    Environmentally sustainable metropolitan environments are characterized by their ability to effectively produce and distribute power while reducing their impact on the environment. Smart homes are essential in smart cities since they enhance sustainability and efficiency in urban settings. A key advantage of smart homes is their capacity to diminish energy use and carbon emissions. This is accomplished by optimizing energy consumption in home appliances, which is customized to fulfill the individual requirements and preferences of consumers. However, there is still a need for further academic research to investigate and improve the functioning of intelligent residential homes in microgrids. To efficiently manage microgrids, it is crucial to gather and analyze large amounts of electrical data related to power production from microgrid sources and energy consumption of the loads. This study examines the use of Non-Intrusive Load Monitoring (NILM) methods to monitor electrical parameters of different loads in microgrids. The research focuses on the application of affordable smart meters that are equipped with Internet of Things (IoT) capabilities. An empirical study showcases the possibility of collecting significant data on microgrid operation via the deployment of an operational microgrid that integrates a hybrid wind-solar power source with a variety of home appliances.

    In recent times, there has been a growing recognition of the importance of circular business models (CBM) in advancing environmental sustainability. However, the relationship between CBM and the Internet of Things (IoT) has received little attention in current academic discussions. This paper seeks to fill this gap by initially identifying four key capabilities of IoT—namely monitoring, tracking, optimization, and design evolution—using the ReSOLVE framework to enhance the performance of CBM. Subsequently, through a systematic literature review employing the PRISMA approach, the paper examines how these IoT capabilities contribute to the principles of "Reduce, Reuse, Recycle, Redesign, Remanufacture, and Recover" (the 6R) and CBM. The analysis utilizes cross-section heatmaps and relationship frameworks to elucidate the interaction between CBM and IoT. Additionally, the paper evaluates the quantitative impact of IoT on potential energy savings within CBM contexts. The findings underscore a predominant focus on assessments related to Loop and Optimize business models, where IoT significantly aids through tracking, monitoring, and optimization capabilities. However, there is a noticeable scarcity of (quantitative) case studies concerning Virtualize, Exchange, and Regenerate CBM models, indicating the necessity for further research in these domains. Notably, IoT exhibits promise in reducing energy consumption by approximately 20–30% across referenced applications in the literature. Nonetheless, challenges such as IoT hardware, software and protocol energy consumption, interoperability, security, and financial investments may hinder its wider adoption in CBM practices.

    Currently, cloud computing provides the necessary infrastructure and software services to provide the requested services needed by users on the Internet. Due to the spectacular growth of cloud computing, the number of users and the number of demands are increasing rapidly, which creates a high workload on servers and computing resources. In this situation, for the optimal use of resources, the need for an efficient and effective management approach is fully felt. For this purpose, game theory has been used. The game structure is designed in such a way that the leader (leader) owns a large number of resources and plans the allocation of resources based on the request received from mobile users. The goal from the leader's point of view is to minimize the cost of using the resources located in the fog nodes, on the other hand, the goal considered from the mobile users' point of view is to minimize the cost of responding and transmitting the message to the desired fog node. For this purpose, the entire region is divided into regions and a fog node is considered for each region. The main goal of this research is to reduce the average delay in the provision of services related to Internet of Things applications in cloud computing platforms. For this purpose, an attempt is made to provide a new method for allocating multiple tasks in mobile collective monitoring based on fog computing in the Internet of Things using the inverse Stackelberg game theory with the help of fuzzy logic and deep reinforcement learning algorithm.

    In this article, Multitrial vector-based differential evolution algorithm (MTDE) is proposed as energy and cost management controller under Time of Use (TOU) tariff in grid associated domestic PV-wind power system tied with battery storages. To enrich the energy efficiency of a proposed power system, two optimisation algorithms are proposed in the scheduling operation. TOU billing is a cost- reflective power pricing strategy that has been found as an effective way to reduce peak energy consumption in the residential segment everywhere the world, mainly in industrialised nations. In the optimisation maximizing the cost benefit of the household energy is taken as the objective and the dispatching ratio of electricity sold to the grid and used locally is treated as the optimisation variable. Using MATLAB, the performance of proposed MTDE in the aspect of daily cost benefit and revenue growth rate are presented with the comparative analysis of gravitational search algorithm and conventional self-made for self-consumed and rest for sale (SFC&RFS) mode -based energy management controller. In comparison to the SFC&RFS mode, the GSA-based cost optimization offers a 21.46% increase in revenue growth, while it is improved to 38.7% using proposed MTDE algorithm. The paper also addresses the significance of fuzzy logic based maximum power point tracking (MPPT) of solar PV in enhancing the energy management of the proposed system. The prototype of fuzzy logic MPPT for 10 W solar panel is presented and the tracked maximum power is visualized using Thingspeak IoT cloud server. The tracking speed of the MPPT can be increased by introducing machine learning algorithms at the cost of memory and complexity. In this article, the linear regression-based machine learning algorithm is implemented in the hardware prototype by utilizing the dataset aggregated from fuzzy MPPT and hence the proposed MPPT inherits the characteristics of the fuzzy MPPT with increased tracking speed. Around 75 % data are used for training, 25% of data are used to test the model and it is observed that the root mean square error (rmse) is 5.1334 and mean square error is 26.3521 and the model is utilized as MPPT for the real-time inputs.

