Inter-domain Proxy Mobile IPv6 based Vehicular Network

Procedia - Social and Behavioral Sciences, 2014

Mobile IPv6 was proposed to provide mobility support to IPv6 based mobile devices. It includes a route optimization procedure, to overcome the problem of triangular routing, which allows the correspondent node to send packets directly to the mobile node's care-of address. However, when both communicating devices are mobile, Mobile IPv6's route optimization can not handle the handover thus service disruption occurs and communication is stopped. This paper presents a new DNS-assisted solution for Mobile IPv6 to overcome the problem of simultaneous mobility. The proposed mechanism makes some necessary changes in the Mobile IPv6's route optimization procedure and executes handover differently in different scenarios depending upon the type of mobility of communicating nodes in overlapped or non-overlapped coverage access networks. Simulation results show that when proposed mechanism was used for simultaneous mobility, it successfully resumed the communication as compared to Mobile IPv6 where communication was stopped.

In Proxy Mobile IPv6 (PMIPv6), when a Mobile Node (MN) enters a PMIPv6 domain and attaches to an access link, the router on the access link detects attachment of the MN by the link-layer access. All elements of PMIPv6 including the router then provide network-based mobility management service for the MN. If the MN moves to another router in this PMIPv6 domain, the new router emulates attachment to the previous router by providing same network prefix to the MN. In other words, PMIPv6 provides rapid mobility management based on layer-2 attachment and transparent mobility support to the MN by emulating layer-3 attachment with respect to intra-domain roaming. However, when the MN moves to other PMIPv6 domains, although the domains also provide the networkbased mobility management service, the MN should exploit the host-based mobility management protocol, i.e. Mobile IPv6 (MIPv6), for the interdomain roaming. Hence, this letter proposes the rapid and transparent interdomain roaming mechanism controlled by the networks adopting PMIPv6.

Proxy Mobile IPv6 (PMIPv6) is a protocol for building a common and access technology independent of mobile core networks, accommodating various access technologies such as WiMAX, 3GPP, 3GPP2 and WLAN based access architectures. Transient Binding is a mechanism applicable to the mobile node's inter-MAG handover while using a single interface or different interfaces. Proxy Mobile IPv6 (or PMIPv6, or PMIP) is a network-based mobility management protocol This paper proposes an improvement of Proxy Mobile Ipv6 in the aspect of reducing packet loss and hand over latency. Proxy Mobile IPv6 also implements additional features not present in IPv4. This paper proposes an improvement in the Proxy Mobile IPv6.The extension of Proxy Mobile IPv6 with transient binding will support multihoming and optimizes the handover. Here the handover problem in multihoming is reduced by transient binding by using modified Local Mobility Anchor (m-LMA) with its updated Binding Cache Entry (u-BCE). Also this mechanism efficiently supports the uplink and downlink packets between mobile nodes, so it avoids superfluous packet forwarding delay and packet loss.

Recent trends show that there are swift developments and fast convergence of wireless and mobile communication networks with internet services to provide the quality of ubiquitous access to network users. Most of the wireless networks and mobile cellular networks are moving to be all IP based. These networks are connected through the private IP core networks using the TCP/IP protocol or through the Internet. As such, there is room to improve the mobility support through the Internet and support ubiquitous network access by providing seamless handover. This is especially true with the invention of portable mobile and laptop devices that can be connected almost everywhere at any time. However, the recent explosion on the usage of mobile and laptop devices has also generated several issues in terms of performance and quality of service. Nowadays, mobile users demand high quality performance, best quality of services and seamless connections that support real-time application such as audio and video streaming. The goal of this paper is to study the impact and evaluate the mobility management protocols under micro mobility domain on link layer and network layer handover performance. Therefore, this paper proposes an integration solution of network-based mobility management framework, based on Proxy Mobile IPv6, to alleviate handover latency, packet loss and increase throughput and the performance of video transmission when mobile host moves to new network during handover on high speed mobility. Simulations are conducted to analyze the relationship between the network performances with the moving speed of mobile host over mobility protocols. Based on simulation results, we presented and analyzed the results of mobility protocols under intra-domain traffics in micro mobility domain.

The Mobile IPv6 (MIPv6) mechanism requires some handover algorithm when it changes its point of attachment to the Internet. This causes MIPv6 to incur long delays and signaling loads to the backbone networks. These limitations are the result of the lack of hierarchy in the MIPv6 mobility management; using the same mechanism for macro-mobility and micro-mobility, is an inefficient use of resources in the case of local mobility. Hierarchical Mobile IPv6 (HMIPv6) is an extension of MIPv6 designed to reduce the signaling load and to improve the handover speed for mobile connections by introducing a new protocol agent called mobility anchor point (MAP) and splitting the mobility management into macro-mobility and micro-mobility schemes. However HMIPv6 only improves the micro-mobility problem while significant delay still occur in the HMIPv6 macro-mobility management because the handover algorithm is similar with the MIPv6 in this environment. This paper proposes a new fast handover algorithm that overcomes the limitations in Mobile MIPv6 and its extension HMIPv6. Our design objective is to re-establish the communication traffic flow quickly and to minimize the service disruption delay that occurs during the handover process in a macro-mobility environment. This fast handover algorithm is based on modifying the HMIPv6 protocol using the multicast technique concept. This algorithm will enable the mobile node to receive packets faster than through the HMIPv6 protocol during handover in a seamless and transparent matter.

This paper presents a handover delay analysis of networkbased handovers with Proxy Mobile IPv6 and compares its performance to Mobile IPv6. Recommendations are given to avoid excessive handover delays due to timer and configuration mechanisms in the IPv6 specification. Furthermore, extensions are proposed to make Proxy Mobile IPv6 applicable to makebefore-break handovers in multi-interface scenarios. Finally, by leveraging functions of a Multi-Radio Resource Management, handover execution can be adapted to the actual radio conditions on the terminal.

Current IP-level mobility protocols have difficulties meeting the stringent handover delay requirements of future wireless networks. At the same time they do not give sufficient control to the network to control the handover process. This paper presents an extension to Proxy Mobile IP, which is the favorite IP level mobility protocol for the 3GPP System Architecture Evolution / Long Term Evolution (SAE/LTE). The extension, Fast Proxy Mobile IPv6 (FPMIPv6), aims at solving or reducing the control and handover problem. An elementary analysis shows that FPMIPv6 can significantly reduce the handover latency and the loss of packets during handover, especially if handovers can be predicted a few tens of milliseconds before they occur.

To reduce cost and complexity of mobile subscriber devices, it is desirable that mobility may be handled by network systems only. PMIPv6 relies on MIPv6 signaling and the reuse of the home agent functionality through a proxy mobility management agent in the network to transparently provide mobility services to mobile subscriber devices. Handover latency resulting from standard MIPv6 procedures remains unacceptable to real time traffic and its reduction can also be beneficial to non real-time throughput-sensitive applications as well. This paper proposes an optimized PMIPv6 that relies on a rich set of informational resources to reduce handover delays; and then a more efficient intra mobile access gateway routing scheme

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.
