An Energy Efficiency Channel Binding Mechanism for Multi-user MIMO in 802.11ac

In 802.11ac protocol, MU-MIMO technical is widely used for its excellent performance. In order to effectively save channel resources and decrease power consumption of the entire network, an Energy efficiency channel binding mechanism is proposed. The mechanism uses channel binding technology, binding two or more channels together, used to transmit the same data. Analysis and simulation results shown that the proposed method can get better power and channel resource utilities compared with other methods. It will be helpful to introduce a green network.
