Asian Info-communications Council Working Group 1 TITLE: Multicast for Mobile Hosts in IP Networks THEME: Wireless Technologies

Abstract In today’s Internet, the need for multimedia communication leads to rapid progress in multicast technology. Using multicast can efficiently deliver packets to a group of receivers. Compared with unicast, multicast can significantly reduce the bandwidth demand in networks. In the meantime, with the wide use of mobile devices and the introduction of Mobile IP, people can contact with the Internet at anytime and anywhere. It is a very meaningful work to support multicast in Mobile IP. In this paper, we will analyse and evaluate several mobile multicast protocols and provide a new one which is based on Mobile IPv6
