Detailed explanation-1: -If a collision occurs, the transmitting device waits for a small, random amount of time before retransmitting. This function is known as the. It has also been referred to as a back off timer or exponential back off.
Detailed explanation-2: -The exponential backoff algorithm is a collision resolution mechanism that uses multiplicative factors to vary the timing of repeated transmissions to avoid network collisions. Exponential backoff algorithms were initially proposed for computer networking where multiple computers share a single medium or channel.
Detailed explanation-3: -Exponential backoff is utilised during retransmission of frames in carrier-sense multiple access with collision avoidance (CSMA/CA) and carrier-sense multiple access with collision detection (CSMA/CD) networks, where this algorithm is part of the channel access method used to send data on these networks.
