摘要: 在飞行自组网中,固定时隙分配时分多址接入(TDMA)协议存在闲置时隙无法成功使用的问题。通过对TDMA协议引入闲置时隙预约机制,提出一种支持业务优先级传输机制的闲置时隙预约TDMA协议。采用短帧长的方式满足协同与控制业务的低时延传输需求,并利用闲置时隙预约机制允许节点使用闲置时隙传输感知业务,从而满足感知业务的高吞吐量传输性能要求。仿真结果表明,与CF-MAC和CTMAC协议相比,该协议能够在降低传输时延的同时,有效提高信道利用率和网络吞吐量。

Abstract: In the Flying Ad-Hoc Networks(FANets),the fixed time slot allocation Time Division Multiple Access(TDMA) protocol has the problem that the idle time slot cannot be used successfully.By introducing an idle time slot reservation mechanism to the TDMA protocol,this paper proposes a TDMA protocol for idle time slot reservation that supports the service priority transmission mechanism.Short frame length is adopted to meet the low delay transmission requirements of cooperative and control services.The idle time slot reservation mechanism is used to allow nodes to use idle time slots to transmit sensing services to meet the high throughput transmission performance of sensing services.Simulation results show that compared with CF-MAC and CTMAC protocols,the proposed protocol can effectively improve channel utilization and network throughput while reducing transmission delay.

Key words: Unmanned Aerial Vehicle(UAV) cluster, Flying Ad-Hoc Networks (FANets), fixed time slot allocation Time Division Multiple Access(TDMA), network throughput, idle time slot