    BACKGROUND AND OBJECTIVES

    Land-based aquaculture operations, at present,  are intensively conducted to meet the ever-growing demand for food consumption. Floating net cages are one of the traditional methods commonly used by Indonesian fishermen for river fish farming. Increased human activities along the Musi River and coastline have resulted in pollution and waste in the river waters and fluctuating water quality. Yet, floating net cage owners still manually assess the water quality. This study aims to develop an early warning system for water quality and create a decision-making program as a reference for fishermen to relocate floating net cages when the river water quality deteriorates.

    METHODS

    The device was tested at 39 locations within a radius of approximately 3400 meters, and the distance between locations varied between 55 and 334 meters. The river was divided into three sections: the river coast, the middle section, and the other river coast. Water quality sensors were placed at a depth of 0–20 centimeters from the surface of the Musi River, with measurement durations at each location ranging from 1 to 40 minutes. Direct measurements of the Musi River's water quality were obtained by monitoring the water quality using an internet-based computer application. A decision-making Python program utilizing fuzzy logic was then executed to evaluate the suitability of the river water quality for fish cultivation. The program's input variables comprise water temperature, potential of hydrogen, and dissolved oxygen sensor data. Meanwhile, the program output recommends floating net cage owners to either "Stay in position" or "Move." Water quality warnings that exceed the upper and lower threshold limits are displayed using light-emitting diode indicators and a buzzer.

    FINDINGS

    Overall, the water quality values of the Musi River at the test locations generally indicated stable and suitable conditions for river fish cultivation. The average water quality values were 29.20 degrees Celsius for temperature, 3.98 milligrams per liter for dissolved oxygen, and a potential of hydrogen of 6.42. From all the data obtained during the decision-making program, 36 locations suggested that the floating net cages should "Stay in position." Meanwhile, the three remaining locations were recommended to "Move" as they exhibited poor water quality, with potential of hydrogen values below 6. Field observations indicated that these locations were situated near residential areas, factories/industries, and tributaries, which are highly susceptible to waste and pollution. The output of the decision-making program correlated with the issued warnings by the water quality warning indicators when the pH value exceeded the lower threshold limit.

    CONCLUSION

    The fuzzy logic method implemented in the Python program for decision-making regarding the relocation of floating net cages in river fish farming revealed the fluctuating water quality conditions of the Musi River within a specific time duration. These conditions correlated with the proximity of the water bodies to pollution sources such as residential areas, factories, and tributaries. The program's output classified the status of the floating net cages into two conditions: "Stay in position" or "Move." The decision-making application to relocate floating net cages for fish farming in rivers provides a solution for fishermen as the resulting program decisions give the same indication as the reading value of the water quality sensor.

    The Internet of Things (IOT) and Artificial Intelligence (AI) are being increasingly utilized in industrial, household and business sectors expected to change many aspects of the human life. As the nearly infinite possibilities unveil, many people even the expert ones, feel threatened [1, 2]. Calls to manage the risks or restrict the growth of these new trends, make us think about how severely the implications of this growth may change our lives. Human is being surrounded by AI enabled devices which are capable of communicating to each other through IOT. This combination sounds even more threatening than AI or IOT alone. In fact, we are at the edge of believing to be manipulated rather than making use of these newly emerging technologies. This note concerns the role standardization bodies have in this situation. Standards have been widely used to ensure that specific goals (including user safety, environmental compatibility, sustainable development [3], etc.) are fulfilled for a product or service. With IOT and AI appearing in almost any technological product, we have new concerns. Some of the most important of these concerns are listed below [4-6].

