This paper presents a novel method for using full duplex (FD) communication across shared channels in cellular vehicle-to-everything (C-V2X) networks. Three modes A, B and C have been defined for communication in V2X networks where Mode C for FD communication has been introduced for the first time. We have derived mathematical model for success probability of FD for C-V2X network and formulated expressions for area spectral efficiency (ASE). Dual connectivity (DC) for simultaneous link of receiving vehicle with nearest transmitting vehicle and base station (BS) has also been analyzed for the first time for HD and FD in C-V2X network. Analytical and Monte Carlo simulations results have shown that utilization of FD in C-V2X network provides comparable success probability as compared to HD with improvement in ASE. Success probability of FD remains close to HD in terms of signal to interference noise ratio (SINR) in the range from -40 dBW to 60 dBW. Importance of achieving perfect self-interference cancellation (SIC) for different values of self-interference (SI) in FD network has also been evaluated. FD in C-V2X network has shown to significantly improve ASE with gain of 2.55 dB over Direct Short Range Communication (DSRC) and 2 dB over HD in C-V2X network under specific conditions. No degradation in ASE was observed in case of DC for HD and FD. ASE for FD has shown improvement as compared to HD for DSRC and C-V2X networks when evaluated against density of vehicles, BSs and roads.
本文介绍了一种在蜂窝式车对物(C-V2X)网络的共享信道上使用全双工(FD)通信的新方法。V2X 网络中的通信定义了三种模式 A、B 和 C,其中首次引入了用于 FD 通信的模式 C。我们推导出了 C-V2X 网络 FD 成功概率的数学模型,并制定了区域频谱效率 (ASE) 的表达式。我们还首次分析了 C-V2X 网络中高清和远距离传输的双连接(DC),即接收车与最近的发射车和基站(BS)同时链接。分析和蒙特卡罗模拟结果表明,在 C-V2X 网络中使用 FD 与 HD 相比,成功概率相当,但 ASE 有所提高。在 -40 dBW 至 60 dBW 范围内,就信号干扰噪声比 (SINR) 而言,FD 的成功概率与 HD 接近。此外,还评估了在 FD 网络中针对不同的自干扰(SI)值实现完美自干扰消除(SIC)的重要性。在特定条件下,C-V2X 网络中的 FD 可显著改善 ASE,与直接短程通信 (DSRC) 相比增益为 2.55 dB,与 C-V2X 网络中的 HD 相比增益为 2 dB。在直流情况下,HD 和 FD 的 ASE 没有下降。在根据车辆、BS 和道路密度进行评估时,在 DSRC 和 C-V2X 网络中,与 HD 相比,FD 的 ASE 有所提高。

With the advancement of satellite and 5G communication technologies, vehicles can transmit and exchange data from anywhere in the world. It has resulted in the generation of massive spatial trajectories, particularly from the Automatic Identification System (AIS) for surface vehicles. The massive AIS data lead to high storage requirements and computing costs, as well as low data transmission efficiency. These challenges highlight the critical importance of vessel trajectory compression for surface vehicles. However, the complexity and diversity of vessel trajectories and behaviors make trajectory compression imperative and challenging in maritime applications. Therefore, trajectory compression has been one of the hot spots in research on trajectory data mining. The major purpose of this work is to provide a comprehensive reference source for beginners involved in vessel trajectory compression. The current trajectory compression methods could be broadly divided into two types, batch (offline) and online modes. The principles and pseudo-codes of these methods will be provided and discussed in detail. In addition, compressive experiments on several publicly available data sets have been implemented to evaluate the batch and online compression methods in terms of computation time, compression ratio, trajectory similarity, and trajectory length loss rate. Finally, we develop a flexible and open software, called AISCompress, for AIS-based batch and online vessel trajectory compression. The conclusions and associated future works are also given to inspire future applications in vessel trajectory compression.
