The energy-efficient and reliable delivery of data packets in resource constraint underwater wireless sensor networks (UWSNs) is one of the key considerations to enhance the network lifetime. The traditional re-transmissions approach consumes the node battery and increases the communication overhead, which results in congestion and affects the reliable data packet delivery in the network. To ensure the reliability and conserve the node battery, in this paper, we propose adaptive forwarding layer multipath power control routing protocol to reduce the energy dissipation, achieve the data reliability and avoid the energy hole problem. In order to achieve the reliability, tree based topology is exploited to direct multiple copies of the data packet towards the surface through cross nodes in the network. The energy dissipation is reduced by a substantial amount with the selection of low noise path between the source and the destination including the information of neighbors of the potential forwarder node. Extensive simulation results show that our proposed work outperforms the compared existing scheme in terms of energy efficiency and packet received ratio (PRR).
在资源受限的水下无线传感器网络（UWSN）中，高效节能且可靠地传输数据包是延长网络寿命的关键考虑因素之一。传统的重传方法会消耗节点电池电量并增加通信开销，这会导致拥塞并影响网络中数据包的可靠传输。为确保可靠性并节省节点电池电量，在本文中，我们提出了自适应转发层多路径功率控制路由协议，以减少能量消耗，实现数据可靠性并避免能量空洞问题。为了实现可靠性，利用基于树的拓扑结构，通过网络中的交叉节点将数据包的多个副本导向水面。通过选择源节点和目的节点之间的低噪声路径（包括潜在转发节点的邻居信息），可大幅降低能量消耗。大量仿真结果表明，我们提出的方案在能量效率和数据包接收率（PRR）方面优于现有的对比方案。
