| 摘 要： | 为在紧急救援和军事活动等实际应用中实现上下级间广播式通信方式, 参考并简化了 NbIA(Neighbors Indirect Acknowledgement Algorithm)算法的组网思路, 设计新的时隙分配方式, 提出了一种基于 TDMA(Time Division Multiple Address)的广播式 MAC(Media Access Control)算法。 OPNET 软件仿真结果表明, 该算法的组网速度与 NbIA 相近, 但实现方法大大简化, 并可根据节点的业务需求提升节点的吞吐率, 从而有效支持视频业务的传输。

| Abstract: | Between higher and lower communication mode, the type of propaganda is required to transmit video in broadcasting way in emergency situations and military applications especially. We propose a MAC(Media Access Control) algorithm with novel slot allocation way to ensure video transmission which refers to the idea in NbIA(Neighbors Indirect Acknowledgement Algorithm). Both proposed algorithm and NbIA are simulated using OPNET. The results show that former performs better in convergence time and throughput of single point. |
