摘要
为了实现多导弹成员对无线信道的共享,以时分多址(TDMA)模式的战术数据链为基础,提出了一种基于优先级的混合时隙分配算法。算法按照节点的数目分配固定时隙,保证了每个成员基本业务和申请要求的基础,同时根据节点和业务特点划分优先级,并按照综合优先级的高低进行动态的分配时隙资源。仿真结果表明,上述算法与固定时隙分配算法和动态时隙分配算法相比较,不仅有更低的时延和更高的吞吐量,而且保证低优先级业务服务质量,更能适应节点数目变化的情况。
In order to realize the sharing of wireless channels among the multi-missile members, a hybrid slot allocation algorithm was proposed based on priority and the tactical data link of time division multiple access (TDMA) mode. The algorithm conducted allocation according to the number of nodes, which ensures the basic operation and application requirements of each member. At the same time, the priority was divided according to the node and service characteristics, and time slot resources was allocated dynamically in terms of the level of the integrated priority. The simulation results show that compared with the fixed slot allocation algorithm and the dynamic slot allocation algorithm ,this algorithm not only has lower latency and higher throughput, but also ensures the service quality of low priority services, and is more adaptable to the change of the number of nodes.
