More and more access points (AP) are deployed to enable seamless coverage. Because the number of available orthogonal channels is limited, it is inevitable that many APs/nodes have to contend for a common channel. Without careful design, the increase in the number of APs only adds to co-channel interference and may even degrade the total performance. It is well known that transmit power control in the densely deployed WLAN can effectively improve spatial reuse of the channels. Coordination among APs and nodes, however, is necessary in order to avoid asymmetric link (starvation, hidden terminal) problem and ensure the fairness. In this paper, we discuss (i) how to maximize network throughput by balancing the tradeoff between transmit rate (require large power) and spatial reuse of channels (require small power), and, (ii) how to ensure the fairness. The extensive simulations under Scenargie show that the proposed scheme can effectively improve the total throughput and fairness of dense WLANs. |
