A Channel Probing Scheme for Wireless Networks

Abstract

A channel probing scheme for wireless networks is presented. By transmittinga probing signal in a channel and measuring the signal-to-interferenceratio (SIR), a link can estimate the channel condition and predict therequired transmission power without fully powering up. The channel probingscheme can be used as part of a distributed channel allocation algorithm,and simulations have shown that it outperforms some other comparableschemes.
