摘　　要：传统的空间信息网络在进行数据传输过程中,因受到空间传感器节点存储空间的影响,收集和传输的数据量受到较大限制,无法满足现有传感器节点与空间信息网络互联的迫切需求。为此,提出一种空间信息网络吞吐量优化的方法,对空间传感器传输频谱重新进行分配,然后计算出空间信息在传输信道中相互干扰的宏信息和超微数据信息,按不同信道和不同数据选择不同的接入方式进行数据传输,通信信道通过优化模型加入限制数据传输条件,避免在同一空间内各相近的网络信息传输使用相同信道,并且在相似数据传输之间采用频道共享方案,进一步提升空间信息网络吞吐量。仿真结果表明,改进的空间信息网络吞吐量优化方法能够提升数据传输效率,解决了传统方法单一信道传输受限,网络吞吐量低的问题,同时保证了空间信息网络传输的服务质量,在实际工作生活中具有一定的应用价值。A throughput optimization method of space information network is proposed. Firstly, the transmission frequency spectrum of space sensor is allocated anew. Then, the macros information and supermicro data information of space information interfered with each other in transmission channel are obtained, and different access ways to transmit data are selected according to different channels and data. Moreover, the restriction condition of data trans- mission is added into transmission channel through optimization model. Thus, the similar network information can be avoided to use the same channel in identical space. Finally, the channel share scheme between similar data transmission is used and further throughput of space information network is improved. The simulation results show that the modified method can improve data transmission efficiency and overcomes the limitation of single channel and low network throughput in traditional method. In the meantime, the transmission service quality of space information network is ensured.
