摘要/Abstract

摘要： 基于无人平台集群的分布式协同作战是未来战争的发展趋势，由此对智能集群无线自组网通信提出了快速响应的性能需求。针对现有无线自组网分布式多址接入机制在复杂多变战场环境与时断时续通信链路中存在的效率下降、无法满足快速响应需求的问题，提出基于分布式协同的编码域多址(DC-CMA)机制。DC-CMA机制以分布式无线自组网邻居节点信息维护与非正交多址技术为基础，设计高效的接入编码图样，通过降低图样稀疏性减少资源浪费，提高多址机制整体资源效率。数值仿真结果表明，在信道中断率相同时，与正交多址机制相比，DC-CMA机制可将信息交互周期缩短10%~50%，提升通信资源效率达5%~30%。利用无线自组网节点设备样机，模拟分布式协同任务数据进行端到端传输时延测试，得出DC-CMA机制相比于正交多址机制可降低平均传输时延超过30%，能够为提升无人平台集群分布式快速响应协同能力提供支撑。

Abstract: Distributed cooperative operations of unmanned platform swarms is the trend of future warfare, which calls for rapid response of the intelligent swarm network. However, there is little research on the analysis of wireless swarm ad-hoc networks and distributed multiple-access schemes with intermittent links in complex and dynamic battlefield environments. To this end, a novel distributed coordinated coded multiple access (DC-CMA) scheme is proposed based on non-orthogonal multiple access techniques. The access code pattern of nodes is more efficient than the ones in previous schemes by reducing sparsity and minimizing the waste of resources. Numerical simulation results show that the proposed DC-CMA scheme can reduce the scheme period duration by 10% to 50% compared to the orthogonal multiple access scheme, and improve the resource efficiency by 5% to 30%. An end-to-end transmission delay test is carried out by using the prototype of wireless ad-hoc network nodes to simulate the distributed collaborative task, and the test results show that the DC-CMA scheme can decrease the mean transmission delay by more than 30%, which supports the rapid response of the distributed cooperative intelligent unmanned swarms.
