中文摘要：

针对无人机自组网络多媒体数据传输中链路不稳定问题，提出了一种无人机自组网络多媒体数据传输路由算法。该算法在GPSR路由算法基础上，结合无人机多媒体通信的特点，充分考虑了位置、速度、运动方向这三个因素对选择下一跳节点的影响，从而达到同时兼顾三者和提高链路性能的目的。提出的算法具有开销小、可靠性高等优点，有效提高了分组交付率以及降低了平均端到端延迟，从而提高了无人机自组网络多媒体数据传输的性能。

英文摘要：

To solve the problem that link is instable in the UAV Ad hoc networks multimedia data transmis- sion, this paper proposes a routing algorithm for UAV Ad hoc networks multimedia data transmission. Based on the GPSR protocol and regarding the characteristics of the UAV multimedia communication, the algorithm take into account the impact of geographic information, speed and movement direction on the se- lection of the next node, so as to improve the link performance. The proposed algorithm, with its low link cost and high reliability, effectively improves the Packet Delivery Ratio and reduces the Average End-to-End Delay, thereby enhancing the performance of UAV Ad hoc networks multimedia data transmission.
