Special Issue on Smart Green Applications: QoS and Security-Aware Solutions in Collaborative Wireless Networks (VSI-cwn)
Submission Date: 2020-08-15

In recent years, we have witnessed increasing interest in so-called green themes. In particular, most of this is aiming to search for concrete and efficient energy-aware approaches for new issues that have emerged as a result of the explosive growth of wireless scenarios. Smart solutions for reducing power consumption in wireless protocols has motivated us to develop and integrate new technologies and methods for intelligent ambient applications. The goal is to rapidly adapt and respond to existing changes in users’ (or environments’) demands for high-quality services. In fact, smart green application solutions are always deployed at core areas to meet or establish a good compromise between deadlines and Quality of Service (QoS)-aware requirements. The most challenging issue is that systems need real-time communication support to achieve strict latency requirements or deadlines. For instance, critical events in smart cities, smart home, and smart factories have proposed promising visions which are calling for industrial productions with rapid responses to demands. On the other hand, smart green application solutions can be vulnerable to various security threats and attacks if they are not secured. Consequently, it is necessary to study security aspects of those applications. Advanced technologies and approaches play important roles in the development of innovative solutions and/or optimization methods to achieve QoS and security-aware requirements. They also enable higher levels of adaptability and flexibility in collaborative wireless networks. Topics: This special section solicits high-quality unpublished work on recent advances in smart green applications which take into account QoS and security requirements in collaborative wireless networks. The main topics of interest include: ● Applications for smart space (city, home, industry, ...) ● Green communication architectures ● Smart green protocol designs ● Smart industrial IoT applications ● Sustainable design and solutions for green IoT ● System on-chip and network on-chip architectures ● Automation systems for real-time networks ● Resource-constrainedIoT devices optimizations ● Test-bed, prototype, and practical systems for green communication ● Security requirements and models in smart green applications ● Authentication and key management in smart green applications ● Security protocol and formal analysis in smart green applications

Special Issue on Autonomous computing and Its applications for self organizing networks (VSI-acson)
Submission Date: 2020-08-30

Autonomic computing is a self-managing computing model named after, and patterned on, the human body's autonomic nervous system. An autonomic computing system would control the functioning of computer applications and systems without input from the user, in the same way that the autonomic nervous system regulates body systems without conscious input from the individual. The goal of autonomic computing is to create systems that run themselves, capable of high-level functioning while keeping the system's complexity invisible to the user. The need for such autonomic system and application management is becoming critical as computing infrastructures become increasingly heterogeneous, integrating different classes of resources from high-end HPC systems to commodity clusters and clouds. Clouds are complex, large-scale, and heterogeneous distributed systems, management of whose resources is a challenging task. They need automated and integrated intelligent strategies for provisioning of resources to offer services that are secure, reliable, and cost-efficient. Hence, effective management of services becomes fundamental in software platforms that constitute the fabric of computing Clouds. Topics: Suggested topics include: Dependable Large Scale Distributed Systems (Cloud, Grid, P2P, Virtualization) for self organizing networks Autonomic Computing (Architectures and Systems, Theory and Models) for self organizing networks Autonomic computing and proactive computing for self organizing networks Self-optimizing software systems for computer networks Self-stabilization and dynamic stability criteria and mechanisms for self organizing networks Tools, languages and platforms for designing self organizing networks.

Special Issue on Load Balancing of Sensory Data for IoT Deep Learning Applications with Edge/Fog Computing (VSI-lbdl)
Submission Date: 2020-09-01

Overview: In the last decade, evolution of Internet of Things (IoT) has controlled various application domains such as emergency management, industrial applications, health care systems, real-time systems, and has been foreseen to flourish in future. The populace of IoT-based devices has been extended to 30 billion and expected to surpass 500 billion by 2030. This fact has led to various challenges, like how to extract and manage huge amounts of data that are constantly generated by IoT devices. This gives rise to solutions for IoT based on edge/fog computing that can move the data processing towards the edge of network as cloud-based deployments are not able to meet the increasing demands of clients. Nowadays, the Deep learning (DL) approach is used to extract information from IoT devices that are deployed in edge/fog computing environment due to its multi-layer structuring. DL in IoT is performed as layered processing in a distributed manner between edge and fog by extracting new features automatically for different problems. For the extraction of information from huge volume of real time data of IoT devices, data processing needs to be done close to the end devices where the data is produced (the edge). Since the prevailing edge nodes have inadequate processing capability, it is necessary to design and develop efficient load balancing strategies to optimize the performance of IoT devices for deep learning applications with edge/fog computing. The aim of this special section is to deal with various challenges such as hardware design, theoretical modeling, system architecture and analysis of deep learning applications in IoT using edge/fog computing. The focus is therefore on high-quality original papers aiming at demonstrating effective and efficient DL approaches for edge/fog, which at the same time considers data, device and infrastructure perspectives and related issues. This special section will cover recent technical advances with respect to IoT edge/fog computing, including strategies and protocols, architectures, emerging models, test-beds, applications, systems and field deployments. Nevertheless, numerous challenges exist for synchronization of the edge devices with other edge devices and fog under vibrant network circumstances and diverse processing competencies to deal with privacy issue and application-level performance. Topics: The topics of interest include: Protocols, models and architectures Resource allocation and management Data processing, distribution, management, and storage Computation offloading from IoT deep learning applications with edge/fog computing Fog-Cloud computing for IoT systems Security, privacy and trust AI and machine learning Performance evaluation Services and applications Edge-based platforms for IoT deep learning applications Novel edge/fog based deep learning models for IoT Simulation of edge IoT mining Methodologies for driving deep learning-based IoT edge/fog systems development Real applications and systems of deep learning at the edge

