This paper proposes a novel estimation technique for dimensionality of deployed underwater sensor network (UWSN). In order to obtain the dimension, probing requests are sent from two anchor nodes (i.e., receivers), which are placed inside the network through buoy, to sensor nodes. Then, the sensor nodes transmit Gaussian signal as feedback to the anchor nodes. The cross‐correlation function (CCF) is determined of these Gaussian signals, which varies according to network dimension. As reference, analytical CCF of five reference networks of different dimensions is determined. Thereafter, by comparing the CCFs of unknown and reference UWSN, cost function (CF) is obtained. The lowest value of CF attained by the specific combination of the one reference and the unknown network indicates that the dimension of these networks is identical. The dimension of two unknown deployed networks is investigated to demonstrate the feasibility of the proposed technique. From the illustrated results, it is justified that the new strategy can provide correct information about the dimension of the deployed network.

使用成本函数确定未知部署的水下传感器网络（UWSN）的维数
本文提出了一种新的部署水下传感器网络（UWSN）维数估计技术。为了获得尺寸，将探测请求从两个锚点（即接收器）通过浮标放置在网络中，发送给传感器节点。然后，传感器节点将高斯信号作为反馈传输到锚点。这些高斯信号的互相关函数（CCF）由网络尺寸决定。作为参考，确定了五个不同维度的参考网络的分析CCF。之后，通过比较未知和参考UWSN的CCF，可以获得成本函数（CF）。通过一个参考和未知网络的特定组合获得的CF的最小值表明这些网络的尺寸相同。研究了两个未知部署网络的维度，以证明所提出技术的可行性。从说明的结果可以证明，新策略可以提供有关已部署网络规模的正确信息。
