摘　　要：水下无线传感器网络路由是水下物联网重要组成部分,可靠高效节能是水下无线传感器网络路由最关心的问题;针对水下无线传感器网络节点路由中能量消耗不均衡和过多冗余转发增加能耗而导致水下无线传感器网络生存周期缩短的问题,提出一种可调节转发区域的水下传感器路由协议(ESAFDBR);ESAFDBR路由协议考虑了当前节点深度和剩余能量,还考虑节点两跳邻域内信息,以这种方式有效减少网络遇到空洞的可能性,平衡网络能量;此外,为抑制冗余节点参与转发,设计划分转发区域,并可根据节点密集程度自适应调整划分区域,有效地提高网络性能。Underwater wireless sensor network routing is an important part of the underwater Internet of Things.Reliability,high efficiency and energy saving are the most concerned issues of underwater wireless sensor network routing.Aiming at the problem of unbalanced energy consumption in the routing of underwater wireless sensor network nodes and excessive redundant forwarding and increasing energy consumption,the life cycle of underwater wireless sensor networks is shortened.An underwater sensor routing protocol with adjustable forwarding area is proposed(An energy-saving underwater opportunistic routing protocol with adjustable forwarding area,ESAFDBR).The ESAFDBR routing protocol considers the current node depth and remaining energy,and also considers the information in the node's two-hop neighborhood.In this way,it effectively reduces the possibility of the network encountering holes and balances the network energy.In addition,in order to prevent redundant nodes from participating in forwarding,the division of forwarding areas is designed,and the divided areas can be adjusted adaptively according to the density of nodes,effectively improving network performance.
