A Review on Software‐Defined Networking for Internet of Things Inclusive of Distributed Computing, Blockchain, and Mobile Network Technology: Basics, Trends, Challenges, and Future Research Potentials

Internet of things (IoT) and software‐defined networking (SDN) are two relatively recent developments in the field of communication technology that have emerged in response to the growing demand for more efficient, flexible, and dynamic network architectures. As both of these concepts are new, they have received increasing attention from academic or industrial sources to emphasize their potential for integration. This study is aimed at reviewing the literature on SDN for IoT (SDN‐IoT) published from 2014 to 2022 and presenting insights and directions for future research, with a particular focus on cloud, fog, and edge computing. The study collects data from Science Direct, IEEE Explore, and Google Scholar and objectively selects 126 papers and conducts metadata analysis. The study articulates the challenges of managing and orchestrating IoT systems and how SDN can be used to address these challenges by enabling dynamic and flexible network configurations. It delineates not only the function of blockchain (BC) technology in securing and managing IoT networks but also how SDN can be utilized to incorporate BC‐based solutions. Additionally, the potential of SDN for mobile networks is explored, which are increasingly being used to support IoT devices. Finally, this study outlines the issues, challenges, and potential future research directions that may present opportunities for the researchers working in this field, underscoring the demand for more in‐depth investigation and advancement.

Mobile cloud computing for indoor emergency response: the IPSOS assistant case study

Mobile Cloud Computing and Internet of Things provide pervasive connected infrastructures that allow people to be continuously connected with other people, services, and objects. However, technologies for multi-paradigm distributed computing are still in their infancy and lack of standardization and experimentation as pervasive well-being technology. In this article, we discuss about the use of mobile cloud computing technologies to devise a new generation of software systems for Indoor Emergency Response with better automation, flexibility, efficiency, and rich user experience. To this end, we present a prototype cloud-enabled mobile app, named IPSOS Assistant, for monitoring people well-being and managing emergencies in indoor environments. Such a prototype application is aimed at increasing the reliability and safety in indoor workplaces to prepare for and manage a variety of emergencies or incidents by giving people assistance (e.g., showing available escape routes in case of fire) and by taking advantage from the social contribution of other people located nearby in the same building. The IPSOS Assistant app has been designed and developed since 2014 as an academic/research pilot project. In this article, we share the design, discuss faced challenges, and report our experiments and lessons that we learned while developing such a kind of application.

Design and Development of Trade Detector Based on Distributed Computing Technology

J2EE is set for the distributed computing realization of API, services and protocols developed by SUN. The design objective of J2EE computer development tool is to provide a simple, easy operation development platform for developers, which can reduce the cost of development, shorten the development cycle, and improve the comprehensive performance of computer system. In this paper, we use JSP calculation vessel function module of J2EE to improve the computer economic detection system, and establish data connection between system and the HTML Webpage, which realizes the real-time and continuous detection of the economy. Finally, based on the external demand and exports of industrial products in an area, we detect trade transactions in the region, and do mathematical statistics using the J2EE system, and finally get the trade scale. It provides a new computer method for the research of export trade and economic detection.

From Quantity To Quality: Massive Molecular Dynamics Simulation of Nanostructures under Plastic Ddeformation in Desktop and Service Grid Distributed Computing Infrastructure

The distributed computing infrastructure (DCI) on the basis of BOINC and EDGeS-bridge technologies for high-performance distributed computing is used for porting the sequential molecular dynamics (MD) application to its parallel version for DCI with Desktop Grids (DGs) and Service Grids (SGs). The actual metrics of the working DG-SG DCI were measured, and the normal distribution of host performances, and signs of log-normal distributions of other characteristics (CPUs, RAM, and HDD per host) were found. The practical feasibility and high efficiency of the MD simulations on the basis of DG-SG DCI were demonstrated during the experiment with the massive MD simulations for the large quantity of aluminum nanocrystals ($\sim10^2$-$10^3$). Statistical analysis (Kolmogorov-Smirnov test, moment analysis, and bootstrapping analysis) of the defect density distribution over the ensemble of nanocrystals had shown that change of plastic deformation mode is followed by the qualitative change of defect density distribution type over ensemble of nanocrystals. Some limitations (fluctuating performance, unpredictable availability of resources, etc.) of the typical DG-SG DCI were outlined, and some advantages (high efficiency, high speedup, and low cost) were demonstrated. Deploying on DG DCI allows to get new scientific $\it{quality}$ from the simulated $\it{quantity}$ of numerous configurations by harnessing sufficient computational power to undertake MD simulations in a wider range of physical parameters (configurations) in a much shorter timeframe.

The Design and Implementation of Baiyangdian Tourism Business System Based on Web Service

If the tourism e-business system has the characteristics of platform independence, scalability and portability, it will be useful for improving the level of service and management of the tourism, and further quicken the step of tourism industry. Web Service provides a kind of new distributed computing technology; it can embody business application services by standard XML protocol and information format on Internet or Intranet. According to the demands of a typical tourism business platform, this paper designed a loosely coupling and easily scalable system scheme, what’s more, carried it out in the final. All attained the expect goal.

Security on the US fusion grid

The National Fusion Collaboratory project is developing and deploying new distributed computing and remote collaboration technologies with the goal of advancing magnetic fusion energy research. This has led to the development of the U.S. fusion grid (FusionGrid), a computational grid composed of collaborative, compute, and data resources from the three large U.S. fusion research facilities and with users both in the U.S. and in Europe. Critical to the development of FusionGrid was the creation and deployment of technologies to ensure security in a heterogeneous environment. These solutions to the problems of authentication, authorization, data transfer, and secure data storage, as well as the lessons learned during the development of these solutions, may be applied outside of FusionGrid and scale to future computing infrastructures such as those for next-generation devices like ITER.

Distributed Animation Rendering Based on Grid Computing

Rendering high quality animations from 3D models is a computationally expensive and challenging task. Recently, distributed computing technologies have been deployed for real-time and effective animation rendering. However, specialized programming skills and specific hardware or software are required to perform animation rendering on the basis of distributed computing technology. Therefore, a distributed computing technology to enable efficient and easy execution of animation rendering is required. In this paper, we propose a method for distributed animation rendering based on Grid computing. The method we propose does not impose any special distributed computing technology on users' and it facilitates effective implementation of distributed animation rendering. In this research, we also developed a scheduler that automatically distributes the animation rendering task to the resources in a Grid computing environment. We constructed a prototype based on the proposed method and confirmed its effectiveness through several animation rendering experiments.
