WebJul 5, 2024 · A Computer Science portal for geeks. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. 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.

WebThe backoff algorithm greatly affects the performance of CSMA/CA because it determines the time that the stations wait for before transmission when the medium is sensed busy. WebCSMA/CD examples • Example (Ethernet) – Transmission rate = 10 Mbps – Packet length = 1000 bits, D Tp = 10-4 sec – Cable distance = 1 -mile, τ = 5x106 sec ⇒ β = 5x10-2 and E …
