To improve the performance of IEEE 802.11 wireless LAN, a novel contention aware adaptive contention window scheme is proposed in this paper. Compared with the binary exponential backoff algorithm defined in standard, our scheme can determine the contention window based on the collision status rapidly and the collision probability can be reduced dramatically. The analysis results show that our mechanism...
A novel contention aware adjusting mechanism is proposed in this letter. Compared with the Binary Exponential Backoff algorithm defined in standard, our scheme can determine the contention window based on the collision status rapidly and the collision probability can be reduced dramatically; moreover, the dynamical varying timing method can make the node adjust the number of packets sending to MAC...
