Interference Management with Energy Consumption Constraint in Heterogeneous Wireless Networks
In order to improve the network capacity and increase the coverage area, the future wireless networks will be heterogeneous networks, or HetNets, which are constituted by Macrocells and low-power nodes (LPNs), like Picocells, Femtocells. As a result, the interference in HetNets will be increasingly serious. In this paper, we first enhance the frequency reuse scheme to suppress the interference in HetNets. Then we propose a cooperative transmission scheme of LPNs to improve network capacity and reduce energy consumption. Simulation results show that, the proposed scheme can reduce the co-channel interference while increase the capacity of the network. Our scheme can also reduce energy consumption and improve the utilization of energy.
