Abstract

IGMP (Internet Group Management Protocol) is a proven technology that is widely used as the group management protocol for multicast. However, IGMP is not always suitable for wireless networks because of its communication costs, especially if clients are moving frequently. IGMP also has some security issues such as denial of service (DoS). Therefore, we propose a new group management protocol called Mobile Multicast Group Management Protocol (MMGP) for mobile multicast. MMGP is designed for use on wireless LANs and mobile networks, and is capable of reducing the communication costs even when clients move frequently. MMGP also considers security and can prevent multicast DoS. We show that MMGP is capable of realizing group management at lower communication costs than IGMP, and is suited as the group management protocol for mobile multicast.
