Abstract:

Traditional backoff algorithms in distributed contention-based MAC protocols adopt contention window scheme for collision resolution. Collided nodes are redistributed in extended windows to avoid further collision. However, collision may still occur due to intersecting window ranges. In this paper, we propose an effective backoff algorithm featuring collision-free collision classification resolution (CF-CCR) based on collision classification model to resolve different collisions with different manners. Under the schedule of CF-CCR, the network will ultimately converges to a collision free state, in which nodes access channel sequentially with no collision occurred. The simulation results show that CF-CCR outperforms IEEE 802.11 DCF in collision times, throughput, delay and fairness.
