摘　　要：减少数据包碰撞,节省能量,保持收发数据的同步性是水声网络MAC层协议设计的关键策略。本文在一种已有的UWAN-MAC协议的基础上展开研究,提出了一种改进的UWAN-MAC协议,该协议在不影响节点同步的前提下,通过优化节点的收发数据包机制,可以获得更低的碰撞率和更高的节能效果。最后通过仿真对原协议和修改后的协议进行了比较和分析。Reducing the collision of data packets,saving node＇ s energy and holding the synchronization of transmit and receive data are the key strategies of the MAC protocol for underwater acoustic networks. Based on the existed UWAN-MAC protocol, an improved UWAN-MAC protocol has been proposed in this paper. This protocol can obtain lower collision ratio and higher energy saving effect by optimizing node＇ s mechanism of transmit and receive data packets. Finally ,we compare the improved protocol with the original protocol and analyze the results by simulation.
