Abstract
In order to improve the performance of IEEE 802.11 DCF,based on the existing protocol S-DCF,through the improvement of optimal transmission probability of τ,a new approach based on minimum contention window-based channed access mechanism was proposed.The algorithm can optimize performance of wireless network through the dynamic adjustment of the contention Window double and reset the probability according to network size.The mathematical modeling and theoretical analysis were carried out using Markov chain PPT-DCF.The results showed that when the network size varies,PPT-DCF performance has more better than the S-DCF does.
