摘要 针对无人机宽带数据链的组网特点和固定TDMA协议无法满足网络拓扑动态变化的缺点,引入按需分配机制,提出了一种能够支持QoS的DA-TDMA多址接入协议。利用Little定理和排队论等相关知识对协议性能进行了理论推导,重点研究了网络吞吐量和时延变化。最后利用OPNET对协议进行了仿真分析,结果表明,DA-TDMA协议能够很好地满足不同优先级业务共存条件下的时延和吞吐量要求。

英文摘要 This paper introduced the distribution according to need mechanism and proposed a new protocol supported QoS named DA-TDMA in allusion to the characters of UAV broadband data-link networking and shortcomings of the fixed TDMA which was unable to satisfy the changing of network topology. The performances of DA-TDMA, especially the throughput and delay changing were deduced theoretically according to the Little theorem and queuing theory etc. Finally, simulated the DA-TDMA protocol by OPNET. And results indicate that it can satisfy the throughput and delay demands fine with different priorities of packets.
