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.