随着卫星和 5G 通信技术的发展,车辆可以在世界任何地方传输和交换数据。这就产生了大量的空间轨迹,尤其是地面车辆的自动识别系统(AIS)。海量 AIS 数据导致存储要求高、计算成本高以及数据传输效率低。这些挑战凸显了水面车辆船只轨迹压缩的极端重要性。然而,船舶轨迹和行为的复杂性和多样性使得轨迹压缩在海事应用中变得势在必行且极具挑战性。因此,轨迹压缩一直是轨迹数据挖掘研究的热点之一。这项工作的主要目的是为从事船舶轨迹压缩的初学者提供全面的参考资料。目前的轨迹压缩方法大致可分为批量(离线)和在线两种模式。本文将详细介绍和讨论这些方法的原理和伪代码。此外,我们还在几个公开数据集上进行了压缩实验,从计算时间、压缩率、轨迹相似度和轨迹长度损失率等方面对批量和在线压缩方法进行了评估。最后,我们开发了一个灵活开放的软件,名为 AISCompress,用于基于 AIS 的批量和在线船只轨迹压缩。我们还给出了结论和相关的未来工作,以启发未来在船舶轨迹压缩方面的应用。

This study realizes firmware-agnostic line-of-sight (LOS) identification to extend the range of WiFi-sensing applications. We developed a beamforming feedback (BFF)-based LOS identification algorithm. BFF frames are transmitted for multiple-input multiple-output (MIMO) communications. They can be obtained by capturing frames without custom firmware or specific chipsets and contain a beamforming feedback matrix (BFM) and subcarrier-averaged stream gain (SSG). These provide partial channel state information (CSI), and there are two major calculation steps involved from the CSI to the BFF: unquantized BFF (UQBFF) calculation and quantization. Focusing on the relationship between singular value decomposition and principal component analysis, we numerically demonstrated that the first column vectors of the BFM reflect the LOS/NLOS conditions. Therefore, the proposed BFF-based method extracts features from the first-column vectors of the BFM. In addition, SSGs were leveraged to improve the accuracy. To demonstrate the feasibility of the proposed method, we conducted experiments using commodity off-the-shelf devices compliant with the IEEE 802.11ac standard. In the experimental evaluation, the proposed BFF-based method achieved an identification accuracy of 75.0%, whereas the CSI-based method achieved an accuracy of 81.2%. Accuracy comparisons revealed that the accuracy degradation of the BFF-based identification from the CSI-based identification was primarily caused by UQBFF calculations rather than quantization.
本研究实现了与固件无关的视线(LOS)识别,以扩大 WiFi 传感应用的范围。我们开发了一种基于波束成形反馈(BFF)的 LOS 识别算法。BFF 帧是为多输入多输出(MIMO)通信而传输的。它们可以通过捕获帧获得,无需定制固件或特定芯片组,并包含波束成形反馈矩阵(BFM)和子载波平均流增益(SSG)。这些信息提供了部分信道状态信息(CSI),从 CSI 到 BFF 涉及两个主要计算步骤:未量化 BFF(UQBFF)计算和量化。针对奇异值分解和主成分分析之间的关系,我们用数值方法证明了 BFM 的第一列向量反映了 LOS/NLOS 条件。因此,所提出的基于 BFF 的方法可从 BFM 的第一列向量中提取特征。此外,还利用了 SSG 来提高精确度。为了证明所提方法的可行性,我们使用符合 IEEE 802.11ac 标准的现成商品设备进行了实验。在实验评估中,所提出的基于 BFF 的方法达到了 75.0% 的识别准确率,而基于 CSI 的方法达到了 81.2% 的准确率。准确度比较显示,与基于 CSI 的识别方法相比,基于 BFF 的识别方法的准确度下降主要是由 UQBFF 计算而非量化造成的。

V2X (Vehicle-to-everything) communication relies on short messages for short-range transmissions over a fading wireless channel, yet requires high reliability and low latency. Hard-decision decoding sacrifices the preservation of diversity order, leading to pronounced performance degradation in fading channels. By contrast, soft-decision decoding retains diversity order, albeit at the cost of increased computational complexity. We introduce a novel enhanced hard-decision decoder termed as the Diversity Flip decoder (DFD) designed for preserving the diversity order. Moreover, it exhibits ‘universal’ applicability to all linear block codes. For a $mathscr {C}(n,k)$ code having a minimum distance ${d_{min }}$, the proposed decoder incurs a worst-case complexity order of $2^{({d_{min }}-1)}-1$. Notably, for codes having low ${d_{min }}$, this complexity represents a significant reduction compared to the popular soft and hard decision decoding algorithms. Due to its capability of maintaining diversity at a low complexity, it is eminently suitable for applications such as V2X (Vehicle-to-everything), IoT (Internet of Things), mMTC (Massive Machine type Communications), URLLC (Ultra-Reliable Low Latency Communications) and WBAN (Wireless Body Area Networks) for efficient decoding with favorable performance characteristics. The simulation results provided for various known codes and decoding algorithms validate the performance versus complexity benefits of the proposed decoder.
