During operation, nodes that receive beacons from a different network will
synchronize to the different network when a predetermined condition is
met. Synchronization to the differing network will only take place if the
node receiving the beacon from a different network does not have access
to a fixed network coordinator and the predetermined condition is met.
The predetermined condition may comprise such things as a Network ID for
the different network being larger than the Network ID for the current
network, or alternatively, the size of the different network being larger
than a size of the current network.
