Chen Weijie · Jisuanji gongcheng · 2011
By dividing links between nodes into forward link and reverse link,this paper presents a hybrid channel assignment strategy based on node interference in Multi-radio Multi-channel(MRMC) Wireless Mesh Network(WMN).It analyzes link interference through probability model,computes link weight between nodes,and establishes directed network connection graph with weight.The channel of fixed interface on node is assigned according to link weight,in order to decrease network interference in the process of channel switching.Simulations result of extensive NS2 shows that this method can improve the link interference and network throughput effectively.
