Abstract - For omnidirectional wireless broadcast,
if a node has sufficient power to broadcast to another
node, it also has the ability to broadcast to all closer
nodes. This is the wireless advantage. For the broad-
cast problem, one node (the source) is required to
communicate to all other nodes, by a single trans-
mission to the farthest node or using intermediate
hop nodes. For a given node constellation, there ex-
ist many wireless connection trees to do this. For
