摘　　要：Ad Hoc网络无中心、自组织、动态拓扑且支持多路径通信,适合无人机组网。传统单信道MAC协议难以解决Ad Hoc网络中的隐藏终端和暴露终端问题,影响数据传输。本文探讨多信道MAC协议原理及其优劣性,通过OPNET平台对多信道MMAC协议和单信道IEEE 802.11DCF协议进行仿真。实验显示,MMAC协议在解决隐藏终端和暴露终端问题上表现卓越,且在吞吐量和丢包率等网络性能指标上优于单信道IEEE802.11协议。Ad Hoc networks are characterized by their lack of central control,self-organization,dynamic topology,and support for multi-path communication,making them suitable for networking in UAVs.Traditional single-channel MAC protocols struggle to address the hidden and exposed terminal problems in Ad Hoc networks,which impact data transmission.This paper explores the principles of multi-channel MAC protocols,their advantages and disadvantages,and simulates multi-channel MMAC protocols and single-channel IEEE 802.11 DCF protocols using the OPNET platform.The experiments indicate that the MMAC protocol excels in resolving hidden and exposed terminal issues and outperforms the single-channel IEEE802.11 protocol in terms of network performance metrics such as throughput and packet loss rate.
