IGMP and MLD Extensions for Mobile Hosts and Routers
This document describes IGMP and MLD protocol extensions for mobile hosts and routers. IGMP and MLD are necessary protocols for hosts to request join or leave multicast sessions. While the regular IGMP and MLD protocols support communication between mobile hosts and routers over wireless networks, this document discusses the conditions how mobile hosts and routers use IGMP and MLD in their communication more effectively. Aside from a modified protocol semantic, optional "Notification function" and "Listener Hold function" for the IGMP and MLD protocols are introduced.
