Dynamic Bandwidth Allocation Strategy for Marine VHF Communications

摘要

In order to achieve the efficient management of marine VHF communications bandwidth resources under the battlefield environment and to maximize the bandwidth utilization while ensuring high-priority business access channel, the context puts forward a kind of dynamic bandwidth allocation strategy based on business priorities. When the bandwidth resources are sufficient, the system can accommodate more business, otherwise it can call the dynamic allocation strategy in order to ensure high-priority business is processed. The simulation results show that this strategy can effectively reduce the blocking rate of the high priority business and can ensure high-priority business transmit timely and efficiently through releasing the business of low priority and using bandwidth seriously.
