Study of Fairness and delay of packet scheduling In IEEE 802.11 based Wireless Mesh Network

Now-a-days Wireless Mesh Network (WMN) has come up as a widely used technology because of its robustness and cost effectiveness. But it also has some challenges which need to be addressed. Fair packet scheduling is one of the challenging issues as it affects the quality of service (QoS) offered by the WMN to its users. For measurement of fairness, delay is an appealing parameter as the delay suffered by the users of the WMN should be fair enough to get a fair treatment from the network. In this paper, a new fairness index has been computed considering total delay experienced by the packets. For calculating total delay both queuing delay and MAC delay have been considered. Finally, a comparative study have been carried out among different standards of IEEE 802.11s to study the fairness that they offer.
