Submission Date: 2019-11-30

The monitoring ability of emerging technologies and applications to make them very suitable for extreme surveillance systems. A large number of applications related to extreme events, especially natural disasters, agriculture, water, forest, military, buildings, health monitoring, disaster relief & emergency management, area and industrial surveillance have already been studied from the emerging technologies perspective and most of these surveillance applications have attracted much research attention. Emerging technologies is increasingly becoming the most important and valuable source for insights and information in extreme events. It covers from everyone’s experiences to everything happening in the world. There will be lots of emerging technologies in extreme events surveillance video, disaster images, social media, voice and video, to name a few, only if their volumes grow to the extent that the traditional processing and analysis systems may not handle effectively Unmanned Aerial Vehicles (UAVs) empower people to reach endangered areas under emergency situations. By collaborating with each other, multiple UAVs forming a UAV network (UAVNet) could work together to perform specific tasks in a more efficient and intelligent way than having a single UAV. UAV Nets pose special characteristics of high dynamics, unstable aerial wireless links, and UAV collision probabilities. UAV networks may vary from slow dynamic to dynamic; have intermittent links and fluid topology.

Special Issue on Advanced Computing and Communication Technologies for Internet of Drones
Submission Date: 2019-12-01

Unmanned Aerial Vehicles (UAVs) which are commonly known as drones can be potential enablers for providing different type of solutions in a futuristic smart city. Initially, drones were restricted to sophistic areas like military operations due to their cost and limited technological advancements. But, nowadays, the advent of more affordable technologies are enabling drones in finding their way to our day to day usage application areas like logistics, remote monitoring, cinematography, agricultural monitoring, search and rescue, and 3D-mapping. The development on Internet of Drones (IoD) is enabling the design of new architectures, standards and technologies to make the drone operations as autonomous as possible. A few of the thrust areas of IoD research are computing, communication, security and privacy, energy and sustainability. The limited computing resources available with the drones so as to keep it lightweight must be utilized effectively in terms of processing, computing, sensing and analyzing. For this reason, in order to enable long operating durations during the flight, efficient mechanisms must be designed to optimize the computing processes and needs of the drones. The limited battery capacity hinders the progression of drones by limiting the flight time. However, the energy-efficient computing procedures and mechanisms can reduce the tendency of energy dissipation thereby elongating the flight times during hover. Moreover, the latest innovations in terms of energy harvesting, wireless energy transfer and solar plates has opened new doors for opportunistic energy replacement during the hover time of the drones. The deployment of drones in sensitive and consumer related applications make it necessary to design sustainable and eco friendly solutions which could utilize the limited computing facilities of drones to provide enhanced quality of services to the users. Although the distributed nature of IoD architecture provides various advantages in terms of scalability and autonomy, but it bring forward various mobility and controlling issues creating the need of special attention to the communication platforms also. The conventional network systems may not be very efficient in dealing with the dynamic requirements of IoD. Latest network paradigms such as software defined networking and network function virtualization provides new potentials of technological advancements in IoD communication architecture. Moreover, the next generation technologies such as-5G and NOMA also have shown a promising trends in the design of advanced communication solutions for IoD. As the drones are generally deployed in tough environments and terrains, therefore it is quite essential to provide a strong network and communication backbone. Otherwise, it may lead to adverse effects on the designed solutions or applications dependent on the drones. Security and privacy are yet another areas of concern for drones which needs focus of the research community as an attack on the IoD can be fatal and may lead to loses of lives and assets. There may be several solutions related to security and privacy but the applicability of these solutions with IoD perspective is questionable. Therefore, the applicability of those solutions in IoD needs to be analyzed keeping in view the nature of applications, limited computing and communication capabilities and the energy and sustainability constraints of drones. Moreover, the deployment of drones in consumer applications dealing with product delivery and logistics make it a compulsion to preserve the identity of users and the sensitive information associated with them. Blockchain can be a viable solution for preserving the data integrity and securing the entire transactional process involved. But, the limited computing capabilities require lightweight solutions which right now are not feasible in the available blockchain variants. Moreover, new cryptographic primitives need to be designed to protect and preserve the IoD from adversaries and attackers. Keeping in view of the need of technological advancements in different enabling domains related to IoD, this special issue provides a platform to the research, academia and industrial technocrats to present their ideas and solutions from various perspectives related to drones. Thus, for this special issue , the deeply investigated works describing both theoretical and practical evaluations related to the design, analysis and implementation of secure and sustainable computing and communication technologies for IoD are invited. Some of the desired topics include, but are not limited to the following: Cloud and big data technologies for drone networks. Edge as a service for drones in smart communities.

