摘要：
Available bandwidth estimation is a vital component of admission control for quality-of-service (QoS) in networks, it seek to provide an accurate estimation of available bandwidth such that network applications can adjust their behavior accordingly. Wireless ad hoc networks employing the IEEE 802.11 protocol in Distributed Coordination Function (DCF) mode are becoming increasingly popular. In this paper, an available bandwidth estimation scheme for IEEE 802.11-based ad hoc network is presented. Our scheme does not modify the CSMA/CA MAC protocol in any manner, but gauges the effect of phenomena such as medium contention, channel interference, which influence the available bandwidth, on it. Based on the effect of the phenomena on the working of the medium-access scheme, we estimate the available bandwidth of a wireless host to each of its neighbors. The result of simulation shows that the scheme is efficiently.
