===== Protocol =====

==== Assumptions ====


Node **S** wants to send a message to node **D**.

==== Sending messages on known routes ====

  - **S** searches its route cache.
  - If a suitable route is found, send the message along the route, placing in the header the whole sequence of hops that the message should follow on the way to **D**.

==== Route discovery ====

  - **S** sends a ''Route Request'' message to every reachable node.
  - 

==== Route maintenance ====
