一种新的多链路轮询方案
为了改善无人机数据链(unmanned aerial vehicle data link,UAV-DL)的吞吐量和平均时延,结合UAV的Markov飞行状态、Gilbert-Elliot信道模型和不同分组网络的优先级,提出了一种基于Gilbert-Elliot信道的UAV数据链多链路轮询策略.该策略以链路信道状态和不同分组网络的优先级为轮询的最优目标,首先,依据轮询的最优目标完成信息的传输,然后,依据排队过程的概率母函数和基本的排队原理分析了UAV数据链多链路轮询机制的性能.最后通过Opnet仿真了该策略组网条件下的平均时延和吞吐量,结果表明:与其典型的两种轮询方式相比,该方案的平均时延削减了至少30％,组网的吞吐量增加了1.3倍.
