摘　　要：近年来,水下物联网和海洋物联网已经成为一个热门的研究方向,水声传感器网络路由协议作为海洋物联网的重要组成部分也得到研究人员的广泛重视。因此在HH-VBF协议的基础上,提出一种基于矢量转发的节能型水声传感器网络路由协议——ES-HH-VBF协议。ES-HH-VBF协议在保留了将下一跳节点的位置信息作为计算节点转发因子的参考值的基础上,引入了节点剩余能量改进节点转发因子的计算方式,以此来均衡网络中的能量消耗;并且还将预设的距离阈值由HH-VBF协议中的固定值改为根据节点剩余能量变化的动态值,从而可以动态地控制数据冗余。为了验证ES-HH-VBF协议的性能,在水下传感器网络仿真器Aqua-Sim上对HH-VBF协议和ES-HH-VBF协议的性能进行了对比分析。仿真结果表明,随着节点发包间隔的增加,ES-HH-VBF协议的包传递率比HH-VBF协议的包传递率高4.2%左右,网络平均时延比HH-VBF协议低11.3%左右,网络平均能耗比HH-VBF协议低8.2%左右。通过对ES-HH-VBF协议和HH-VBF协议的仿真实验分析可知,ES-HH-VBF协议在提高数据包传递率、降低平均能耗和降低平均延时方面具有较大优势。In recent years,underwater Internet of Things and marine Internet of Things have become a hot research direction.As an important part of marine Internet of Things,the routing protocol of underwater acoustic sensor networks has also received extensive attention from researchers.Therefore,based on HH-VBF(hop-by-hop vector-based forwarding)protocol,this paper proposed an energy-saving routing protocol for underwater acoustic sensor networks called ES-HH-VBF(energy-saving hop-by-hop vector-based forwarding)protocol.ES-HH-VBF protocol kept the location information of the next hop node as the refe-rence value for calculating the node forwarding factor,and introduced the remaining energy of the node to improve the calculation method of the node forwarding factor,so as to balance the energy consumption in the network.And this paper also changed the preset distance threshold from the fixed value in HH-VBF protocol to the dynamic value based on the change of node residual energy,thereby dynamically controlling data redundancy.In order to verify the performance of ES-HH-VBF protocol,this paper compared and analyzed the performance of HH-VBF protocol and ES-HH-VBF protocol on the underwater sensor network simulator Aqua-Sim.The simulation results show that,with the increase of packet transmission interval between nodes,the packet delivery rate of ES-HH-VBF protocol is about 4.2%higher than that of HH-VBF protocol,the average network delay is about 11.3%lower than that of HH-VBF protocol,and the ave-rage network energy consumption is about 8.2%lower than that of HH-VBF protocol.Through the simulation analysis of ES-HH-VBF protocol and HH-VBF protocol,it shows that ES-HH-VBF protocol has great advantages in improving packet delivery rate,reducing average energy consumption and average delay.
