Abstract:
1. A method for sending multicast packets from a first node to a plurality of nodes in a wireless communication system comprising; creating a neighbor list identifying a type of node for each neighboring node in the wireless communication network wherein the type is chosen from the list of home and common; sending a multicast request from the first node having a common type to a second node having a home type; receiving the multicast request at the second node having a home type so that the second node having the home type can create a multicast packet from the multicast request; sending the multicast packet by the second node having the home type to the plurality of nodes in the wireless communication system; negotiating between the first node and a third node to determine which of the first node and the third node will become a node having a home type, wherein the negotiation is performed by assigning the home type to the first node or the third node with a higher MAC address; and changing the first node having the common type to the home type when the neighbor list of the first node is not encompassed by a destination list of the multicast packet.