    بلاک چین (BC) به دلیل تغییر ناپذیری و مزایای امنیتی و حفظ حریم خصوصی مورد توجه زیادی قرار گرفته است. BC پتانسیل رسیدگی به مسایل امنیتی و حریم خصوصی اینترنت اشیا (IoT) را دارد. از سوی دیگر، BC از نظر محاسباتی گران است، مقیاس پذیری محدودی دارد و هزینه های سربار و تاخیرهای پهنای باند قابل توجهی را متحمل می شود که آن را برای استفاده در اینترنت اشیا نامناسب می کند. در این مطالعه، ما روشی را پیشنهاد می کنیم که BC را برای استفاده در محیط IOT بهینه می کند. ما یک ساختار سلسله مراتبی ارایه می کنیم که از یک BC خصوصی برای افزایش مقیاس پذیری، کاهش سربار شبکه و تاخیر استفاده می کند. در روش پیشنهادی، دستگاه هایی با منابع سطح بالا، شبکه ای به نام شبکه همپوشانی بر روی دستگاه هایی با منابع سطح پایین ایجاد می کنند. اعضای شبکه همپوشانی BC را مدیریت می کنند. چیدمان مدیران بلوک در سطح شبکه همپوشانی دو بعدی است که تمرکز را از مدیریت IOT حذف می کند. ما از تکنیک اعتماد و رای گیری از همسایگان مستقیم برای کاهش ترافیک شبکه و هزینه های سربار استفاده می کنیم. استفاده از عواملی مانند اعتماد، تشویق و جریمه مدیران بلاک در شبکه همپوشانی، تراکنش های دقیق در IOT را تضمین می کند. ما از الگوریتم جدید احراز هویت مدیر بلوک برای احراز هویت در شبکه همپوشانی استفاده می کنیم. نتایج شبیه سازی نشان می دهد که الگوریتم پیشنهادی سربار بسته و تاخیر در ارایه خدمات را کاهش می دهد و مقیاس پذیری BC را در مقایسه با سیستمی که از پایه BC استفاده می کند، افزایش می دهد. علاوه بر این، از آنجا که در الگوریتم پیشنهادی، تعداد مدیران بلوک موثر در رای گیری به همسایگان مستقیم محدود می شود، میانگین زمان تایید یک بلوک به میزان قابل توجهی کاهش می یابد.

    BlockChain (BC) has gotten a lot of interest because of its immutability and accompanying security and privacy benefits. BC has the potential to address the Internet of Things' security and privacy issues (IoT). BC, on the other hand, is computationally expensive, has limited scalability, and incurs significant bandwidth overheads and delays, making it unsuitable for use in the IoT. In this study, we propose a method that optimizes BC for use in IOT environment. we present a hierarchical structure that uses a private BC to increase scalability, reduce network overhead and delay. In the proposed method, devices with high-level resources build a network referred to as the overlay network on devices with low-level resources. The members of the overlay network manage the BC. The arrangement of the block managers at the overlay network level is two-dimensional which removes the focus from IOT management. We use trust technique and voting from direct neighbors to reduce network traffic and overhead costs. The use of factors such as trust, encouragement and penalty of block managers in the overlay network ensures accurate transactions in IOT. We use the new block manager authentication algorithm for authentication in the overlay network. The simulation results show that the proposed algorithm reduces packet overhead and delay in service delivery and increases the scalability of the BC in comparison to the system that uses the base BC. Furthermore, because in the proposed algorithm, the number of effective block managers in voting is limited to direct neighbors, the average time to confirm a block is significantly reduced.

    The internet of things is an emerging paradigm that will change the way we interact with objects and computers in the future. It envisions a global network of devices interacting with each other, over the internet, to perform a useful action. Firstly, we provided the overview of the internet of things and then the relevant technologies that can help in large-scale development of internet of things, then the security issues in internet of things and its challenging. Secondly, we analyzed some of the lightweight authentication protocol in internet of things based on different techniques such as RFID authentication and continuous authentication to evaluate their vulnerability. Finally, we proposed the solution for one of RFID authentication protocol by using physically unclonable functions. In this protocol, the valid authentication time period is proposed to enhance robustness of authentication between internet of things devices and used the authentication token to authenticate the message which transmits from sensor node to the gateway and at the end the security analysis is conducted to evaluate the security strength of the proposed protocol.

    In this paper, the study detects the nutritional deficiencies from these leaves using Internet of Thing (IoT) based image acquisition and nutrition analyser devices. The former captures the color of the leaf and the latter helps in finding the nutrients in each zone based on the image captured by the device. The study uses an improved convolutional neural network to detect automatically the nutrients present in a leaf. The type of leaf is considered from the plants including coriander, tomato, pepper, chili, etc. The Convolutional Neural Network (CNN) is used to extract the patterns of leaf images from the data capturing IoT devices and nutrition analyser device. The system stores and process the data in cloud, where the CNN integrated in Virtual Machines enables the process of input data and process it and sends the report to the authority. A total of 3000 images are collected out of various disorders in five different plants. A 5 fold cross-validation is conducted on training and testing dataset. The system is tested in terms of accuracy, sensitivity, specificity, f-measure, geometric mean and percentage error. The comparison made with existing models shows an improved detection accuracy by CNN than other deep learning models.
