with 14 neighbors, the probability of having exactly one mote transmit in a cell is lowest when each node transmits with 1/14 probability, assuming all nodes have something to send. Apply that rule to transmitting data.

The medium access is:

on any TXRX slot, pick a random number
for 1/14 of the probability, look for a packet to TX in the queue, if there transmit
in any other case, listen
