边缘计算（EC）的出现是一种有希望的范式，可提供靠近数据源的多个计算和分析功能，为新型应用开辟了新的途径。但是，EC节点的计算能力有限，并期望确保任务执行期间高水平的QoS对创新管理方法施加了严格的要求。由于需要在EC节点运行期间保持最低QoS水平的动机，我们阐述了针对任务调度的分布式和智能的决策方法。我们的目标是增强EC节点的行为，使其能够确保高QoS水平。我们建议节点连续监视QoS级别，并系统地评估违反它们以主动决定某些任务以将其卸载到同行节点或云的概率。我们通过多种实验场景介绍，描述和评估所提出的方案，揭示其性能以及在EC等非常动态的环境中服务处理请求时所设想的监视机制的好处。

In recent years, the exponential proliferation of smart devices with their intelligent applications poses severe challenges on conventional cellular networks. Such challenges can be potentially overcome by integrating communication, computing, caching, and control (i4C) technologies. In this survey, we first give a snapshot of different aspects of the i4C, comprising background, motivation, leading technological enablers, potential applications, and use cases. Next, we describe different models of communication, computing, caching, and control (4C) to lay the foundation of the integration approach. We review current state-of-the-art research efforts related to the i4C, focusing on recent trends of both conventional and artificial intelligence (AI)-based integration approaches. We also highlight the need for intelligence in resources integration. Then, we discuss integration of sensing and communication (ISAC) and classify the integration approaches into various classes. Finally, we propose open challenges and present future research directions for beyond 5G networks, such as 6G.

Video, as a key driver in the global explosion of digital information, can create tremendous benefits for human society. Governments and enterprises are deploying innumerable cameras for a variety of applications, e.g., law enforcement, emergency management, traffic control, and security surveillance, all facilitated by video analytics (VA). This trend is spurred by the rapid advancement of deep learning (DL), which enables more precise models for object classification, detection, and tracking. Meanwhile, with the proliferation of Internet-connected devices, massive amounts of data are generated daily, overwhelming the cloud. Edge computing, an emerging paradigm that moves workloads and services from the network core to the network edge, has been widely recognized as a promising solution. The resulting new intersection, edge video analytics (EVA), begins to attract widespread attention. Nevertheless, only a few loosely-related surveys exist on this topic. A dedicated venue for collecting and summarizing the latest advances of EVA is highly desired by the community. Besides, the basic concepts of EVA (e.g., definition, architectures, etc.) are ambiguous and neglected by these surveys due to the rapid development of this domain. A thorough clarification is needed to facilitate a consensus on these concepts. To fill in these gaps, we conduct a comprehensive survey of the recent efforts on EVA. In this paper, we first review the fundamentals of edge computing, followed by an overview of VA. The EVA system and its enabling techniques are discussed next. In addition, we introduce prevalent frameworks and datasets to aid future researchers in the development of EVA systems. Finally, we discuss existing challenges and foresee future research directions. We believe this survey will help readers comprehend the relationship between VA and edge computing, and spark new ideas on EVA.

In recent years, mobile devices are equipped with increasingly advanced sensing and computing capabilities. Coupled with advancements in Deep Learning (DL), this opens up countless possibilities for meaningful applications, e.g., for medical purposes and in vehicular networks. Traditional cloudbased Machine Learning (ML) approaches require the data to be centralized in a cloud server or data center. However, this results in critical issues related to unacceptable latency and communication inefficiency. To this end, Mobile Edge Computing (MEC) has been proposed to bring intelligence closer to the edge, where data is produced. However, conventional enabling technologies for ML at mobile edge networks still require personal data to be shared with external parties, e.g., edge servers. Recently, in light of increasingly stringent data privacy legislations and growing privacy concerns, the concept of Federated Learning (FL) has been introduced. In FL, end devices use their local data to train an ML model required by the server. The end devices then send the model updates rather than raw data to the server for aggregation. FL can serve as an enabling technology in mobile edge networks since it enables the collaborative training of an ML model and also enables DL for mobile edge network optimization. However, in a large-scale and complex mobile edge network, heterogeneous devices with varying constraints are involved. This raises challenges of communication costs, resource allocation, and privacy and security in the implementation of FL at scale. In this survey, we begin with an introduction to the background and fundamentals of FL. Then, we highlight the aforementioned challenges of FL implementation and review existing solutions. Furthermore, we present the applications of FL for mobile edge network optimization. Finally, we discuss the important challenges and future research directions in FL.

