摘　　要：针对现有全双工通信MAC协议静态配对的不足,本文提出一种动态自配对MAC协议设计方案。该方案能够增大全双工无线通信的建立几率,避免通信冲突,提升频带利用率。仿真结果表明,与传统的半双工无线通信进行比较,动态自配对全双工无线通信MAC协议设计大大提高了网络吞吐量,降低了通信延时,且在降低用户间通信冲突方面有着显著的优势。In this paper,a new full duplex wireless communication Dynamic-self-pairing MAC protocol design is proposed to solve the shortages of the current Pre-pairing MAC protocol design.This design can not only increase the establishment chance of full duplex wireless communication,but also avoid communication conflicts and improve bandwidth utilization rate.Simulation results show that,the full duplex wireless communication Dynamic-self-pairing MAC protocol design exhibits a significant performance improvement comparing with conventional Pre-pairing MAC protocol design.It can effectively improve the throughput of network,reduce communication delay and avoid communication conflicts.
