Seems to me the algortithim has each node operating as a repeater
requiring acknowlegement, and each node repeats to its neighbor until it
achieves acknowlegement. So the packet propagates to each nearest
neighbor until complete.
I think that with the number of hops value in the packet eliminates my doubt about the message reaching more than 1 neighbour node.
Now I am concern about the case 2 nodes send at the same time a packet. Will the packets collide and be destroyed?
Thank you again, your help is appreciated !!
