This means that there can't be any loop in the routing table. The proof was done completely automatically and our algorithm was able to generate all ...

... Most routing protocols for ad-hoc wireless networks assume point-to-point communication, whereby each node forwarding the packet on its way to the destination sends it to a specific neighbor. Regardless of whether the scheme is proactive [14, 1] or reactive [13, 10, 8, 12, 16, 6], its primary object ...
