In order to ensure the strong real-time information sharing of Aerial Ad hoc Network, a low-delay information sharing algorithm for multiple-radio-per-platform networking is proposed based on the directional transmission capability of phased-array antenna. The algorithm introduces virtual nodes and virtual links in the process of topology generation first. By extracting topology information and choosing link grouping, it can effectively reduce redundant transmission and transmission latency of information sharing. Then, it is verified through simulation that the algorithm can reduce the latency by up to 49.8% and eliminate transmission redundancy. In addition, a direction selection algorithm is proposed for the variation of antenna beam direction. Simulation results show that the algorithm can further reduce the latency of information sharing and ensure the real time of information sharing, thus further improving the network performance.

为了保证空中自组网的实时信息共享能力强，基于相控阵天线的定向传输能力，提出了一种低延迟的多平台射频信息共享算法。该算法首先在拓扑生成过程中引入虚拟节点和虚拟链接。通过提取拓扑信息并选择链路分组，可以有效减少冗余传输和信息共享的传输时延。然后，通过仿真验证了该算法可以将等待时间减少多达49.8％，并消除了传输冗余。此外，针对天线波束方向的变化，提出了一种方向选择算法。
