## 3 Monitoring and Control Systems Based on IoT
### IoT-Based Monitoring and Control Systems for Transport and Logistics  
In the era of globalization and dynamic technological development, the transport and logistics industry faces increasing challenges related to the efficiency, safety, and sustainable management of supply chains. Enterprises increasingly turn to advanced technologies, including the IoT, to meet these challenges. The IoT in transport and logistics enables the collection, analysis, and exchange of data in real time, which allows for more precise monitoring and control of logistics and transport processes. Implementing IoT systems in this industry brings numerous benefits such as route optimization, monitoring transport conditions, vehicle fleet management and real-time shipment tracking. Thanks to sensors, GPS devices, RFID technology and advanced analytical systems, enterprises can increase operational efficiency, reduce costs and improve service quality. In addition, the IoT helps increase transport safety by monitoring the technical condition of vehicles and road conditions. [PERSON] et al. in [61] proposed an intelligent public communication system based on advanced technology based on a mobile application and the ESP32 microcontroller with a Wi-Fi and GPS module. This microcontroller is installed in each bus, which allows for the real-time monitoring of the vehicle's location and speed. These data are then sent to a cloud server, which is analyzed and made available to users via a mobile application. Within this application, passengers can track the location of buses on Google Maps, find out the estimated arrival time, and calculate the distance to the nearest vehicle. The system operates continuously and automatically: the GPS module in each bus constantly communicates with satellites to obtain current geographical coordinates and speed. These data are then sent via Wi-Fi to the server, processed, and made available in real time to mobile application users. Thanks to this, passengers can quickly and easily obtain the necessary information about the location and arrival time of buses, which allows them to plan their trip better and minimize waiting time at the bus stop. It is worth noting that the proposed system is characterized by ease of use and low costs, making it an attractive solution for public transport users. Additionally, tests on the streets of Mosul confirmed its effectiveness, which showed high accuracy in determining the location and arrival time of buses. The system will be further developed by adding additional functions to the mobile application, such as passenger counting using sensors and introducing an electronic ticketing system using RFID tags. Thanks to continuous development and improvement, the proposed system has the potential to become an indispensable tool for public transport users, providing them with a fast and comfortable journey. The authors of [62] propose a bus tracking system using advanced technologies such as RFID, GPS, and GSM to increase the safety of students' travel between home and college. The problem of long waits at bus stops and the increasing number of crimes against students were mentioned, which makes parents concerned. Therefore, the authors proposed a system to monitor students' travel and notify parents about their safety. The system is based on RFID technology, which is used to identify students through unique RFID cards placed in their backpacks. When a student enters, leaves the bus, or exceeds the speed limit, the system automatically sends notifications to parents via SMS and mobile application. Additionally, the GPS module tracks the bus's location in real time, and the GSM module is used to send notifications. The system consists of three central units: the bus unit, the parent unit, and the college unit. The bus unit has an RFID reader, a GPS module, a GSM module, and a PIC16F877A microcontroller. When a student enters or leaves the bus, the RFID reader records these events, and the GSM module sends notifications to parents.