Special Issue on AI Models and Techniques for Edge-based Mission-Critical Applications (VSI-aie)
Submission Date: 2020-09-15

Recently, we have witnessed rapid deployment of various IoT-based applications, which is leading to Industry 4.0 revolution - the backbone of the underlying network infrastructure supported by 5G and upcoming 6G technologies. Some of the IoT-based applications (e.g., autonomous vehicles, e-healthcare, and smart surveillance systems) are being used for the benefits of the societies around the world. For example, doctors can diagnosis patients remotely in e-healthcare, autonomous vehicles can deliver necessary goods to customer premises, and smart robots can be used for surveillance. Most of these applications rely on AI-based control models and techniques to make independent decisions when necessary. However, most of these applications require “extra low-latency” and “ultra-high-speed” response time to provide Quality of Service (QoS) and Quality of Experience (QoE) to end users. It is, therefore, envisaged that 5G and 6G (i.e., beyond 5G - B5G) technologies can revolutionize the aforementioned applications in their respective domains in the years to come. Hence, with such infrastructure, low round trip delay is expected for most mission-critical applications such as, e-healthcare, robotic surgery, and surveillance. To support quick response time for mission-critical applications, quick decisions need to be made with respect to various data streams. For example, autonomous vehicles need to make quick decisions with respect to obstacles detection in their surroundings. In this context, AI-based techniques and models can be executed on edge servers, rather than remote cloud servers, to have real-time response. In B5G, various devices are expected to be inter-connected ubiquitously with the help of high communication coverage using dense deployed Heterogeneous Networks (HetNets) and machine-to-machine (M2M) communication. It creates high availability of the network resources close to the proximity of the end users, which in turn results in low latency for most of the applications. By off-loading different tasks directly to the edge servers, high performance gain can be achieved. Topics: The aim of this special section is to invite contributions from academia and industry on the following topics: mentioned below. AI models for network resources management using edge intelligence in 5G and 6G AI models for security and privacy preservation using edge intelligence in B5G AI models for location management of ubiquitous inter-connected devices using HetNets and M2M AI techniques for power and energy management using edge intelligence in B5G

Special Issue on Visual Servoing and its Applications (VSI-ibvs)
Submission Date: 2020-10-15

Visual servoing task is to control the pose of a robotic system, relative to a target, using visual features extracted from an image. Advanced robot systems often integrate up-to-date sensors, vision systems, and visual servoing techniques to deal with non-static target objects of various shapes and colors. The environment a robot is immersed in its orientation, and its motion can be described through visual information. The camera may be carried by the robot or fixed in the surroundings, known as endpoint closed-loop (eye-in-hand) and endpoint open-loop, respectively. Visual servoing has proven to be useful in a wide range of real-world applications, such as military, medical devices, trade, search and rescue, security, among many others. For instance, visual servoing techniques can be applied on unmanned vehicles, which can be used for surveillance, road-traffic control, border inspection, and reserved areas supervision, to provide visual information from the surroundings. Nowadays, the study on enhancing the autonomy of these vehicles has focused on navigation and formation control, target recognition, and tracking, among many others, by improving their visual capabilities. For example, the formation control in unmanned aerial vehicle (UAV) swarms is used in applications like searching and mapping to fly in groups above vast areas for goods delivery, tracking and even locating and following military targets. Visual servoing must produces the necessary commands to maintain the vehicle attitude and define the flight path based on the provided information from onboard sensors. Improving the autonomy of robots is still one of the challenges facing visual servoing and there are various ongoing studies in this field, where each system may differ from others in size, appearance, type of power plant, and more; due to these differences, they may also show distinct characteristics, but the equipment employed for evaluating their position and orientation is usually the same, which consists of inertial measurement units (IMU) and vison sensors. One of the flaws of using inertial information for motion is the accumulation of small errors on estimating the robot position, which consequently results in drift and deviation in determining its location over time. In modern motion equipment, the global positioning system (GPS) information is used for continuously correcting the IMU estimations and solving this problem, but in the event of interference or disconnection of the GPS signal, the position and motion error should remain and therefore visual servoing can be used for guidance and navigation in different kind of applications to improve the robot autonomy by feedback control of pose and motion through information acquired by onboard vision sensors. Topics: The topics of interest, listed below, are aimed to show continuing efforts provided in the domain of Visual Serevoing applications. Control system design for camera-carrying moving platforms. Image processing algorithms for feature extraction. Stability improvement. Target location and recognition.

