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.
