The Internet of Things (IoT) is a promising technology which tends to revolutionize and connect the global world via heterogeneous smart devices through seamless connectivity. current demand for machine-type communications (MTC) has resulted in variety communication technologies with diverse service requirements achieve modern IoT vision. More recent cellular standards like long-term evolution (LTE) have been introduced mobile but are not well suited low-power low data rate such as devices....
The three previous industrial revolutions profoundly transformed agriculture industry from indigenous farming to mechanized and recent precision agriculture. Industrial paradigm greatly improves productivity, but a number of challenges have gradually emerged, which exacerbated in years. Industry 4.0 is expected reshape the once again promote fourth agricultural revolution. In this article, first, we review current status along with lessons learned industrialized production patterns,...
Software defined networking (SDN) brings about innovation, simplicity in network management, and configuration computing. Traditional networks often lack the flexibility to bring into effect instant changes because of rigidity also over dependence on proprietary services. SDN decouples control plane from data plane, thus moving logic node a central controller. A wireless sensor (WSN) is great platform for low-rate personal area with little resources short communication ranges. However, as...
Internet of Things (IoT) has revolutionized the traditional where only human-centric services were offered. It enabled objects to have ability connect and communicate through Internet. IoT several applications such as smart water management systems. However, they require high energy-efficient sensor nodes that are able across long distance. This motivates development many Low-Power Wide Area Networks (LPWAN) technologies, LoRa, fulfill these requirements. Therefore, in this paper, we survey...
The novel coronavirus (COVID-19), declared by the World Health Organization (WHO) as a global pandemic, has brought with it changes to general way of life. Major sectors world industry and economy have been affected Internet Things (IoT) management framework is no exception in this regard. This article provides an up date survey on how pandemic such COVID-19 IoT technologies. It looks at contributions that associated sensor technologies made towards virus tracing, tracking spread mitigation....
The Internet of Things (IoT) paradigm plays a vital role for improving smart city applications by tracking and managing processes in real-time. One the most significant issues associated with is solid waste management, which has negative impact on our society’s health environment. traditional management process begins created residents disposed garbage bins at source. Municipal department trucks collect move it to recycling centers fixed schedule. Municipalities companies fail keep up...
Leakage detection and localization in pipelines has become an important aspect of water management systems. Since monitoring leakage large-scale distribution networks (WDNs) is a challenging task, the need to develop reliable robust leak technique essential for loss reduction potable WDNs. In this paper, some existing techniques are discussed open research areas challenges highlighted. It concluded that despite numerous efforts advancement technologies, large scope still further domain. One...
The increased use of Industrial Wireless Sensor Networks (IWSN) in a variety different applications, including those that involve critical infrastructure, has meant adequately protecting these systems become necessity. These cyber-physical improve the monitoring and control features but also introduce several security challenges. Intrusion detection is convenient second line defence case failure normal network protocols. Anomaly branch intrusion resource friendly provides broader generality...
Water scarcity and water stress issues pose a serious threat to the global population. The traditional way of manual meter reading is furthermore inconvenient time consuming, it wastes resources. This method also unable manage sustainable resources effectively since requires efficient, accurate reliable monitoring techniques that enable utilities sector consumers know level consumption in real-time. Real-time smart meters can be monitored by user are essential constitute key component...
The presence of missing data is problematic in most quantitative research studies. Water distribution systems (WDSs) are not immune to this problem. In fact, an inherent feature a WDS. There various techniques and methods address ranging from simply deleting the using complex algorithms impute data. This paper reviews different imputation options available traditional (such as deletion single imputation) more modern advanced multiple imputation, model-based procedures, machine learning...
Software-Defined Networking (SDN) is a network paradigm introduced to overcome the inherent challenges of traditional networks. Its architecture either deployed with single controller or multiple controllers. While first not suitable for large-scale networks, latter confronted placement problem (CPP) in environment. CPP involves challenge deploying optimal number controllers within while meeting certain performance requirements considered conflicting nature such as reliability, load...
The Internet of Things (IoT) is a promising technology that allows numerous devices to be connected for ease communication. heterogeneity and ubiquity the various devices, openness in network, and, importantly, increasing number smart objects (or devices) have exposed IoT network security challenges vulnerabilities which include manipulative data injection cyberattacks such as denial service (DoS) attack. Any form intrusive or attacks on networks can create devastating consequences...
Wireless Sensor Network (WSN), which are enablers of the Internet Things (IoT) technology, typically used en-masse in widely physically distributed applications to monitor dynamic conditions environment. They collect raw sensor data that is processed centralised. With current traditional techniques state-of-art WSN programmed for specific tasks, it hard react any change environment beyond scope intended task. To solve this problem, a synergy between Software-Defined Networking (SDN) and has...
In recent times, distributed denial of service (DDoS) has been one the most prevalent security threats in internet-enabled networks, with many internet things (IoT) devices having exploited to carry out attacks. Due their inherent flaws, attacks seek deplete resources target network by flooding it numerous spoofed requests from a system. Research studies have demonstrated that DDoS attack considerable impact on and can result an extended operational outage if not detected. The detection...
