Accurate assessment of the available link bandwidths in wireless networks is crucial for applications to negotiate, adapt and control quality-of-service parameters. In this paper we focus on new methods for estimating/predicting saturated throughputs (link bandwidths) in 801.11b wireless local area networks (WLANs). We propose the principle component analysis (PCA) and clustering approach for the estimation problem and the pattern modeling and recognition system (PMRS) and method of moment matching (MM) for the prediction problem. A trade off between the complexity and accuracy of the estimation/prediction algorithms is discussed and compared with the Neural Networks (NN) approach.
