摘　　要：为了提高网络吞吐量,降低网络能耗,改善数据传输延时,研究水声通信网络超低传输延迟控制方法。基于S-MAC协议设计了更适用于水声通信网络的功率控制PC-CSMA/CA协议,通过CSMA/CA的Rts/Cts预约自适应调整数据包传输功率,在PC-CSMA/CA协议的基础上提出了一种传输调度算法,通过检测相邻节点传输延迟及其预期信息优化传输性能,降低节点暴露冲突的发生,全面改进水声通信网络性能。实验结果表明:该方法应用后,可显著提升不同分组间隔下的网络吞吐量、降低网络平均损耗,具备较好延迟控制能力和控制实时性。In order to improve network throughput,reduce network energy consumption and improve data transmission delay,ultra-low transmission delay control method for underwater acoustic communication network was studied.Based on the S-MAC protocol,a power control PC-CSMA/CA protocol was designed,which is more suitable for underwater acoustic communication network.The packet transmission power was adjusted adaptively through the RTS/CTS reservation of CSMA/CA.a transmission scheduling algorithm is proposed based on PC-CSMA/CA protocol.The transmission performance was optimized by detecting the transmission delay and expected information of adjacent nodes,reducing the occurrence of node exposure conflicts and comprehensively improving the performance water acoustic communication network performance.The experimental results show that the proposed method can significantly improve the network throughput and reduce the average network loss under different packet intervals,and has good delay control ability and real-time control.
