Abstract

In Carrier-Sense Multiple Access with Collision Detection (CSMA/CD), exponential back off is used to determine the wait time after a collision before retransmitting. Instead of exponential back off, single exponential smoothing provides a better method to determine back off time after each collision. Exponential smoothing has the advantage of giving a higher weighting to the most recent values.
