Abstract

In IEEE 802.11 wireless LAN, the bandwidth cannot be fairly allocated among stations. To resolve this problem, we propose a novel adaptive wireless bandwidth allocation for per-station fairness. The proposed scheme can fairly allocate the bandwidth to each wireless station based on the maximum capacity of the wireless link and number of wireless stations. When there is a remaining bandwidth in the network, the remaining bandwidth can be flexibly allocated to greedy stations. The experiment results on a real testbed reveal that this scheme can improve the per-station fairness. Furthermore, the proposed scheme can be implemented on wireless access router. Hence, in order to support legacy wireless clients, our solution can be efficiently used.
