Underwater wireless sensor networks are currently seeing broad research in various applications for human benefits. Large numbers of sensor nodes are being deployed in rivers and oceans to monitor the underwater environment. In the paper, we propose an energy-efficient clustering multi-hop routing protocol (EECMR) which can balance the energy consumption of these nodes and increase their network lifetime. The network area is divided into layers with regard to the depth level. The data sensed by the nodes are transmitted to a sink via a multi-hop routing path. The cluster head is selected according to the depth of the node and its residual energy. To transmit data from the node to the sink, the cluster head aggregates the data packet of all cluster members and then forwards them to the upper layer of the sink node. The simulation results show that EECMR is effective in terms of network lifetime and the nodes' energy consumption.
水下无线传感器网络目前正在广泛研究各种造福人类的应用。大量传感器节点被部署在河流和海洋中，以监测水下环境。在本文中，我们提出了一种节能聚类多跳路由协议（EECMR），该协议可以平衡这些节点的能量消耗并延长其网络寿命。网络区域根据深度级别划分为层。节点感知到的数据通过多跳路由路径传输到汇聚节点。簇头根据节点的深度及其剩余能量进行选择。为了将数据从节点传输到汇聚节点，簇头聚合所有簇成员的数据包，然后将它们转发到汇聚节点的上层。仿真结果表明，EECMR在网络寿命和节点能量消耗方面是有效的。
