针对微小型无人机通信中继平台的特殊性,提出了一种符合该应用场景的动态优先级带宽分配算法。该算法基于TDMA,通过具有路由发现能力的控制端收集支路路由优先级信息,据此实现带宽的动态分配,并当某些节点时延超出限度时自动提升其支路路由优先级。试验证明,该算法减小了系统开销,动态提高了热点节点的吞吐量,降低了系统平均时延,较好地满足了作战要求。 According to the particularity of the communication platform of the UAV, a dynamic priority bandwidth allocation algorithm is proposed. Based on TDMA, this algorithm collects the routing priority information through the control end with the ability of route discovery. Based on this, the dynamic allocation of bandwidth is realized and the routing priorities of some branches are automatically increased when the delay of some nodes exceeds the limit. Experiments show that this algorithm reduces the system overhead, dynamically increases the throughput of hot nodes, reduces the average system delay, and better meets the operational requirements.
