MULTICAST-SUPPORTED FAST HANDOVER FOR Proxy Mobile IPv6

Abstract

Proxy Mobile IPv6 is a network-based mobility management protocol which is attractive as it does not require the participation of mobile nodes in mobility-related signaling. Unlike the host based approaches like Mobile IPv6, in PMIPv6 the Mobility Access Gateway (MAG) is responsible for tracking the movements of Mobile Node (MN) and to initiate the handover process. In this study, a novel method of multicasting the data packets to both the previous and the new MAGs by Local Mobility Anchor (LMA) during the handover process is proposed. The experimental results show that the handover delay is greatly reduced when compared to the existing approaches and the packet loss during the handover process is reduced.
