Research on MAC Layer Resource Scheduling Algorithm of Air Mobile Ad Hoc Network Based on TDM A
Air wireless mobile Ad hoc network(MANET)is a multi-hop centerless network with rapidly changing topology and self-organization.Aiming at the problems of low resource utilization,insufficient throughput and short communication distance of tra-ditional time-slot allocation algorithm,an orientation distribution resource dynamic scheduling algorithm(M-TDMA)based on time division multiple access(TDMA)is proposed by combining the node service priority and traffic prediction and introducing the distribu-tion coefficient to the hybrid time-slot allocation mode.The effects of multiple dimensions such as the number of nodes,transmission rate,distribution coefficient and different topologies on the transmission delay,throughput,and packet loss rate are compared and an-alyzed.Finally,the resource scheduling algorithm is verified by the simulation experiment.The simulation results show that when there are 20 network nodes,the maximum transmission delay of the network is less than 600 ms,and the network throughput can reach more than 4.5 Mbps.The M-TDMA algorithm can effectively reduce the network transmission delay and improve the network throughput through the efficient resource scheduling.
