Analytical model of interaction between contention-based and deterministic channel access mechanisms in Wi-Fi Mesh networks

A new analytical model was developed to estimate the degree of mutual influence of the links between the stations of Wi-Fi Mesh networks which use different channel access methods specified by the IEEE 802.11s standard, namely, contention-based channel access mechanism and the deterministic channel access mechanism based on the preliminary reservation of channel resources. The model was used to compare the efficiency of different backoff counting methods proposed in the paper for providing the interaction between two channel access methods. Additionally, the model was also used to analyze the effect of different techniques for arranging the time intervals reserved by means of the deterministic channel access mechanism on the performance of stations using contention-based channel access mechanism.
