A QoS Guarantee Based Hybrid Media Access Control Protocol of Aeronautical Ad Hoc Network

In order to meet different data rate and timeliness requirements of different services in aeronautical network communications based on frequency and time-hopping mechanism, a hybrid media access control protocol based on pre-allocation of transmission time slots and immediate access is proposed. It is based on network capacity simulation analysis of burst service frames, channel immediately access capability is reserved for high-priority service frames, and time slot pre-allocation strategies and network access permissions are designed for middle- and low-priority service frames. Time sensitive demand of high-priority service frames is guaranteed, and transmission of middle- and low-priority service frames to the greatest extent is ensured at the same time. The simulation results verify the effectiveness of the protocol.