Special Issue on Recent Advances and Challenges in Intelligent Sliding Mode Control for Modern Industrial Systems: Soft Computing Solutions (VSI-smc)
Submission Date: 2020-12-30

Overview In the rising trend of Industry 4.0, manufacturing industries have been experiencing significant changes with the increased untilization of machine learning, big data, aritificial intelligence, and intelligent automation. Modern industrial equipments and systems have been intensively used in wide applications to achieve a higher level of automation, e.g., for smart grids, renewable energy systems, robots, transportation and autotomotive industries. These changes requires better performance of the industrial systems in terms of robustness, reliablity, design and implementation simplicity, and intelligence. Sliding mode control (SMC), as an efficacious and powerful control methodology, is playing an essential role in meeting the performance requirements for modern industrial systems. The merits of SMC are high robustness against disturbances and parameter variations, reduced-order system design, simple control structure, computational simplicity for implementation, and fast dynamic response. Academics and engineers are working on further improving the convergence and robustness peformance, resulting in the dramatic development of the SMC methods. In spite of various research, the major technical problems of SMC are still challenging, particularly for modern industrial systems. As such, much of the recent SMC research has focused on the intergration with soft computing (SC) technologies, such that not only is the SMC more intelligent and flexible facing complex industrial environment, but also stronger robustness can be ensured. Meanwhile, the latest advances of microcontrollers, digital signal processors, sensors, etc. also facilitate the practical implementation of adavanced and intelligent SMC designs for complex industrial systems. The aim of this Special Section is to focus on the latest developments in the SC-based intelligent SMC for industrial systems, such as fuzzy logic (FL)-based SMC, neural network (NN)-based SMC, probabilistic reasoning (PR)-based SMC, SC integration-based SMC, etc. Meanwhile, practical technical issues and challenges of the intelligent SMC in various industrial applications should also be addressed.

Special Issue on Recent Advances and Challenges in Quantum-Dot Cellular Automata (VSI-qca)
Submission Date: 2020-12-31

Quantum computers promise dramatic improvements in our ability to efficiently solve classically intractable problems ranging from cryptosystems to simulation of quantum systems, and to optimization and machine learning. Quantum computing has attracted attention in the past two decades because it was found that computers exploiting quantum mechanics are able to outperform classical digital computers in certain areas like factoring integers and searching. Developments in the field of quantum computing have been strongly impacted by the paradigm of quantum-dot cellular automata (QCA), a scheme for molecular/metal/semiconductor electronics in which information is transmitted and processed through electrostatic interactions in an array of cells. QCA is a revolutionary computing paradigm that is well suited to nano-electronic implementation and scaling to molecular dimensions. In QCA, binary information is encoded in the position of single electrons among a group of dots forming a cell. This represents a significant break with the transistor-based paradigm in which information is encoded by the state of the transistor current switch. In QCA, electrons switch between quantum dots within a cell, but no current flows between cells. This leads to extremely low power dissipation, avoiding the problem of heat generation that ultimately limits the integration density of transistor circuits. QCA cells used for classical computing applications are mostly fully polarized during the operation. Dissipation plays a positive role helping the system to stay near the ground state. Unlike classical digital applications, quantum computing ideally needs coherence for correct operation. In the case of quantum computing, the cells are not fully polarized: they can be in a superposition of the P= +1 and -1 basis states. Similarly, a cell line can be in a superposition of the multi-qubit product states. In order to distinguish QCA applied for quantum computing from the classical digital QCA, the notion of coherent QCA (CQCA) can be explored. The aim of this special section is to explore solutions for major challenge in the area of QCA-based digital circuits. It includes the basics of new logic functions and novel digital circuit designs, Quantum Computing with QCA, new trends in quantum and quantum-inspired algorithms and applications, innovative layout methods, advanced EDA tools and algorithms to support QCA designers. Topics: Following are the main topic of interest: Quantum computer architecture; Performance evaluation methods for quantum networks New tools to design/build/optimize quantum hardware devices and quantum software; Design methodologies for and scalable quantum-computing systems; Emerging trends in quantum algorithms; Application case studies and evaluations; Testing, design for testability, built-in self-test in QCA technology. QCA-based logic structures and interconnections; Innovative clock schemes to control data flow directionality; Smart formulations of logic equations; Logic gates and digital circuits designs; Software development tools for the design and the characterization of QCA circuits; Area, power, and thermal analysis and design in QCA nano-technology.
