Abstract: The key functionality of backoff mechanism in wireless Ad Hoc networks was introduced and the flaws of the binary exponential backoff algorithm used in IEEE 802.11 standard were discussed. Then, various typical backoff algorithms currently proposed were reviewed in categories, their features as well as some related issues were discussed. Finally, the possible research trends on backoff algorithms for Ad Hoc networks were investigated.

Key words: backoff algorithm, wireless Ad Hoc networks, medium access control, 802.11DCF, contention window
