Exponential backoff algorithms can be used to avoid network collisions. In a point-to-multipoint or multiplexed network, multiple senders communicate over a single shared channel. If two senders attempt to transmit a message at the same time, or "talk over" each other, a collision occurs and the messages are damaged or lost. Each sender can then back off before attempting to retransmit the same message again.