未来的互联网涉及几种新兴技术，例如5G和5G网络，车辆网络，无人机（UAV）网络和物联网（IOT）。此外，未来的互联网变得异质并分散了许多相关网络实体。每个实体可能需要做出本地决定，以在动态和不确定的网络环境下改善网络性能。最近使用标准学习算法，例如单药强化学习（RL）或深入强化学习（DRL），以使每个网络实体作为代理人通过与未知环境进行互动来自适应地学习最佳决策策略。但是，这种算法未能对网络实体之间的合作或竞争进行建模，而只是将其他实体视为可能导致非平稳性问题的环境的一部分。多机构增强学习（MARL）允许每个网络实体不仅观察环境，还可以观察其他实体的政策来学习其最佳政策。结果，MAL可以显着提高网络实体的学习效率，并且最近已用于解决新兴网络中的各种问题。在本文中，我们因此回顾了MAL在新兴网络中的应用。特别是，我们提供了MARL的教程，以及对MARL在下一代互联网中的应用进行全面调查。特别是，我们首先介绍单代机Agent RL和MARL。然后，我们回顾了MAL在未来互联网中解决新兴问题的许多应用程序。这些问题包括网络访问，传输电源控制，计算卸载，内容缓存，数据包路由，无人机网络的轨迹设计以及网络安全问题。

随着人工智能（AI）的积极发展，基于深神经网络（DNN）的智能应用会改变人们的生活方式和生产效率。但是，从网络边缘生成的大量计算和数据成为主要的瓶颈，传统的基于云的计算模式无法满足实时处理任务的要求。为了解决上述问题，通过将AI模型训练和推理功能嵌入网络边缘，Edge Intelligence（EI）成为AI领域的尖端方向。此外，云，边缘和终端设备之间的协作DNN推断提供了一种有希望的方法来增强EI。然而，目前，以EI为导向的协作DNN推断仍处于早期阶段，缺乏对现有研究工作的系统分类和讨论。因此，我们已经对有关以EI为导向的协作DNN推断的最新研究进行了全面调查。在本文中，我们首先回顾了EI的背景和动机。然后，我们为EI分类了四个典型的DNN推理范例，并分析其特征和关键技术。最后，我们总结了协作DNN推断的当前挑战，讨论未来的发展趋势并提供未来的研究方向。

使用人工智能（AI）赋予无线网络中数据量的前所未有的数据量激增，为提供无处不在的数据驱动智能服务而开辟了新的视野。通过集中收集数据集和培训模型来实现传统的云彩中心学习（ML）基础的服务。然而，这种传统的训练技术包括两个挑战：（i）由于数据通信增加而导致的高通信和能源成本，（ii）通过允许不受信任的各方利用这些信息来威胁数据隐私。最近，鉴于这些限制，一种新兴的新兴技术，包括联合学习（FL），以使ML带到无线网络的边缘。通过以分布式方式培训全局模型，可以通过FL Server策划的全局模型来提取数据孤岛的好处。 FL利用分散的数据集和参与客户的计算资源，在不影响数据隐私的情况下开发广义ML模型。在本文中，我们介绍了对FL的基本面和能够实现技术的全面调查。此外，提出了一个广泛的研究，详细说明了无线网络中的流体的各种应用，并突出了他们的挑战和局限性。进一步探索了FL的疗效，其新兴的前瞻性超出了第五代（B5G）和第六代（6G）通信系统。本调查的目的是在关键的无线技术中概述了流动的技术，这些技术将作为建立对该主题的坚定了解的基础。最后，我们向未来的研究方向提供前进的道路。

