The x ad hoc network (xANET) termed as a family of ad hoc networks, including mobile ad hoc network (MANET), vehicular ad hoc network (VANET), flying ad hoc network (FANET) and satellite ad hoc network (SANET), has found a wide range of applications in providing ubiquitous wireless services. Despite its broad utility, the dynamic nature and lack of a centralized controller pose significant challenges to effective and flexible network management for xANET. Conventional network management protocols face challenges such as scalability, security vulnerabilities, configuration complexity, robustness, and performance resilience. Recent efforts have presented different approaches, focusing on policy-based network management (PBNM) and intent-driven network management (IDNM). However, there is no comprehensive survey to clarify their concepts and classifications. This paper presents a survey of the network management evolution for xANET, covering configuration-based, policy-based and the latest intent-driven approaches. We first introduce the characteristics and applications of xANET. Meanwhile, we investigate the network management concepts and challenges. Moreover, we survey the evolution of management protocols for xANET, including simple network management protocol (SNMP), PBNM, and IDNM. Then, we follow the detailed network management of xANET from configuration-based to policy-based and intent-driven approaches. Through comparative analysis, it is found that IDNM employs a more intelligent management protocol, demonstrating higher efficiency and flexibility in handling complex tasks and dynamic network management. This makes it better suited to addressing the challenges of xANET management. Finally, we summarize the remaining challenges and possible future research directions. © 2025 IEEE.

A novel leaky-wave antenna (LWA) with circular polarization (CP) and broadside radiation based on integrated substrate gap waveguide (ISGW) technology is proposed. A unique periodic structure, i.e. microstrip line with a periodic set of radiating stubs attached and series U-shape slot, is used to scan continuously from backward to forward and thus to form CP. The proposed LWA provides beam scanning from -29 to 12 over the frequency range of 21.5-27.5 GHz. Return loss less than -10 dB, and axial ratio less than 3 dB are achieved in 21 - 27.5 GHz (26.8%), and 21.16 - 26.05 GHz (20.7%), respectively. The average radiation efficiency is 87.8%. © 2021 IEEE.

Magnetic induction (MI) communication in nearfield scenarios has gained much attention in recent years. From the perspective of practical applications, nearfield magnetic induction (NFMI) communication limits its application in high rate demanded scenarios. In this paper, we propose the orthogonal frequency division multiplexing (OFDM) modulated orbital angular momentum (OAM)-based NFMI communication, which is called O2N communication, to increase the channel capacity where capacity limitation is a major bottleneck problem in magnetic communication systems. The O2N communication can adaptively optimize power allocation on subcarriers in association with OAM modes, significantly increasing the spectrum utilization of frequency-selective MI systems. Numerical results verify the transmission feasibility and capacity enhancement of O2N communication over multi-input multi-output (MIMO) OFDM-based magnetic communications in the near-field region. Moreover, the impact of misalignment on the O2N communication is also evaluated. High-capacity O2N communication based on the advantages of OAM and OFDM, can effectively support NFMI communication.

With wide applications of image editing tools, forged images have become a great public concern. Although existing methods for image forgery localization (IFL) could achieve fairly good results on several public datasets, most of them perform unsatisfactorily for cross-dataset evaluation and online social network applications. To tackle this issue, a novel coarse-to-fine framework using Diffusion probabilistic model for Image Forgery Localization (Diff-IFL) is proposed in this paper, which consists of a coarse localization module and a mask diffusion module. The coarse localization module employs a transformer-based architecture to represent the tampered images and generate coarse masks. While the mask diffusion module formulates IFL as a mask reconstruction task, it relies on the extracted forgery feature representations as the conditional prior to gradually recover the clean ground-truth mask from the noisy mask. Extensive experiments demonstrate that Diff-IFL outperforms other SOTA methods and exhibits superior robustness against social media forgery.

This article discusses a method for adjusting the radiation pattern of a base station antenna array when conducting radio communications in the millimeter wavelength range for mobile user devices. The article describes a technique for selecting a training sequence of beams that minimizes the Cramer-Rao lower bound when estimating the transmission direction. The proposed technique makes it possible to reduce the beam adjustment time for transmission by 16 times compared to the conventional protocol, which improves the quality of service for highly mobile users. © 2023 IEEE.

In this paper, the design of non-uniform antenna topology for 3D massive MIMO arrays in near-field communications is investigated. Specifically, the near-field spherical wavefront radiation characteristics are considered to accurately model the variations of signal phase across array elements. Subsequently, the closed-form expressions of the per-user signal-to-interference noise ratio (SINR) and achievable sum rate for a multi-user MIMO system with maximum-ratio transmission (MRT) precoding are derived. The focus is on the maximization of the achievable sum rate by optimizing the non-uniform 3D antenna array topology. Since the optimization problem exhibits highly nonlinear and nonconvex characteristics, an enhanced particle swarm optimization (EPSO) algorithm is proposed to effectively solve it. Numerical results demonstrate the superiority of the proposed non-uniform 3D array topology in near-field communications for enhancing the achievable sum rate.

This paper investigates intelligent reflecting surface (IRS) enabled non-line-of-sight (NLoS) wireless sensing, in which an IRS is deployed to assist an access point (AP) to sense a target in its NLoS region. It is assumed that the AP is equipped with multiple antennas and the IRS is equipped with a uniform linear array. The AP aims to estimate the target's direction-of-arrival (DoA) with respect to the IRS, based on the echo signals from the AP-IRS-target-IRS-AP link. Under this setup, we jointly design the transmit beamforming at the AP and the reflective beamforming at the IRS to minimize the CramérRao lower bound (CRLB) on estimation error. Towards this end, we first obtain the CRLB expression for estimating the DoA in closed form. Next, we optimize the joint beamforming design to minimize the CRLB, via alternating optimization, semi-definite relaxation, and successive convex approximation. Numerical results show that the proposed design based on CRLB minimization achieves improved sensing performance in terms of mean squared error, as compared to the traditional schemes with signal-to-noise ratio maximization and separate beamforming. © 2022 IEEE.

Large-vocabulary object detectors (LVDs) aim to detect objects of many categories, which learn super objectness features and can locate objects accurately while applied to various downstream data. However, LVDs often struggle in recognizing the located objects due to domain discrepancy in data distribution and object vocabulary. At the other end, recent vision-language foundation models such as CLIP demonstrate superior open-vocabulary recognition capability. This paper presents KGD, a Knowledge Graph Distillation technique that exploits the implicit knowledge graphs (KG) in CLIP for effectively adapting LVDs to various downstream domains. KGD consists of two consecutive stages: 1) KG extraction that employs CLIP to encode downstream domain data as nodes and their feature distances as edges, constructing KG that inherits the rich semantic relations in CLIP explicitly; and 2) KG encapsulation that transfers the extracted KG into LVDs to enable accurate cross-domain object classification. In addition, KGD can extract both visual and textual KG independently, providing complementary vision and language knowledge for object localization and object classification in detection tasks over various downstream domains. Experiments over multiple widely adopted detection benchmarks show that KGD outperforms the state-of-the-art consistently by large margins.