Submission Date: 2020-02-28

The past couple of decades have substantiated the aggrandizement of Wireless Sensor Networks (WSNs) in academia and industry. In the WSN, numerous sensor nodes are deployed and networked to perlustrate a specified region, such that the inquisitive data can be sensed, processed, stored and collected.

Special Issue on Intelligent Edge: When Machine Learning Meets Edge Computing
Submission Date: 2020-03-15

The explosion of the big data generated by ubiquitous edge devices motivates the emergence of a new computing paradigm: edge computing. It has attracted attention from both academia and industry in recent years. In edge computing, computations are deployed mainly at the local network edge rather than at remote central computing infrastructures, thereby considerably reducing latency and possibly improving computation efficiency. This computing model has been applied in many areas such as mobile access networks, Internet of Things (IoT), and microservices, enabling novel applications that drastically change our daily lives. As a second trend, a new era of Artificial Intelligence (AI) research has delivered novel machine learning techniques that have been utilized in applications such as healthcare, industry, environment engineering, transportation, smart home and building automation, all of which heavily rely on technologies that can be deployed at the network’s edge. Therefore, intuitively, marrying machine learning techniques with edge computing has high potential to further boost the proliferation of truly intelligent edges. In light of the above observations, in this special issue, we look for original work on intelligent edge computing, addressing the particular challenges of this field. On one hand, conventional machine learning techniques usually entail powerful computing infrastructures (e.g., cloud computing platforms), while the entities at the edge may have only limited resources for computations and communications. This suggests that machine learning algorithms or, at least, the implementations of machine learning algorithms, should be revisited for edge computing, which represents a considerable risk and challenge at once. On the other hand, the adapted deployments of machine learning algorithms at the edge empower the “smartification” across different layers, e.g., from network communications to applications. This in turn allows new applications of machine learning and artificial intelligence, opening up new opportunities. The goal of this special issue is to offer a venue for researchers from both academia and industry to present their solutions for re-designing machine learning algorithms compatible to edge computing, and for building intelligent edge by machine learning techniques, possibly revealing new, compelling use cases. Relevant topics include, but are not limited to: l System architectures of intelligent edge computing l Modeling, analysis and measurement of intelligent edge computing l Machine learning algorithms and systems for edge computing l Machine learning-assisted networking and communication protocols for or using edge computing l Intelligent mobile edge computing l Architectures, techniques and applications of intelligent edge cloud l Resource management for intelligent edge computing l Security and privacy of intelligent edge computing l Data management and analytics of intelligent edge computing l Intelligent edge-cloud collaborations l Programming models and toolkits for intelligent edge computing l Distributed machine learning algorithms for edge computing l Smart applications of edge computing

Special Issue on Autonomous Learning-Based Algorithm for Heterogeneous Cellular Networks
Submission Date: 2020-03-30

The spectrum bands of the multiple base stations comprise the sets of orthogonal wireless channels and spectrum usage scenarios the device to device pairs transmit over the dedicated frequency bands and the device to device pairs operate on the shared cellular channels. The goal of each device pair is to jointly select the wireless channel and power level to maximize its reward, defined as the difference between the achieved throughput and the cost of power consumption, constrained by its minimum tolerable signal-to-interference-plus-noise ratio requirements. We formulate this problem as a stochastic non-cooperative game with multiple players where each player becomes a learning agent whose task is to learn its best strategy and develop a fully autonomous multi-agent Q-learning algorithm converging to a mixed-strategy Nash equilibrium. The learning algorithm shows relatively fast convergence and near-optimal performance after a small number of iterations. Potential topics included, but not limited Reinforcement Learning for self organization and power control of two-tier heterogeneous networks · Optimal new site deployment algorithm for heterogeneous cellular networks· Energy cost minimization in heterogeneous cellular networks with hybrid energy supplies· Configuration algorithm for service scalability in heterogeneous cellular networks· Q-learning based heterogeneous network selection algorithm· Bayesian reinforcement learning-based algorithm for heterogeneous cellular networks· Machine learning paradigms for next-generation communication networks · Online distributed user association for heterogeneous radio access network
