摘要：Unfairness is one of the major problems in WMN as each node operates not only as a host but also as a router, forwarding packets on behalf of other nodes that may not be within the direct wireless transmission range of their destinations and thereby adding delay and affecting the throughputs of the node. Addressing end-to-end unfairness in wireless mesh network is necessary for the network to be scalable otherwise; the expected network scalability will not be met. The unfairness investigation shows that the end-to-end unfairness in a wireless mesh network will affect the network scalability. Modification to the network layer has been proposed to include an additional queue, a weighted fair scheduler and a classifier to separate locally generated flow from the relayed flows at each node. This will make the traffic flows from all the sources in the network to achieve equal throughput at the destination irrespective of the number of hops traversed. Another unfairness issues is also investigated at the MAC layer as a result of adopting existing single hop MAC protocol to be used in this multi-hop mesh network.
