The Improved Research on IEEE 802.11 Mac Layer Access Mechanism

Abstract— The mechanism of IEEE 802.11 is random access, which exhibits a significantly increased probability of collision when there are too many access points, thereby diminishing the performance. This paper introduces a distribution mechanism to improve the current random MAC layer access mechanism involving a combination of distribution and competition with dividing one working cycle into two parts by managing the transmitting sequence. The simulation experiment indicates that the improved protocol can increase network throughput while maintaining a relatively lower end-to-end delay.
