Self management of rate, power and carrier-sense threshold for interference mitigation in IEEE 802.11 networks

Abstract

Nowadays, it is common to find IEEE 802.11 networks that are deployed in an unplanned and unmanaged manner. Moreover, because of the low hardware cost and, trying to obtain better coverage and performance, a large number of devices are usually installed in reduced spaces causing high-density deployments. This kind of networks experiment several problems related with the shared nature of the transmission medium. In recent years, different transmit power control mechanisms have been proposed to palliate those problems, however, in some situations, the existing solutions can lead to an starvation problem. In this paper, we present a novel mechanism that manages data rate, transmit power and carrier-sense threshold to reduce this problem.
