Mobile IPv6 (MIPv6) has been standardized for mobility management in the IPv6 network. When a mobile node changes its point of attachment in the IPv6 network, it experiences a time due MIPv6 procedures when it cannot receive or send any packets. This time called the handover delay might also cause packet loss resulting undesired quality-of-service degradation for various types of applications. The minimization of this delay is especially important for real-time applications. In this chapter we present a fast handover method called the flow-based fast handover for Mobile IPv6 (FFHMIPv6) to speed up the MIPv6 handover processes. FFHMIPv6 employs flow information and IPv6-in-IPv6 tunneling for the fast redirection of the flows during the MIPv6 handover. Also, FFHMIPv6 employs a temporary hand-off-address to minimize the upstream connectivity. We present the performance results comparing the FFHMIPv6 method to other fundamental handover methods with Network Simulator 2 (ns-2) and Mobile IPv6 for Linux (MIPL) network.

Signalling Overhead

Due to the proliferation of handheld mobile devices, multimedia applications like Voice over IP (VoIP), video conferencing, network music, and online gaming are gaining popularity in recent years. These applications are well known to be delay sensitive and resource demanding. The mobility of mobile devices, running these applications, across different networks causes delay and service disruption. Mobile IPv6 was proposed to provide mobility support to IPv6-based mobile nodes for continuous communication when they roam across different networks. However, the Route Optimization procedure in Mobile IPv6 involves the verification of mobile node’s reachability at the home address and at the care-of address (home test and care-of test) that results in higher handover delays and signalling overhead. This paper presents an enhanced procedure, time-based one-time password Route Optimization (TOTP-RO), for Mobile IPv6 Route Optimization that uses the concepts of shared secret Token, time based one-time password (TOTP) along with verification of the mobile node via direct communication and maintaining the status of correspondent node’s compatibility. The TOTP-RO was implemented in network simulator (NS-2) and an analytical analysis was also made. Analysis showed that TOTP-RO has lower handover delays, packet loss, and signalling overhead with an increased level of security as compared to the standard Mobile IPv6’s Return-Routability-based Route Optimization (RR-RO).

Handover Scheme

Delay and packet loss caused by the basic mobile IPv6 handover protocol can not guarantee the service quality of real-time communication. In order to improve the performance of fast handover of the mobile IPv6, we proposed a fast handover scheme based on hierarchical mobility which combines micro mobility and the link layer trigger. By shielding local mobility of the mobile node, the scheme can greatly reduce the signaling information traffic from mobile node to HA and CN. Through the link layer trigger mechanism, the scheme builds a tunnel in advance to avoid packet loss. In order to verify the performance of the proposed scheme, we did some simulation experiments in the NS-2 environment. The simulation results show that the scheme reduces handover delay and packet loss effectively.

Better Than

The main purpose of IP next generation version 6 or called IPv6 is to meet the needs of IP addresses for the long term. With the presence of IPv6 it is also necessary routing protocol that supports IPv6 network. Routing protocols work to connect between networks, and choose paths or routes to reach other networks. There are three types of routing protocols that already support IPv6 services. Among other types of distance vector (RIPng), link-state (OSPFv3) and hybrid (EIGRPv6). This final project is designed to know the performance of the three types of routing protocols on IPv6 network. Testing is done by analyzing routing update process, ICMPv6 packet analysis and testing by sending Real-time Transport Protocol (RTP) packet in the form of audio video stream sent via server and accessed through client. In the simulation and analysis results using GNS3 (Graphic Network Simulator 3) and wireshark found that the OSPFv3 performance testing is better than EIGRPv6 and RIPng when performing routing updates or when link down occurs. Then the data analysis of test results with the delivery of Real-time Transport Protocol package so that it can be concluded that OSPFv3 algorithm better than EIGRPv6 and RIPng in terms of delay, packet loss, throughput and jitter.

The Creation

IETF has specified Mobile IPv4 and Mobile IPv6 in RFC3344 and RFC3775 respectively, but not yet discussed Mobile IPv4/v6 in any published RFC. This paper proposes a scheme to solve one of Mobile IPv4/v6 problems which Home Agent (HA) locates in IPv6 network, and Correspondent Node (CN) locates in IPv4 network, while Mobile Node (MN) moves within IPv4 network. In the solution, a gateway called Mobile IPv4/v6 translation gateway (MIPv4/v6-TG) is introduced to bridge between IPv4 network and IPv6 network, which is made up of a traditional NAT-PT gateway and a Mobile IP application level gateway (MIP-ALG) built upon the NAT-PT gateway. MIP-ALG maintains a MIP table, a data structure, which is formed by entries. We use the MIP table to realize the communication between the IPv4 entities and the IPv6 entities. The creation, usage and update processes of MIP table are described in this paper. And it can work compatibly with RFC3344 and RFC3775.
