Internet Group Management Protocol Fails In A Radio LAN Environment

To those that think IP Multicast works in a radio environment there is one little problem. IGMP is not a reliable protocol.  How IGMP attempts to gain reliability is by sending several copies of its messages. For example; the IGMP join group message will be sent several times, after all, isn’t it ok as long as the intended receiver of the IGMP message is aware of this “feature”. The problem is when it comes to the radio LAN environment packet loss is often so high that those little IGMP packets are often stepped on.
