Special Issues
Special Issue on Towards the Internet of Data: Applications, opportunities and Future Challenges
Submission Date: 2017-08-01

In the new digital era, the Internet of Things (IoT) is a now a familiar concept for many, producing a sheer volume of data generated by an ever increasing network of connected devices that collect and exchange information. A research challenge is how to manage and process the data to adapt the issues of data mining and analysis in the IoT. There is no simple answer to the question of where and how data should be processed, analysed and stored. In this scenario, the Internet of Data (IoD) represents a concept of network composed by data entities coming from the Interne of Things (IoT). The IoD can be considered an extension of the IoT into the digital world, since the amount of data being collected is staggering. The opportunities created by IoD have the potential to be infinite. The IoD presents an ambitious purpose; organizing the data to be interconnected as a network in order to infer useful information for data analysis and creates useful, customized and location-based services. By means of parallel and distributed computing methodologies it will be possible to opportunely solve large-scale problems and process data. This special issue focused on the Internet of Data (IoD) seeks high-quality papers addressing recent advances in data storing, processing and analysis in the IoD realm, also exploiting parallel and distributed computing techniques to smartly manage the massive volume of data.

Special Issue on Parallel Computing in Modelling and Simulation
Submission Date: 2017-09-15

Model development for the simulation of the evolution of artificial and natural systems is essential for the advancement of Science. Recently, the increasing power of computers has allowed to considerably extend the application of parallel computing methodologies in research and industry, but also to the quantitative study of complex phenomena. This has permitted a broad application of numerical methods for differential equation systems (e.g., FEM, FDM, etc.) on one hand, and the application of alternative computational paradigms, such as Cellular Automata, Genetic Algorithms, Neural networks, Swarm Intelligence, etc., on the other. These latter have demonstrated their effectiveness for modelling purposes when traditional simulation methodologies have proven to be impracticable. This Special issue aims to provide a platform for a multidisciplinary community composed of scholars, researchers, developers, educators, practitioners and experts from world leading Universities, Institutions, Agencies and Companies in Computational Science, and thus in the Parallel Computing for Modelling and Simulation field. The intent is to offer an opportunity to express and confront views on trends, challenges, and state-of-the art in diverse application fields, such as engineering, physics, chemistry, biology, geology, medicine, ecology, sociology, traffic control, economy, etc.

Special Issue on High-Performance Computing in Edge Computing Networks
Submission Date: 2017-10-01

High-performance computing (HPC) describes the application of parallelization and distribution algorithms or techniques to connected computing units, to perform more complex tasks in a faster manner than a single unit could do alone. Over the past two decades, the operation speeds of HPC has increased exponentially. Riding on such growth, while HPC continuously advances in its traditional domain of theoretical science and software development, it is increasingly becoming a prevalent solution to a wide range of emerging telecommunication technologies. Edge Computing Networks and Telecommunication technologies support information transmission over significant distance via distributed and connected communication devices. Rapid innovations in transmission, switching, processing, analyzing, and retrieval of information are vital for the success of a wide range of emerging telecommunication technologies, including connected sensors and IoT devices, smart grid, smart cities, software-defined networks, network function virtualization, data-driven cognitive networking, cyber security, green communications, etc. The class of computational problems that need to be tackled, such as combinatorial optimization, agent-based modelling, massive data analysis, parallel discrete event network simulations, pose new challenges in design or develop the above emerging telecommunication technologies. HPC is essential to address these computational challenges. Greatly relevant is the contribution that modelling and evaluation techniques (both analytical and simulation based) may bring to the design and the implementation of such complex HW/SW architectures, to dominate various concurring requirements and guide decision processes that lead to an effective result. The aim of this special issue is to explore how HPC as a research tool enhances emerging telecommunication technologies, and hence present a completing panorama of the state-of-the-art quality research efforts on applying HPC to telecommunications. In addition, the discussion of future and emerging challenges, advances, and applications of HPC and related technologies are all the interests of this special issue. It is hoped that the published research issues or solution guidelines will inspire further research in this very important area of various telecommunication system or algorithm design, as well as provide comprehensive information for researchers, students in ICT, program developers, military and government organizations, and business professionals.

Special Issue on Cloud-of-Things and Edge Computing: Recent Advances and Future Trends
Submission Date: 2018-01-30

In recent years, Cloud-assisted Internet of Things (Cloud-of-Things or in short CoT) has emerged as a revolutionary paradigm that enables intelligent and self-configuring (smart) IoT devices and sensors to be connected with the cloud through the Internet. This new paradigm enables the resource-constrained IoT devices to get the benefit from Cloud's powerful and scalable high-performance computing and massive storage infrastructure for real-time processing and storing of the IoT data as well as analysis of the processed information under context using inherently complex models. At the same time, cloud can benefit from IoT by allowing its users to build applications that can use and handle these smart IoT objects interconnected and controlled through software services using cloud infrastructure. Thus, the CoT paradigm can stimulate the development of innovative and novel applications to various areas such as smart cities, smart homes, smart grids, smart agriculture, smart transportation, smart healthcare, etc. to improve all aspects of people's life. However, currently the CoT paradigm is facing increasing difficulty to handle the Big data that IoT generates from these application use cases. As billions of previously unconnected devices are now generating more than two exabytes of data each day, it is challenging to ensure low latency and network bandwidth consumption, optimal utilization of computational recourses, scalability and energy efficiency of IoT devices while moving all data to the cloud. Hence, in recent times, this centralized CoT model is undergoing a paradigm shift towards a decentralized model termed as edge computing, that allows data computing, storage and service supply to be moved from Cloud to the local edge devices such as smartphones, smart gateways or routers and local PCs that can offer computing and storage capabilities on a smaller scale in real-time. Edge computing pushes data storage, computing and controls closer to the data source(s) instead of performing in a centralized local server or devices as in the case of Fog computing; therefore, enables each edge device to play its own role of determining what information should be stored or processed locally and what needs to be sent to the cloud for further use. Thus, edge computing complements CoT paradigm in terms of high scalability, low delay, location awareness, and allowing of using local client computing capabilities in real time. While researchers and practitioners have been making progress within the area of edge computing, still there exists several issues that need to be addressed for CoT paradigm. Some of these issues are: novel network architecture and middleware platform for edge and CoT paradigm considering emerging technologies such as 5G wireless networks, semantic computing; edge analytics for Big data; novel security and privacy methods; social intelligence into the edge node to host CoT applications; and context-aware service management on the edge with effective quality of service (QoS) support and other issues.
