Optimization Algorithm of Control Channel Selection for Wireless Networks

摘要

Control channel is used to transmit protocol or signal information between wirelessnetwork nodes and is a key component of wireless network. Compared with data information,protocol or signal information is usually much less, so the spectrum bandwidthrequirement of control channel is also much less than that of data channel. In order to optimizethe usage of the limited spectrum resources, this paper focuses on the issue of controlchannel selection. We propose a greedy algorithm which minimizes the total spectrumbandwidth of the set of control channels. Theoretical analysis proves that the proposed algorithmcan achieve the optimal set of control whose sum of the spectrum bandwidthis the minimum. Simulation results also show that the proposed algorithm consumesless spectrum resources than other algorithms in the same wireless network environment.
