Tuning a mid-range rural WiFi-based mesh network

Abstract

Little is known about how mid-range, or several km, dis- tances a ect multipoint-to-multipoint links when single ra- dio nodes with omnidirectional antennas are used. In this poster, a real network with these characteristics is described and empirical results of its performance are presented. In particular, the e ect of increasing the SlotTime value for optimizing the aggregated throughput has been analyzed. Results show the need to increase the SlotTime to consider- ably bigger values than those oberved for point-to-point and point-to-multipoint long-range links. With the new value of SlotTime, an increase of 115% in aggregated throughput was obtained over the standard Slottime value.
