微型无人机群空空数据链协议建模与仿真

为较为准确、客观地评价微型无人机群（UAV：Unmanned Aerial Vehicles）空空数据链系统的各项性能指标,根据ZigBee（Zig＋Bee无线数传网络）协议,通过建立时隙轮询表完成时隙分配。在简要分析ZigBee协议栈各层的功能及其网络拓扑结构的基础上,重点阐述了空空数据链协议的时隙分配机制及网络地址分配机制,讨论了利用网络仿真工具OPNET（Optimized Network Engineering Tools）建立该无线通信协议模型的过程,并通过构建一个网络仿真平台对信道接入延时、吞吐量等进行仿真分析。验证了该空空数据链采用的通信协议的有效性,同时也为其他网络协议仿真提供了参考。

Protocol Modeling and Simulation for MAV Group Air to Air Data Link

For UAV（Unmanned Aerial Vehicles） group air to air data link of wireless communications,in accordance with the ZigBee protocol,through the establishment of slot polling table the slot allocation is completed.After a brief analysis of the ZigBee protocol stack layers of functionality and the use of the network topology based on a focus on the data link protocol air to air data link slot allocation mechanism and the network address allocation mechanism.Discuss how to use OPNET（Optimized Network Engineering Tools） network simulation tool to create this model of wireless communication protocol process,and by constructing a network simulation platform for the channel access delay,throughput,etc.of the simulation analysis to verify this air to air data link communication protocols used the validity of this simulation for other network protocols as a reference.
