Joining the Multicast Tree: AODV Multicast tree links H Group member C A Tree (but not group) member E G B L Group leader K J N D N has joined the group 208

Sending Data on the Multicast Tree Data is delivered along the tree edges maintained by the Multicast AODV algorithm If a node which does not belong to the multicast group wishes to multicast a packet It sends a non-join RREQ which is treated similar in many ways to RREQ for joining the group As a result, the sender finds a route to a multicast group member Once data is delivered to this group member, the data is delivered to remaining members along multicast tree edges 209
