摘要
时隙分配是影响战术数据链性能优劣的重要因素。混合时隙分配方式兼具固定和动态时隙分配的优点,是一种较为新颖的时隙分配思想,但在报文时延和冲突率方面还有优化空间。以时分多址(TDMA)模式的战术数据链为例,提出了一种基于优先级的混合时隙分配策略,并以排队论为基础构建了其报文传输模型,通过仿真研究不同优先级报文的时延特性,结果表明,该时隙分配策略能较好地适应报文突发率高的复杂战场环境。
Slot allocation is an important factor affecting the performance of tactical data link. Hybrid slot allocation method possesses both the advantages of fixed and dynamic slot allocation,which is a relatively new slot allocation thought,but still has optimization space in message time delay and collision rate. Taking the tactical data link（ TDMA） for example,the paper proposed a priority-based hybrid slot allocation,and built its message transmission model based on queue theory,finally through the simulation to research the time delay characteristics of messages at different priority levels,showing that the slot allocation policy can better adapt to the complex battlefield environment with high message burst rate.
