A novel dynamic bandwidth management mechanism based on the traffic prediction is presented to solve the problem of long delay caused by traditional demand assigned multiple access (DAMA). Firstly, the satellite terminals predict the queue length of the buffer, then send the reports to the network control center (NCC). Finally, the resources are allocated to the terminals by NCC. The algorithm performance is validated through the simulation for different types of traffic and different intervals between two consecutive prediction reports. The priority of real time traffic is considered. The delays of DAMA based on prediction and normal case are compared. The theoretical analysis and simulation results show that the new DAMA algorithm can efficiently tackle the problem of delay between bandwidth request and bandwidth assignment. [ABSTRACT FROM AUTHOR]
