We model cooperating repeater stations serving the radio amateur operators of the nations largest cities. Messages originate over one evening of operation where random members of the population send to other members with no immediate reply or notification of delivery.
The stations themselves would be responsible for storing and forwarding messages based on only partial information about the whole of the evolving network.
We chose to assemble stations into regions and those into zones such that traffic destine to another region or zone could be forwarded in the right general direction.
See Next Hop Routing
We model one-way send-and-forget messages will arrive to be forwarded over a period of activity and at some system independent average rate.
See Message Traffic
Transmissions from neighbors can interfere with signals. We model delay from retries on a busy channel.
