The field of smart agriculture is ranked among the top areas that uses the internet of things (IoT), whose goal is to increase the quantity and quality of agricultural productivity. The aim of this work is to realize a new device that will be cost-effective, reliable, and autonomous using a solar panel to provide electricity in large-scale agricultural fields, ESP32 to interconnect IoT sensors and the long range (LoRa) data transmission protocol to guarantee connectivity in places where there is no internet, whose objective is to monitor and irrigate agricultural fields only when there is a need for water. The data received by the sensors is sent to mobile app users via the Blynk cloud. The performance of our new approach is measured in terms of energy savings. This new model of irrigation and smart monitoring will improve the efficiency of farming techniques.

The internet of things (IoT) connects physical objects through sensors, software, and communication technologies, enabling efficient data collection and sharing. This interconnection promotes automation, real-time monitoring, and improved decision-making across various sectors. In agriculture, the integration of IoT with artificial intelligence (AI) is revolutionizing resource management by providing farmers with real-time information on crop health, climate conditions, and soil quality. This paper explores how IoT and AI are transforming traditional agricultural practices to enhance both efficiency and sustainability. Through an in-depth analysis of existing literature and practical applications in the sector, this study identifies significant advancements in crop management, reduction of losses, and resource optimization. Additionally, it highlights persistent challenges such as data security and interoperability. The aim is to address these challenges and propose innovative solutions to optimize agricultural processes. The results indicate that while IoT and AI offer substantial benefits, further advancements and solutions are needed to fully leverage these technologies for sustainable agricultural development.

The internet of things (IoT) refers to a network of physical devices embedded with sensors, software, and communication tools, which allow for seamless exchange and collection of data. This technology enables automation, continuous monitoring, and data-driven decision-making across a variety of fields. In the healthcare sector, the integration of IoT with artificial intelligence (AI) is transforming how patient care is delivered, providing real-time health monitoring, personalized treatment options, and more efficient management of healthcare resources. This study investigates the significant influence of the IoT and AI on the healthcare system, focusing on how these technologies improve patient outcomes and streamline healthcare operations. It also highlights emerging challenges in the adoption of these technologies and suggests potential solutions to address these obstacles and enhance healthcare delivery.

The growing use of internet of things (IoT) technologies in higher education is transforming how institutions manage infrastructure, deliver teaching, and engage with students. While these advancements offer considerable benefits, they also introduce significant security risks. Common threats include weak access controls, insufficient data protection, outdated software, exposure to denial-of-service (DoS) attacks, and lack of physical safeguards for connected devices. This study provides a comprehensive review of these vulnerabilities within academic environments and proposes a security framework adapted to the specific operational and technical realities of universities. Unlike generic approaches, this research focuses on the unique challenges of higher education, such as decentralized information technology (IT) structures, limited resources, and diverse user groups. The main contribution lies in identifying and evaluating security measures that are both effective and applicable in academic contexts. These include encryption methods, identity verification techniques, secure update mechanisms,and intelligent systems for detecting abnormal behavior. The analysis is supported by case examples from real institutions, illustrating both successes and limitations of current practices. This work aims to guide educational institutions in improving the resilience of their IoT systems. It also outlines areas for future research, particularly in the development of lightweight and scalable security solutions suited to the evolving needs of smart learning environments.

The Capacitated Vehicle Routing Problem plays an important role in supply chain management and logistics, and its optimization helps optimize the logistics of all companies and increase their profits. Since it is difficult to solve, researchers have used several methods to achieve or approach the optimal solution, including exact methods, heuristics, and metaheuristics. The purpose of this article is to investigate the most used techniques, which are metaheuristics, compared to others, and to compare recently implemented algorithms for CVRP. This comparison is based on the collection of algorithm results and the calculation of the Gap for each instance, which can indicate how the solving methods are to the optimal solution. Knowing the most performant metaheuristic in CVRP will empower us to use it in solving other combinatorial problems and to get an idea of how it is designed in comparison with others for performing other powerful metaheuristics.
