Step  1. Perform Condition and .
Step  2. A message is transmitted from a source module with the message to eight modules adjacent to the source module
through an external edge.
Step  3. The modules that received a message via diagonal or reverse-diagonal edges perform Condition .
Step  4. Repeat Step  3 until the message is transmitted to all modules in .
Step  5. The node with the message transmit the message to other nodes in the same module using the broadcasting scheme in
[8] when its all eight adjacent modules (except for the modules connected via dimensional edges) already had the message.
