Abstract The Corona Virus Disease 2019 (COVID-19) effect has made
telecommuting and remote learning the norm. The growing number of
Internet-connected devices provides cyber attackers with more attack vectors.
The development of malware by criminals also incorporates a number of
sophisticated obfuscation techniques, making it difficult to classify and detect
malware using conventional approaches. Therefore, this paper proposes a
novel visualization-based malware classification system using transfer and
ensemble learning (VMCTE). VMCTE has a strong anti-interference ability.
Even if malware uses obfuscation, fuzzing, encryption, and other techniques
to evade detection, it can be accurately classified into its corresponding
malware family. Unlike traditional… More >

Abstract In the past decade, blockchain has evolved as a promising solution to develop secure distributed ledgers and has gained massive attention.
However, current blockchain systems face the problems of limited throughput,
poor scalability, and high latency. Due to the failure of consensus algorithms in
managing nodes’identities, blockchain technology is considered inappropriate
for many applications, e.g., in IoT environments, because of poor scalability.
This paper proposes a blockchain consensus mechanism called the Advanced
DAG-based Ranking (ADR) protocol to improve blockchain scalability and
throughput. The ADR protocol uses the directed acyclic graph ledger, where
nodes are placed according to their ranking positions… More >

Abstract Metaheuristic algorithms, as effective methods for solving optimization problems, have recently attracted considerable attention in science
and engineering fields. They are popular and have broad applications owing
to their high efficiency and low complexity. These algorithms are generally
based on the behaviors observed in nature, physical sciences, or humans. This
study proposes a novel metaheuristic algorithm called dark forest algorithm
(DFA), which can yield improved optimization results for global optimization problems. In DFA, the population is divided into four groups: highest
civilization, advanced civilization, normal civilization, and low civilization.
Each civilization has a unique way of iteration. To verify DFA’s… More >

Abstract Physical sensors, intelligent sensors, and output recommendations are all examples of smart health technology that can be used to
monitor patients’ health and change their behavior. Smart health is an
Internet-of-Things (IoT)-aware network and sensing infrastructure that
provides real-time, intelligent, and ubiquitous healthcare services. Because of
the rapid development of cloud computing, as well as related technologies
such as fog computing, smart health research is progressively moving in
the right direction. Cloud, fog computing, IoT sensors, blockchain, privacy
and security, and other related technologies have been the focus of smart
health research in recent years. At the moment, the focus… More >

Abstract The performance of Wireless Sensor Networks (WSNs) is an
important fragment of the Internet of Things (IoT), where the current WSNbuilt IoT network’s sensor hubs are enticing due to their critical resources. By
grouping hubs, a clustering convention offers a useful solution for ensuring
energy-saving of hubs and Hybrid Media Access Control (HMAC) during the
course of the organization. Nevertheless, current grouping standards suffer
from issues with the grouping structure that impacts the exhibition of these
conventions negatively. In this investigation, we recommend an Improved
Energy-Proficient Algorithm (IEPA) for HMAC throughout the lifetime of
the WSN-based IoT. Three consecutive segments… More >

Abstract The growth of the internet and technology has had a significant
effect on social interactions. False information has become an important
research topic due to the massive amount of misinformed content on social
networks. It is very easy for any user to spread misinformation through the
media. Therefore, misinformation is a problem for professionals, organizers,
and societies. Hence, it is essential to observe the credibility and validity of the
News articles being shared on social media. The core challenge is to distinguish the difference between accurate and false information. Recent studies
focus on News article content, such as News titles… More >
