Multicast Extension to Proxy Mobile IPv6 for Mobile Multicast Services

Abstract

Recently, Proxy Mobile IPv6 (PMIPv6) has received much attention as a mobility management protocol in next-generation all-IP mobile networks. While the current research related to PMIPv6 mainly focuses on providing efficient handovers for unicast-based applications, there has been relatively little interest in supporting multicast services with PMIPv6. To provide support for multicast services with PMIPv6, there are two alternative approaches called Mobile Access Gateway (MAG)-based subscription and Local Mobility Anchor (LMA)-based subscription. However, MAG-based subscription causes a large overhead for multicast joining and LMAbased subscription provides non-optimal multicast routing paths. The two approaches may also cause a high packet loss rate. In this paper, we propose an efficient PMIPv6-based multicast protocol that aims to provide an optimal delivery path for multicast data and to reduce handover delay and packet loss rate. Through simulation studies, we found that the proposed protocol outperforms existing multicast solutions for PMIPv6 in terms of end-to-end delay, service disruption period, and the number of lost packets during handovers.

Evaluation of an Enhanced Multicast Data Flow Technique in Network Mobility

“…The implementation of the MFR and RC operations is at the LMAs and MAGs. Figure 2 and Figure 3 shows the handover signaling flow for the MPMIPv6 [7,8] and the MPMIPv6 with RC respectively. The signaling flow of the proposed scheme MPMIPv6 RCMFR is shown in Figure 4.…”

“…However in case of MPMIPv6 with RC, the handover latency, γ h -RCMPMIPv6 β h -RCMPMIPv6 = I ls + 2I pMAGnMAG + 3I nMAGLMA (8) As for the proposed enhancement MPMIPv6 with RCMFR, the handover latency, γ h -…”

“…As a solution to this issues and the huge increase in mobile multicast IP traffic, this research proposed an enhancement to support high data delivery performance in Mobile IPv6 (MIPv6) [6]. The enhanced technique is based on multicast method with Proxy Mobile Ipv6 (PMIPv6) [7][8]. In the proposed technique the multicast traffic is processed and…”

Packet Loss and Packet Delivery Evaluation Using Network Simulator for Multicast Enabled Network Mobility Management

“…This paper presents an improvement in term of packet loss and packet delivery in order to provide high context delivery in multicast enabled network mobility management. The improvement is done via implementation of Proxy Mobile Ipv6 (PMIPv6) [7][8] with context delivery [9][10][11] and multicast fast rerouting [12]. This new implementation is called CTMFR.…”

Handover Analysis for Multicast Enabled Network Mobility Management Using Network Simulator

“…The improved method is an integration of two methods. These methods are implemented in network mobility management called Proxy Mobile IPv6 (PMIPv6) [7][8]. The two methods are Context Transfer [9][10][11] and Multicast Fast Reroute [12].…”
