Proxy Mobile IPv6 Based Multicast Listener Mobility Architecture

Proxy mobile IPv6 (PMIPv6) is being actively standardized by IETF, and its salient features, such as supporting unmodified mobile node (MN), expedite the real deployment of IP mobility management. However, current research and development mainly focus on its unicast mechanism. In this paper, we propose two multicast listener mobility mechanisms for PMIPv6, named LMA-MLM and MAG-MLM, by drawing a lesson from the designing of Mobile IP (MIP) based multicast solutions. Moreover, we present qualitative and quantitative comparison between MlP-based solutions and our proposals. Although the research of PMIPv6-based multicast mobility is at an early stage yet, it is strongly expected to be a promising candidate solution for multicast mobility in the wireless mobile IP networks.
