Research on dynamic performance regulation method of bidirectional relay network based on SDN architecture

Abstract

In order to overcome the shortcomings of the traditional dynamic regulation methods of bidirectional relay network, such as low resource utilisation and high energy consumption of nodes, a dynamic regulation method of bidirectional relay network performance based on SDN architecture is proposed. SDN architecture is used to construct the bidirectional relay network model. The subcarrier pairing algorithm is used to pair the subcarriers, and then the model of two-way relay network is optimised. The optimal configuration of node power and subcarrier power is carried out respectively, and the joint energy consumption control model of two-way relay network is constructed by using game theory. In this way, the performance of bidirectional relay network can be dynamically adjusted. Through experiments, compared with the traditional method, the proposed method improves resource utilisation, reduces node energy consumption and has better performance.