V2X(车对万物)通信依靠短信息在衰减的无线信道上进行短距离传输,但要求高可靠性和低延迟。硬决策解码牺牲了分集顺序的保持,导致在衰减信道中性能明显下降。相比之下,软决策解码保留了分集顺序,但代价是增加了计算复杂度。我们引入了一种新的增强型硬判决解码器,称为分集翻转解码器(Diversity Flip decoder,DFD),旨在保留分集顺序。此外,它还表现出对所有线性块编码的 "普遍 "适用性。对于具有最小距离 ${d_{min }}$ 的 $mathscr {C}(n,k)$ 代码,所提出的解码器在最坏情况下的复杂度为 2^{({d_{min }}-1)}-1$ 。值得注意的是,对于具有较低{d_{min }}$的编码来说,与流行的软决策和硬决策解码算法相比,这一复杂度显著降低。由于它能以较低的复杂度保持多样性,因此非常适合 V2X(车对万物)、IoT(物联网)、mMTC(大规模机器类型通信)、URLLC(超可靠低延迟通信)和 WBAN(无线体域网)等应用,可实现具有良好性能特征的高效解码。针对各种已知编码和解码算法提供的仿真结果验证了拟议解码器的性能与复杂性优势。

Millimeter-wave (MmWave) channel characteristics are quite different from sub-6 GHz frequency bands. The major differences include higher path loss and sparser multipath components (MPCs), resulting in more significant time-varying characteristics in mmWave channels. It is difficult to characterize the time-varying characteristics of mmWave channels through statistical models, e.g. slope-intercept models for path loss and lognormal models for delay spread and angular spread. Therefore, highly accurate channel modeling and prediction are necessary for deployment of mmWave communication systems. In this paper, a mmWave channel parameter prediction method using deep learning and environment point cloud is proposed. The parameters predicted include path loss, root-mean-square (RMS) delay spread, angular spread and Rician $K$ factor. First, we introduce a novel measurement campaign for indoor mmWave channel at 60 GHz, where a light detection and ranging (LiDAR) sensor and panoramic camera were co-located with a channel sounder and then time-synchronized point clouds and images were captured to describe environmental information. Furthermore, a fusion method between the point clouds and images is proposed based on geometric relationship between the LiDAR and camera, to compress the size of the data collected. Second, based on a classic point cloud classification model (PointNet), we propose a novel regression PointNet model applied to channel parameter prediction. To overcome generalization problem of model under limited measurements, an area-by-area training and testing method is proposed. Third, we evaluate the proposed prediction model and training method, by comparing prediction results with measured ground truth. To provide insights on what training inputs are best, we demonstrate the impacts of different combinations of input information on prediction accuracy. Last, the deployment and implementation method of the proposed model is recommended to the readers.