随着数据生成越来越多地在没有连接连接的设备上进行，因此与机器学习（ML）相关的流量将在无线网络中无处不在。许多研究表明，传统的无线协议高效或不可持续以支持ML，这创造了对新的无线通信方法的需求。在这项调查中，我们对最先进的无线方法进行了详尽的审查，这些方法是专门设计用于支持分布式数据集的ML服务的。当前，文献中有两个明确的主题，模拟的无线计算和针对ML优化的数字无线电资源管理。这项调查对这些方法进行了全面的介绍，回顾了最重要的作品，突出了开放问题并讨论了应用程序方案。

如今，混合云平台作为打算实施私人和公共云应用组合的组织的有吸引力的解决方案，以满足其盈利能力。但是，这只能通过在加速执行过程时利用可用资源来实现。因此，部署新应用程序需要将其中一些流程致力于私有云解决方案，同时将其他过程分配给公共云。在此上下文中，设置本工作以帮助最小化相关成本，并在最小的执行时间内为最佳服务放置解决方案提供有效的选择。已经应用了几种进化算法来解决服务放置问题，并且在处理复杂的解决方案空间以提供最佳放置并经常产生短的执行时间。除了在处理服务放置问题方面发明细缺乏鲁棒性之外，还发现标准BPSO算法显示出显着的缺点，即容易捕获到本地Optima之外。因此，为了克服与标准BPSO相关的关键缺点，提出了增强的二进制粒子群优化（E-BPSO）算法，由粒子位置更新方程的修改组成，最初从连续PSO激发。我们所提出的E-BPSO算法显示在成本和执行时间方面以实际基准测试优越最先进的方法。

With the increasing growth of information through smart devices, increasing the quality level of human life requires various computational paradigms presentation including the Internet of Things, fog, and cloud. Between these three paradigms, the cloud computing paradigm as an emerging technology adds cloud layer services to the edge of the network so that resource allocation operations occur close to the end-user to reduce resource processing time and network traffic overhead. Hence, the resource allocation problem for its providers in terms of presenting a suitable platform, by using computational paradigms is considered a challenge. In general, resource allocation approaches are divided into two methods, including auction-based methods(goal, increase profits for service providers-increase user satisfaction and usability) and optimization-based methods(energy, cost, network exploitation, Runtime, reduction of time delay). In this paper, according to the latest scientific achievements, a comprehensive literature study (CLS) on artificial intelligence methods based on resource allocation optimization without considering auction-based methods in various computing environments are provided such as cloud computing, Vehicular Fog Computing, wireless, IoT, vehicular networks, 5G networks, vehicular cloud architecture,machine-to-machine communication(M2M),Train-to-Train(T2T) communication network, Peer-to-Peer(P2P) network. Since deep learning methods based on artificial intelligence are used as the most important methods in resource allocation problems; Therefore, in this paper, resource allocation approaches based on deep learning are also used in the mentioned computational environments such as deep reinforcement learning, Q-learning technique, reinforcement learning, online learning, and also Classical learning methods such as Bayesian learning, Cummins clustering, Markov decision process.

智能物联网环境（iiote）由可以协作执行半自动的IOT应用的异构装置，其示例包括高度自动化的制造单元或自主交互收获机器。能量效率是这种边缘环境中的关键，因为它们通常基于由无线和电池运行设备组成的基础设施，例如电子拖拉机，无人机，自动引导车辆（AGV）S和机器人。总能源消耗从多种技术技术汲取贡献，使得能够实现边缘计算和通信，分布式学习以及分布式分区和智能合同。本文提供了本技术的最先进的概述，并说明了它们的功能和性能，特别关注资源，延迟，隐私和能源消耗之间的权衡。最后，本文提供了一种在节能IIOTE和路线图中集成这些能力技术的愿景，以解决开放的研究挑战

