15. A method comprising:
setting a transmission threshold to a first value;
measuring a first signal strength magnitude of the communication channel;
comparing the first signal strength magnitude to the transmission threshold;
on a condition that the first signal strength magnitude is less than the transmission threshold, transmitting a message on the communication channel; and
on a condition that the first signal strength magnitude is not less than the transmission threshold, increasing the transmission threshold by an increment from the first value to a second value to which a second signal strength magnitude of the communication channel will be compared to determine whether to transmit the message on the communication channel;
determining that the signal strength magnitude of the communication channel has been measured at least a threshold amount of times; and
transmitting the message via the communication circuit on the communication channel based on the determination that the signal strength magnitude has been measured at least the threshold amount of times.
