Abstract

For active, probing-based bandwidth measurements performed on top of the unifying IP layer, it may seem reasonable to expect the measurement problem in wireless networks to be no different than the one in wired networks. However, in networks with 802.11 wireless links we show that this is not the case. We also discuss the underlying reasons for the observed differences.Our experiments show that the measured available bandwidth is dependent on the probe packet size (contrary to what is observed in wired networks). Another finding is that the measured link capacity is dependent on the probe packet size and on the cross-traffic intensity.The study we present has been performed using a bandwidth measurement tool, Diet Topp, that we have developed. DietTopp measures the end-to-end available bandwidth of a network path along with the capacity of the congested link.