事件处理是动态和响应互联网（物联网）的基石。该领域的最近方法基于代表性状态转移（REST）原则，其允许将事件处理任务放置在遵循相同原理的任何设备上。但是，任务应在边缘设备之间正确分布，以确保公平资源利用率和保证无缝执行。本文调查了深入学习的使用，以公平分配任务。提出了一种基于关注的神经网络模型，在不同场景下产生有效的负载平衡解决方案。所提出的模型基于变压器和指针网络架构，并通过Advantage演员批评批评学习算法训练。该模型旨在缩放到事件处理任务的数量和边缘设备的数量，不需要重新调整甚至再刷新。广泛的实验结果表明，拟议的模型在许多关键绩效指标中优于传统的启发式。通用设计和所获得的结果表明，所提出的模型可能适用于几个其他负载平衡问题变化，这使得该提案是由于其可扩展性和效率而在现实世界场景中使用的有吸引力的选择。

联邦学习（FL）变得流行，并在训练大型机器学习（ML）模型的情况下表现出很大的潜力，而不会使所有者的原始数据曝光。在FL中，数据所有者可以根据其本地数据培训ML模型，并且仅将模型更新发送到模型更新，而不是原始数据到模型所有者进行聚合。为了提高模型准确性和培训完成时间的学习绩效，招募足够的参与者至关重要。同时，数据所有者是理性的，可能不愿意由于资源消耗而参与协作学习过程。为了解决这些问题，最近有各种作品旨在激励数据业主贡献其资源。在本文中，我们为文献中提出的经济和游戏理论方法提供了全面的审查，以设计刺激数据业主参加流程培训过程的各种计划。特别是，我们首先在激励机制设计中常用的佛罗里达州的基础和背景，经济理论。然后，我们审查博弈理论和经济方法应用于FL的激励机制的应用。最后，我们突出了一些开放的问题和未来关于FL激励机制设计的研究方向。

互联网连接系统的指数增长产生了许多挑战，例如频谱短缺问题，需要有效的频谱共享（SS）解决方案。复杂和动态的SS系统可以接触不同的潜在安全性和隐私问题，需要保护机制是自适应，可靠和可扩展的。基于机器学习（ML）的方法经常提议解决这些问题。在本文中，我们对最近的基于ML的SS方法，最关键的安全问题和相应的防御机制提供了全面的调查。特别是，我们详细说明了用于提高SS通信系统的性能的最先进的方法，包括基于ML基于ML的基于的数据库辅助SS网络，ML基于基于的数据库辅助SS网络，包括基于ML的数据库辅助的SS网络，基于ML的LTE-U网络，基于ML的环境反向散射网络和其他基于ML的SS解决方案。我们还从物理层和基于ML算法的相应防御策略的安全问题，包括主要用户仿真（PUE）攻击，频谱感测数据伪造（SSDF）攻击，干扰攻击，窃听攻击和隐私问题。最后，还给出了对ML基于ML的开放挑战的广泛讨论。这种全面的审查旨在为探索新出现的ML的潜力提供越来越复杂的SS及其安全问题，提供基础和促进未来的研究。

Explainable Artificial Intelligence (XAI) is transforming the field of Artificial Intelligence (AI) by enhancing the trust of end-users in machines. As the number of connected devices keeps on growing, the Internet of Things (IoT) market needs to be trustworthy for the end-users. However, existing literature still lacks a systematic and comprehensive survey work on the use of XAI for IoT. To bridge this lacking, in this paper, we address the XAI frameworks with a focus on their characteristics and support for IoT. We illustrate the widely-used XAI services for IoT applications, such as security enhancement, Internet of Medical Things (IoMT), Industrial IoT (IIoT), and Internet of City Things (IoCT). We also suggest the implementation choice of XAI models over IoT systems in these applications with appropriate examples and summarize the key inferences for future works. Moreover, we present the cutting-edge development in edge XAI structures and the support of sixth-generation (6G) communication services for IoT applications, along with key inferences. In a nutshell, this paper constitutes the first holistic compilation on the development of XAI-based frameworks tailored for the demands of future IoT use cases.

