End to end available bandwidth is often constrained by IEEE 802.11 hops in the access network. Available bandwidth measurement is particularly challenging in the wireless environment because of adaptive data rates, a time varying channel, and CSMA/CA based contention instead of simple FIFO queueing. We present a novel estimation scheme for IEEE 802.11 networks in infrastructure mode, based on passive...
In this paper, we study bandwidth management of a wireless/optical based access/metro network in support of voice and data services. For voice services, we use a finite state Markov Chain to estimate the blocking probability of voice circuits over an Adaptive modulation and coding wireless channel, as a function of the channel parameters. For data services, we evaluate a rate matching and a buffer...
