly reduced. Integrating the ETM into FPMIPv6 forms an enhanced Fast Proxy Mobile IPv6 (eFPMIPv6) protocol. Simulation experiments show that with the presented ETM mechanism, the eFPMIPv6 outperforms the original FPMIPv6 in terms of the overall handover performance. 相似文献

This paper specifies a global mobility management architecture and protocol procedure called GPMIP, which is based on Proxy Mobile IPv6. In GPMIP, mobility management is performed by the network entity rather than individual mobile nodes. 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 mobility management protocol, 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 indicate that the proposed global mobility management protocol can guarantee lower total costs. Furthermore, a qualitative comparison between GPMIP and some other global management protocols is also investigated. 相似文献

Proxy Mobile IPv6 (PMIPv6) is designed to provide a network-based localized mobility management protocol, but it does not handle the global mobility of hosts. In this paper, we propose a location management scheme based on Domain Name System (DNS) for PMIPv6 which can support global mobility by using DNS as a location manager. In addition, to support large numbers of mobile terminals and enhance network scalability a paging extension scheme is introduced to PMIPv6.To evaluate the proposed location management scheme, we establish an analytical model, formulate the location update cost and the paging cost,and analyze the influence of the different factors on the total signaling cost. The performance results show that our proposed scheme outperforms the basic PMIPv6 under various parameters in terms of reducing the signaling overhead and the proposed scheme reduces signaling overhead compared to the basic PMIPv6. 相似文献

Route optimization (RO) developed for Proxy Mobile IPv6 (PMIPv6) aims at reducing the packet transmission cost. However, as
we present in this paper, the RO procedure may cause out-of-order packets. In this paper, we propose a tunnel restraint scheme
to minimize out-of-order packets during a mobile node (MN)’s handover by utilizing a developed estimation function that calculates
an amount of out-of-order packets in the RO procedure. In the proposed tunnel restraint scheme, buffering techniques at proxy
mobility agents are adopted to minimize the arrival of out-of-order packets to the MN. The proxy mobility agents taking part
in the RO procedure buffer the packets for the MN until they establish the RO tunnel between them. The conducted performance
evaluation results show that the traffic rate and the time period of out-of-order packets mainly have effects on the out-of-order
packets problem. We also demonstrate that the proposed tunnel restraint scheme enhances the performance of PMIPv6 RO by minimizing
the number of out-of-order packets. 相似文献

Proxy Mobile IPv6 (PMIPv6) is a networked-based handover protocol for the IP layer, i.e., the layer 3 mobility management protocol. In this work, we integrate fast handover and IEEE 802.21 Media Independent Handover (MIH) Services with PMIPv6 to improve the handover performance over the heterogeneous wireless network environment. Since it may have multiple candidate destination networks to which a Mobile Node can select for handover, it needs to consider not only the signal strength but also the corresponding networking situation for the proper selection of the next network. To reduce the packet loss situation, the multicast mechanism is adopted to forward packets to these candidate destination networks during the handover processing period. In this work, a Forward Fast Media Independent Handover Control Scheme for Proxy Mobile IPv6 (FFMIH-PMIPv6) is proposed based on the aforementioned concerns. Through the simulations for performance analysis, it shows that the proposed FFMIH-PMIPv6 can have better handover performance in terms of handover latency, packet loss rate and throughput. 相似文献

The LTE (Long Term Evolution) technologies defined by 3GPP is the last step toward the 4th generation (4G) of radio technologies designed to increase the capacity and speed of mobile telephone networks. Mobility management for supporting seamless handover is the key issue for the next generation wireless communication networks. The evolved packet core (EPC) standard adopts the proxy mobile IPv6 protocol (PMIPv6) to provide the mobility mechanisms. However, the PMIPv6 still suffers the high handoff delay and the large packet lost. Our protocol provides a new secure handover protocol to reduce handoff delay and packet lost with the assistance of relay nodes over LTE networks. In this paper, we consider the security issue when selecting relay nodes during the handoff procedure. During the relay node discovery, we extend the access network discovery and selection function (ANDSF) in 3GPP specifications to help mobile station or UE to obtain the information of relay nodes. With the aid of the relay nodes, the mobile station or UE performs the pre-handover procedure, including the security operation and the proxy binding update to significantly reduce the handover latency and packet loss. The simulation results illustrate that our proposed protocol actually achieves the performance improvements in the handoff delay time and the packet loss rate. 相似文献

Mobile IPv6 provides global mobility and location management support for the IPv6 network layer protocol. The design of Mobile IPv6 incorporates security features that differ significantly from its predecessor, Mobile IPv4. Some of the new security features are intended to counter new threats raised by route optimization, while others align Mobile IPv6 security more closely with basic IPv6 security mechanisms. In this paper, we outline the security threats to Mobile IPv6 and describe how the security features of the Mobile IPv6 protocol mitigate them. 相似文献

In the Mobile IPv6 (MIPv6) protocol, a mobile node (MN) is a mobile device with a permanent home address (HoA) on its home link. The MN will acquire a care‐of address (CoA) when it roams into a foreign link. It then sends a binding update (BU) message to the home agent (HA) and the correspondent node (CN) to inform them of its current CoA so that future data packets destined for its HoA will be forwarded to the CoA. The BU message, however, is vulnerable to different types of security attacks, such as the man‐in‐the‐middle attack, the session hijacking attack, and the denial‐of‐service attack. The current security protocols in MIPv6 are not able to effectively protect the BU message against these attacks. The private‐key‐based BU (PKBU) protocol is proposed in this research to overcome the shortcomings of some existing MIPv6 protocols. PKBU incorporates a method to assert the address ownership of the MN, thus allowing the CN to validate that the MN is not a malicious node. The results obtained show that it addresses the security requirements while being able to check the address ownership of the MN. PKBU also incorporates a method to verify the reachability of the MN. 相似文献

Typical PMIPv6 supports mobility management for the Mobile Host (MH) in localized domains over variant Wireless Local Area Network technologies. The typical PMIPv6 adopted in reactive mode in which break-before-make technique may concern, which results in long disruption latency and inevitable data traffic loss that negatively affects MH’s communication performance. This article proposes a proactive latency low handover mechanism, which corresponds to make-before-break technique in order to support MH’s seamless and fast roaming in PMIPv6 network. The proposed mechanism proactively performs a pre-registration and pre-access authentication processes tightly together intended for the MH in advance of a handover situation involved in typical PMIPv6, thereby enabling the MH to re-configure its interface more quickly after a handover. Consequently, the associated mobility-related signallings along with their latencies are reduced significantly and the continuity of the MH communication session is granted. Furthermore, an efficient buffering technique with optimized functions is introduced at the MH’s anchor mobility entity to prevent data traffic loss and save their transmission cost. Through various simulation evaluations via ns-2, we study and analyse different mobility aspects, such as handover latency, data traffic loss, throughput, end-to-end traffic delay, traffic transmission cost and signalling cost, with respect to different traffic sources like CBR-UDP and FTP-TCP. Several experiments were conducted, revealing numerous results that verify the proposed mechanisms’ superior performance over existing scheme. 相似文献
