Abstract
A method and apparatus is disclosed herein for performing multi casting. In one embodiment, the method comprises receiving routing, association, relaying, and/or topology information associated with a plurality of nodes in a multi-hop wireless network, the plurality of nodes communicably coupled in a tree or mesh arrangement via a plurality of broadcast channels; and determining a subset of the plurality of nodes over each broadcast channel on the multi-hop wireless network that is responsible for sending acknowledgment information, in response to receipt or lack of receipt of transmissions, back to senders of transmissions.