毫米波(MmmWave)信道特性与 6 GHz 以下频段有很大不同。主要差异包括更高的路径损耗和更稀疏的多径分量(MPC),从而导致毫米波信道具有更显著的时变特性。很难通过统计模型来描述毫米波信道的时变特性,例如路径损耗的斜率-截距模型以及延迟传播和角度传播的对数正态模型。因此,高精度的信道建模和预测对于毫米波通信系统的部署十分必要。本文提出了一种利用深度学习和环境点云的毫米波信道参数预测方法。预测的参数包括路径损耗、均方根(RMS)延迟传播、角传播和里克里亚系数(Rician $K$ factor)。首先,我们介绍了一种新颖的 60 GHz 室内毫米波信道测量活动,将光探测与测距(LiDAR)传感器和全景相机与信道测深仪共定位,然后捕获时间同步的点云和图像来描述环境信息。此外,基于激光雷达和相机之间的几何关系,提出了点云和图像的融合方法,以压缩采集数据的大小。其次,在经典的点云分类模型(PointNet)基础上,我们提出了一种新颖的回归 PointNet 模型,并将其应用于通道参数预测。为了克服模型在有限测量条件下的泛化问题,我们提出了一种分区域训练和测试的方法。第三,我们通过比较预测结果和测量的地面实况来评估所提出的预测模型和训练方法。为了深入了解什么是最佳的训练输入,我们展示了不同输入信息组合对预测精度的影响。最后,向读者推荐了建议模型的部署和实施方法。

Electric vehicle (EV) adoption has been increasing rapidly, posing new challenges for integrating EV charging infrastructure with the existing electrical grid. Uncoordinated charging of EVs can cause transformers to overload, leading to instability and unreliability in the grid. This article introduces two smart charging coordinators for EV charging pools designed to manage EV charging while considering transformer power limits. The first strategy aims to minimize operational costs, while the second maximizes the charger flexibility. Both coordinators account for uncertainties in EV arrival time and state of charge, as well as inflexible demands on transformers. The strategies are evaluated and compared using grid-aware and grid-unaware methods regarding transformer power limits. Real-world datasets are utilized to assess the performance of the proposed strategies through simulation studies across three scenarios: single charging station behavior, average parking lot occupancy, and worst-case occupancy scenarios. Comparative analysis against uncoordinated and coordinated strategies from the literature reveals that the flexibility maximization strategy provides the most uniform response, effectively mitigating transformer overload events by optimizing charging power and scheduling flexibility. The study underscores the importance of accurate, innovative charging strategies for seamless EV integration and emphasizes the necessity of coordinated charging pools for reliable EV charging operations.
电动汽车(EV)的采用率一直在快速增长,这给电动汽车充电基础设施与现有电网的整合带来了新的挑战。不协调的电动汽车充电会导致变压器过载,从而导致电网的不稳定和不可靠。本文介绍了两种用于电动汽车充电池的智能充电协调器,旨在管理电动汽车充电,同时考虑变压器功率限制。第一种策略旨在最大限度地降低运营成本,而第二种策略则最大限度地提高充电器的灵活性。两种协调器都考虑了电动汽车到达时间和充电状态的不确定性,以及对变压器的不灵活需求。在变压器功率限制方面,采用电网感知和电网非感知方法对这两种策略进行了评估和比较。利用真实世界的数据集,通过对三种场景的模拟研究来评估所提出策略的性能:单一充电站行为、停车场平均占用率和最坏情况占用率场景。与文献中的非协调策略和协调策略进行比较分析后发现,灵活性最大化策略提供了最统一的响应,通过优化充电功率和调度灵活性,有效缓解了变压器过载事件。这项研究强调了准确、创新的充电策略对电动汽车无缝集成的重要性,并强调了协调充电池对可靠的电动汽车充电运营的必要性。

Recent technological advancements in space, air, and ground components have made possible a new network paradigm called “space-air-ground integrated network” (SAGIN). Unmanned aerial vehicles (UAVs) play a key role in SAGINs. However, due to UAVs' high dynamics and complexity, real-world deployment of a SAGIN becomes a significant barrier to realizing such SAGINs. UAVs are expected to meet key performance requirements with limited maneuverability and resources with space and terrestrial components. Therefore, employing UAVs in various usage scenarios requires well-designed planning in algorithmic approaches. This paper provides an essential review and analysis of recent learning algorithms in a UAV-assisted SAGIN. We consider possible reward functions and discuss the state-of-the-art algorithms for optimizing the reward functions, including Q-learning, deep Q-learning, multi-armed bandit, particle swarm optimization, and satisfaction-based learning algorithms. Unlike other survey papers, we focus on the methodological perspective of the optimization problem, applicable to various missions on a SAGIN. We consider real-world configurations and the 2-dimensional (2D) and 3-dimensional (3D) UAV trajectories to reflect deployment cases. Our simulations suggest the 3D satisfaction-based learning algorithm outperforms other approaches in most cases. With open challenges discussed at the end, we aim to provide design and deployment guidelines for UAV-assisted SAGINs.
