摘　　要：为了尽量节省深空光网络节点的能量,提出定向洪泛路由算法(DFRA),该算法根据深空光通信对角度和方位的敏感特性,基于多接口的深空节点模型,将空分复用和频分复用充分结合,支持定向的多跳路由传输,路由寻路的过程中只有部分节点参与。仿真分析结果表明:与传统洪泛路由算法(TFRA)相比,DFRA能够避免TFRA存在的无方向性和盲目性的问题,更加节能,且网络传输时延和时延抖动等性能都优于TFRA方法。In order to save as much as possible of deep space optical network node energy, directional flood routing algorithm(DFRA), the algorithm is based on deep space optical communication is sensitive to angle and azimuth of features, based on the deep space node model of the interface, will air separation combination of reuse and frequency division multiplexing, supports the transfer of multiple hops routing orientation, in the process of the routing path finding only part of the nodes involved. The simulation results show that, compared with the traditional flood routing algorithm(TFRA), DFRA can avoid the non-directionality and blindness problems existing in TFRA, and is more energy efficient, and the performance of network transmission delay and delay jitter is better than TFRA.
