Abstract :
This paper presents a distributed channel probing scheme for wireless networks. By transmitting a probing signal in a channel and measuring the signal-to-interference ratio (SIR), a wireless node can estimate channel admissibility and predict its required transmission power without fully powering up. The channel probing scheme can be used as part of a distributed channel allocation algorithm, and simulations have shown that it outperforms other schemes
