Underwater acoustic sensor networks (UASNs) play a crucial role in marine data collection. However, due to harsh underwater channel conditions and the finite energy supply of sensor nodes, underwater data transmission faces difficulties such as low reliability, limited spectrum, and constrained energy resources. How to ensure the performance of UASNs, such as network lifetime and energy efficiency (EE), under limited resources is a critical problem that needs to be addressed. To tackle these challenges, a matching game-based approach for relay selection and power allocation is proposed in this paper. Specifically, we model the network lifetime maximization (NLM) problem under resource constraints as a matching game problem, and develop an iterative matching algorithm based on NLM to ensure stable outcomes for relay selection and power allocation. Additionally, we devise a power allocation algorithm focused on energy efficiency to enhance system EE while guaranteeing NLM. The simulation results show that the proposed strategy greatly surpasses other benchmark algorithms in extending network lifetime and optimizing EE, validating its effectiveness and practicality. © 2001-2012 IEEE.

An adaptive optimal consensus control design technique is presented for uncertain multiagent systems with prescribed performance guarantees using reinforcement learning (RL) algorithm. First, an adaptive neural network identifier is employed to learn the knowledge of uncertain system dynamics, and a disturbance observer is developed to compensate for time-varying disturbances. Second, a critic-network learning structure is established to obtain the approximate solution of Hamilton-Jacobi-Bellman (HJB) equations of multiagent systems. Then, an experience replay method is applied to update the critic network weights without requiring persistence of excitation condition. Third, RL-based optimized consensus controllers are developed such that 1) the cost function is minimized, 2) transient and steady-state performances of consensus error systems are guaranteed, and 3) uniform ultimate boundedness of the closed-loop systems is achieved. Finally, application to consensus control of unmanned surface vehicles with uncertain hydrodynamic dampings is given to demonstrate the effectiveness of the optimal control design technique. © 2020 IEEE.

The technology for non-contact vibration measurement using video recorded by cameras has rapidly developed in recent years, however, existing methods are unable to effectively handle unstable video sources. This paper proposes a phase vibration measurement algorithm based on digital image stabilization, which employs the Kanade–Lucas–Tomasi feature tracking method to track feature points in the input video and derive affine transformation matrices between adjacent frames. Additionally, it utilizes the random sample consensus algorithm to eliminate outliers and smooth motion trajectories, applies the Hilbert transform to extract the global phase information of the stabilized video, uses the amplitude information to weight the phase information, and designs an adaptive filter to remove noise. Numerical simulations and experiments demonstrate the effectiveness and accuracy of the proposed method. © 2024 SPIE.

The problem of load imbalance in Underwater Wireless Sensor Networks (UWSNs) can cause some nodes to overload, resulting in a decrease in the performance of the entire system. This paper proposes a Q-learning-based load balancing routing (QLBR) protocol. QLBR introduces a load balancing mechanism into the Q-learning-based routing protocols, which predicts the load situation based on the forwarding count of nodes to candidate forwarding nodes, thereby better distributing routing load evenly in the network. By balancing the load, QLBR reduces the risk of node failures caused by overuse and improves the overall efficiency and reliability of data transmission in UWSNs. Simulation results demonstrate that QLBR significantly enhances the transmission efficiency of data packet and performance well in terms of end-to-end delay and energy consumption. © 2024 IEEE.

This paper studies the small sample target detection based on SAR images. Aiming at the problem of target semantic information loss in small sample targets, the residual network structure is optimized and improved based on YOLOv3 algorithm, and the data enhancement method is used to increase the number of small sample ships in the dataset. In this paper, three different ship detection data sets are processed, and the public datasets of multi-source SAR satellite ground object types are classified according to the different shooting satellites and polarization methods. A total of ten standard VOC datasets suitable for different algorithms are produced. In this paper, the constructed algorithm is compared with three comparison algorithms. The results show that although the detection performance of YOLOv3 is better than that of RCNN series, the detection accuracy of the two for small sample targets needs to be improved. Aiming at the small sample ship target with complex background in the data set, the detection effect of our algorithm is better. The mAP is used to verify the detection accuracy. The results show that the improved algorithm’s mAP is 2% higher than others. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Aiming at the problem that the monitoring area of the underwater wireless sensor networks (UWSNs) gradually decreases with the death of sensor nodes, this paper proposes a coverage-preserving UWSNs clustering algorithm based on type II fuzzy logic (T2FL). With the remaining energy of nodes, the number of neighboring nodes, and the communication distance as fuzzy inputs, the Cluster Head (CH) election score and communication range are calculated through T2FL to better balance the network energy consumption. And this paper proposes the neighborhood CH coexistence mechanism to reduce the number of nodes that fail to join clusters. The simulation results show that the algorithm can effectively reduce the variance of residual energy between nodes in the workflow and significantly prolong the working time under the maximum network coverage, indicating that the proposed algorithm has an excellent energy balance effect. © 2023 IEEE.

With the development of 5G technology, 5G cellular networks have covered most cities in china. Positioning based on 5G opportunity signals has been widely focused on by researchers. In this paper, the positioning capabilities of 5G outdoor macro base stations downlink signals have been analyzed first. Then a novel phase-locked loop based on the ESPRIT algorithm is proposed to improve the accuracy of the tracking stage. Finally, to verify the ranging accuracy of the designed receiver, we conduct field tests of outdoor 5G macro base stations in a real city environment based on a software-defined radio platform. The test results indicate that in a dynamic pedestrian movement environment, the average RMSE of distance measurements obtained by continuously receiving 5G signals over two different paths is 5.37 meters. © 2023 IEEE.
