Adaptive Power Control in 802.11 Wireless Mesh Networks
Adaptive power control is an actual research topic due to its use for energy saving and for improving network capacity in wireless mesh networks. By varying the transmit power level, the signal quality is affected, consequently determining which neighboring nodes can receive the packets. In this paper, the authors propose a new power control technique that adapts the transmissions based on the neighboring active links. It is evaluated alongside with other methods, described in the literature, for improving network capacity. They show, by simulation, that their method can improve the network throughput by up to 30% compared to the IEEE 802.11 standard MAC in a grid topology.
