ABSTRACT:
Transmission of a first message over a local area network is delayed by a delay value. The delay value is calculated based on a backoff value in a backoff counter and a generated random number. Transmission of the first message is deferred when another node on the local area network begins transmission of another message while transmission of the first message is being delayed for the delay value. The backoff value in the backoff counter is incremented when the transmission of the first message is deferred. The backoff value in the backoff counter is incremented when transmission of the first message collides with transmission of another message by another node on the local area network. The backoff value in the backoff counter is decremented when the first message is transmitted without being deferred and without colliding with transmission of another message.
