Implementation of a Back-off Algorithm for CSMA/CD

WebExpert Answer. Two stations A and B are attempting to transmit on a local area network using 1-persistent CSMA/CD with exponential backoff algorithm. Each has a steady queue of frames ready to send. Given that A is transmitting a frame. At the end of this transmission, A will attempt to transmit its next frame while B will attempt to transmit a ... WebIn CSMA / CD protocol, After the occurrence of collision, station waits for some random back off time and then retransmits. This waiting time for which the station waits before retransmitting the data is called as back off time. Back Off Algorithm is used for calculating the back off time.

"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. " - Csma/cd backoff algorithm
