摘　　要：针对当前主流Mesh自组网技术节点传输带宽不足百兆,级跳数小于10的问题,提出采用多处理器构建实现分布式多跳、高带宽低时延的无线跳频的高性能自组网节点,对节点自动化组网连接、多信道选择避让、漫游切换及低时延高带宽网络多跳实现等关键技术进行研究实现。由测试结果分析可知,在20级跳内,文中节点组网带宽损失在30%以内且带宽保持在200 Mb/s以上,时延控制在100 ms内,可以满足现实应急场景下多终端智能硬件实时进行图像、视频等大数据量信息交互对高带宽低时延网络通信的需求。In response to the current mainstream mesh ad hoc network technology,where the transmission bandwidth of nodes is less than 100 megabytes and the number of hops is less than 10,a high⁃performance ad hoc network node with distributed multi hop,high bandwidth and low latency wireless frequency hopping is constructed with multiple processors.Key technologies such as node automation network connection,multi⁃channel selection avoidance,roaming switching,and multi hop implementation in low latency and high bandwidth networks are studied and implemented.According to the analysis of test results,it is known that within 20 hops,the bandwidth loss of nodes network is kept within 30%and its bandwidth is kept above 200 Mb/s,and its delay is kept within 100 ms,so it can meet the demand of high bandwidth and low delay network communication for real⁃time image,video and other big data information interaction of multi terminal intelligent hardware in emergency scenarios.
