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. dhss subventionWebOct 5, 1994 · The proposed algorithm, which we call the capture avoidance binary exponential backoff (CABEB), uses the standard binary exponential backoff (BEB) with enhancements for collision resolution in the special case when a station attempts to capture the channel subsequent to an uninterrupted consecutive transmit. dhss state holidaysWebsion terminates.
