Description: In this thesis, the performance of the original IEEE 802.11 DCF is quantitatively analyzed through Bianchi’s model. Whereafter an approache to alleviate this problem is proposed. Theoretical analysis and related simulations is performed. The results show that our proposed methods can improve DCF perofrmance in WLAN by a large margin (compared with the original standard).
In the process of analyzing the performance of the original DCF, another problem was heeded that the DCF performance reduces with increasing number of active stations in the network.The main reason of this problem is the high probability of collision, when the load of the network is high. This problem can be solved by speeding up the process of contention window incressing. A new algorithm is designed in which the active stations can adapt their backoff exponent to the channel conditions dynamically. The theoretical analysis is performed and its accuracy is valuated by related simulations.The effective througuput of t
