Abstract
A method for routing a multicast message comprising the steps of receiving a multicast message including at least a message, a source identifier, a sequence number, a time-to-live value and a multicast group destination, determining if the multicast group destination is in a multicast forwarding table, determining if the message has been previously received, adding the multicast message to the multicast forwarding table if it is determined that the multicast message has not been previously received, determining if a node that received the multicast message is a forwarding node; randomly setting a wait time for forwarding the multicast message; and forwarding the multicast message at the expiration of the wait time.
