摘　　要：为了研究深空光通信骨干网媒体访问控制(MAC)协议,设计了深空光通信骨干网络,提出了一种扁平的无线Mesh深空光网络结构。结合激光通信的特点,对网络中的节点模型进行了多接口设计,并进一步提出了定向媒体访问控制(DMAC)协议。仿真结果表明:相比非定向媒体访问控制(NDMAC)协议,DMAC协议可有效改善网络性能。In order to research media access control(MAC)protocol in deep space optical communication backbone networks,the structure of deep space optical communication backbone networks is designed,and a flat wireless Mesh structure for deep space optical communication backbone networks is also proposed.Due to the sensitive characteristics of laser communications,this paper designs the node model with multiple interfaces,and the directional media access control(DMAC)protocol is proposed.Compared with non-directional media access control(NDMAC),DMAC protocol can effectively improve the performance of network.
