摘　　要：针对水声通信现有的CSMA协议网络吞吐量较低,利用时间和空间重用,增加并发传输的机会来补偿长传播延迟,提出一种延迟传输调度算法,通过检测相邻节点传播延迟及其预期信息进行传输调度,降低节点暴露冲突的可能性,提高水声通信无线自组织网络吞吐量。通过仿真对比分析,该算法可以显著提高整体吞吐量,有效地处理由物理位置和传播延迟引起的空间不公平性。In view of the low throughput of the existing CSMA protocol network in underwater acoustic communication,a delay transmission scheduling algorithm is proposed to compensate the long propagation delay by using time and space reuse and increasing the chance of concurrent transmission.By detecting the propagation delay of adjacent nodes and their expected information,transmission scheduling can reduce the possibility of nodes exposing conflicts and improve the throughput of wireless self-organizing network for underwater acoustic communication.Through simulation and comparative analysis,this algorithm can significantly improve the overall throughput and effectively deal with spatial inequity caused by physical location and propagation delay.
