在本文中，我们提出了一种分布式数据收集方案，使用一个自主水下航行器（AUV）作为一个移动的汇收集数据从一个随机分布的水下传感器网络传感器节点聚集在几个簇头。不同于传统的数据收集方案，其中AUV访问每个节点或每个簇头，该方案允许AUV访问一些选定的节点命名的路径节点的方式，降低了传感器节点的整体传输功率。Monte Carlo模拟进行调查的性能相比，所提出的方案采用AUV的能源消耗总量，每个节点的能源消耗的标准偏差，延迟收集数据在一个汇，和控制开销方面的几个预先存在的技术。仿真结果表明，该方案不仅降低了总能耗，而且使能耗在网络中分布更加均匀，从而延长了网络的生命周期。
In this paper, we propose a distributed data-gathering scheme using an autonomous underwater vehicle (AUV) working as a mobile sink to gather data from a randomly distributed underwater sensor network where sensor nodes are clustered around several cluster headers. Unlike conventional data-gathering schemes where the AUV visits either every node or every cluster header, the proposed scheme allows the AUV to visit some selected nodes named path-nodes in a way that reduces the overall transmission power of the sensor nodes. Monte Carlo simulations are performed to investigate the performance of the proposed scheme compared with several preexisting techniques employing the AUV in terms of total amount of energy consumption, standard deviation of each node’s energy consumption, latency to gather data at a sink, and controlling overhead. Simulation results show that the proposed scheme not only reduces the total energy consumption but also distributes the energy consumption more uniformly over the network, thereby increasing the lifetime of the network.