最近在空间、空中和地面组件方面取得的技术进步使一种名为 "空间-空中-地面综合网络"(SAGIN)的新网络范例成为可能。无人飞行器(UAV)在 SAGIN 中发挥着关键作用。然而,由于无人飞行器的高动态性和复杂性,SAGIN 的实际部署成为实现这种 SAGIN 的重大障碍。无人机需要在有限的机动性和资源条件下,利用空间和地面组件满足关键性能要求。因此,在各种使用场景中使用无人机需要精心设计的算法规划。本文对无人机辅助 SAGIN 的最新学习算法进行了基本回顾和分析。我们考虑了可能的奖励函数,并讨论了最先进的奖励函数优化算法,包括 Q-learning 算法、深度 Q-learning 算法、多臂匪徒算法、粒子群优化算法和基于满意度的学习算法。与其他调查报告不同的是,我们侧重于优化问题的方法论角度,适用于 SAGIN 上的各种任务。我们考虑了真实世界的配置以及二维(2D)和三维(3D)无人机轨迹,以反映部署情况。我们的模拟结果表明,在大多数情况下,基于三维满意度的学习算法优于其他方法。最后,我们讨论了有待解决的挑战,旨在为无人机辅助 SAGINs 的设计和部署提供指导。

In the automotive industry, the accurate estimation of wheel displacements is crucial for optimizing vehicle suspension systems. Traditional model-based approaches often face challenges in accurately predicting these displacements due to the complex dynamics of the road-vehicle interaction. To address this limitation, this study, conducted in the frame of the OWHEEL project, proposes the integration of a multi-output neural network capable of compensating for estimation errors inherent in model-based approaches, specifically those arising from road inputs. Leveraging only vertical acceleration measurements, the neural network operates in parallel with the model-based estimator, enhancing the overall accuracy of displacement estimation. Experimental validation using a sports vehicle demonstrates the efficacy of the proposed methodology, showcasing its ability to improve estimation accuracy beyond the capabilities of the model-based approach alone.
在汽车行业,车轮位移的精确估算对于优化车辆悬挂系统至关重要。由于道路与车辆相互作用的动态十分复杂,传统的基于模型的方法在准确预测这些位移方面往往面临挑战。为了解决这一局限性,本研究在 OWHEEL 项目框架内进行,提出集成一个多输出神经网络,该网络能够补偿基于模型的方法中固有的估计误差,特别是由道路输入引起的误差。神经网络仅利用垂直加速度测量值,与基于模型的估算器并行运行,从而提高了位移估算的整体准确性。使用跑车进行的实验验证证明了所提方法的有效性,展示了其提高估算精度的能力,超越了基于模型方法的单独能力。

The rapid progression of Cloud Computing (CC) technology has ushered in innovative ecosystem concepts such as Mobile Cloud Computing (MCC). In this context, the incorporation of Unmanned Aerial Vehicles (UAVs) into these cloud ecosystems has unlocked new avenues for use cases such as delivery services, disaster response, and surveillance. However, this integration presents challenges in resource management and service selection due to the unique constraints of drones and variations in service quality. This paper proposes a Game Theory-based UAV-cloud of Service Selection Architecture (GT-SSA) to address resource management and service selection challenges. By leveraging game theory in our proposal, GT-SSA optimizes decision-making for Client Drones and Provider Drones, enhancing service selection efficiency. GT-SSA proved its resilience to scalability concerns, as evidenced in Discovery Delay, Consumption Delay, End-to-End Delay, and Energy consumption. Moreover, when GT-SSA is compared with the Game Theory approach for Cloud Services in MEC- and UAV-enabled networks (GTCS), GT-SSA outperforms GTCS in terms of Successful Execution Rate, Average Execution Time, and Energy consumption. Our research also reveals that game theory surpasses fuzzy logic in terms of service selection efficiency.
云计算(CC)技术的快速发展带来了创新的生态系统概念,如移动云计算(MCC)。在此背景下,无人驾驶飞行器(UAV)融入这些云生态系统,为交付服务、灾难响应和监控等用例开辟了新的途径。然而,由于无人机的独特限制和服务质量的差异,这种整合给资源管理和服务选择带来了挑战。本文提出了基于博弈论的无人机云服务选择架构(GT-SSA),以应对资源管理和服务选择方面的挑战。通过利用我们建议中的博弈论,GT-SSA 优化了客户无人机和提供商无人机的决策,提高了服务选择效率。GT-SSA 在发现延迟、消耗延迟、端到端延迟和能耗方面证明了其对可扩展性问题的适应能力。此外,当将 GT-SSA 与 MEC 和无人机网络中云服务的博弈论方法(GTCS)进行比较时,GT-SSA 在成功执行率、平均执行时间和能耗方面均优于 GTCS。我们的研究还表明,博弈论在服务选择效率方面超过了模糊逻辑。