In this tutorial paper, we look into the evolution and prospect of network architecture and propose a novel conceptual architecture for the 6th generation (6G) networks. The proposed architecture has two key elements, i.e., holistic network virtualization and pervasive artificial intelligence (AI). The holistic network virtualization consists of network slicing and digital twin, from the aspects of service provision and service demand, respectively, to incorporate service-centric and user-centric networking. The pervasive network intelligence integrates AI into future networks from the perspectives of networking for AI and AI for networking, respectively. Building on holistic network virtualization and pervasive network intelligence, the proposed architecture can facilitate three types of interplay, i.e., the interplay between digital twin and network slicing paradigms, between model-driven and data-driven methods for network management, and between virtualization and AI, to maximize the flexibility, scalability, adaptivity, and intelligence for 6G networks. We also identify challenges and open issues related to the proposed architecture. By providing our vision, we aim to inspire further discussions and developments on the potential architecture of 6G.

In recent years, deep learning (DL) models have demonstrated remarkable achievements on non-trivial tasks such as speech recognition and natural language understanding. One of the significant contributors to its success is the proliferation of end devices that acted as a catalyst to provide data for data-hungry DL models. However, computing DL training and inference is the main challenge. Usually, central cloud servers are used for the computation, but it opens up other significant challenges, such as high latency, increased communication costs, and privacy concerns. To mitigate these drawbacks, considerable efforts have been made to push the processing of DL models to edge servers. Moreover, the confluence point of DL and edge has given rise to edge intelligence (EI). This survey paper focuses primarily on the fifth level of EI, called all in-edge level, where DL training and inference (deployment) are performed solely by edge servers. All in-edge is suitable when the end devices have low computing resources, e.g., Internet-of-Things, and other requirements such as latency and communication cost are important in mission-critical applications, e.g., health care. Firstly, this paper presents all in-edge computing architectures, including centralized, decentralized, and distributed. Secondly, this paper presents enabling technologies, such as model parallelism and split learning, which facilitate DL training and deployment at edge servers. Thirdly, model adaptation techniques based on model compression and conditional computation are described because the standard cloud-based DL deployment cannot be directly applied to all in-edge due to its limited computational resources. Fourthly, this paper discusses eleven key performance metrics to evaluate the performance of DL at all in-edge efficiently. Finally, several open research challenges in the area of all in-edge are presented.

Unmanned aerial vehicle (UAV) swarms are considered as a promising technique for next-generation communication networks due to their flexibility, mobility, low cost, and the ability to collaboratively and autonomously provide services. Distributed learning (DL) enables UAV swarms to intelligently provide communication services, multi-directional remote surveillance, and target tracking. In this survey, we first introduce several popular DL algorithms such as federated learning (FL), multi-agent Reinforcement Learning (MARL), distributed inference, and split learning, and present a comprehensive overview of their applications for UAV swarms, such as trajectory design, power control, wireless resource allocation, user assignment, perception, and satellite communications. Then, we present several state-of-the-art applications of UAV swarms in wireless communication systems, such us reconfigurable intelligent surface (RIS), virtual reality (VR), semantic communications, and discuss the problems and challenges that DL-enabled UAV swarms can solve in these applications. Finally, we describe open problems of using DL in UAV swarms and future research directions of DL enabled UAV swarms. In summary, this survey provides a comprehensive survey of various DL applications for UAV swarms in extensive scenarios.

工作流程调度是一个并行和分布式计算（PDC）的长期研究，旨在有效地利用计算资源来满足用户的服务要求。最近提出的调度方法利用边缘计算平台的低响应时间来优化服务质量（QoS）。然而，由于计算异质性，移动设备的延迟以及工作负载资源要求的挥发性，因此由于计算异质性而挑战，在移动边缘云系统中的调度工作流程应用是具有挑战性的。为了克服这些困难，它是必不可少的，但同时具有挑战性，开发一种有效地模拟QoS目标的长视力优化方案。在这项工作中，我们提出了MCDS：Monte Carlo学习使用Deep代理模型来有效地安排移动边缘云计算系统中的工作流程应用。 MCD是一种基于人工智能（AI）的调度方法，它使用基于树的搜索策略和基于深度神经网络的代理模型来估计即时动作的长期QoS影响，以实现调度决策的鲁棒优化。物理和模拟边缘云试验台的实验表明，MCD在能耗，响应时间，SLA违规方面可以改善最先进的方法，违规和成本分别至少为6.13,4.56,45.09和30.71％。
