The channel allocation is one of the key problems in the design of the wireless network, as it greatly influences the throughput and performance of the network. Firstly the authors introduce the channel propagation model, which is able to accurately reflect the signal attenuation, the network interference and other factors in the actual environment. Based on this paper, they put forward the channel allocation algorithm named LRCAA, which includes two parts: the pre-allocation stage and the dynamic optimization stage. The LRCAA is verified by the experiment, which shows it can converge to a stable optimal point and obtain a better network performance.
