LITERATURE REVIEW emergency alert system designed to enhance personal safety by enabling instant communication and real-time location sharing during emergencies. The system utilizes GPS technology for accurate location tracking and GSM communication for automatically transmitting alert messages to pre-registered contacts or emergency authorities. Unlike conventional safety methods that rely on manual reporting, this automated solution ensures faster response by reducing communication delays and human dependency. The proposed system is cost-effective, reliable, and portable, making it suitable for applications such as personal safety, child and elderly monitoring, and organizational security. The system demonstrates the effective application of IoT technologies to provide timely assistance in critical situations.
[1] Sharma and Verma (2022): proposed a smart vehicle accident detection system using vibration sensors along with GPS and GSM technology. The system automatically detects accidents and sends alert messages containing location details to emergency contacts. Their study demonstrated that the low-cost design significantly reduces emergency response time. However, the authors observed occasional false alerts caused by road bumps and sharp vehicle turns, indicating the need for improved detection accuracy. [2] Patel and Singh (2021): developed an IoT-based accident detection and vehicle tracking system integrating GPS and GSM modules with cloud connectivity. The system enables real-time monitoring by uploading accident alerts and vehicle location data to a web server. This approach enhances accessibility for authorities and family members. Nevertheless, the authors highlighted that network dependency remains a major limitation, especially in remote or low-connectivity areas.

1.INTRODUCTION In today’s technology-driven society, safety and security have become critical concerns due to the rising incidence of accidents, medical emergencies, and unforeseen threats. Such situations demand immediate assistance, where delays in communication can result in serious consequences. Conventional safety approaches, including manual phone calls and mobile applications, often fail during emergencies because of panic, stress, or network limitations, emphasizing the need for an automated and reliable alert system.
[3] Khan and Deshmukh (2020): presented an accident detection and notification system using an Arduino microcontroller and GSM module. The system employs an accelerometer sensor to detect sudden changes in vehicle movement. When the predefined threshold is exceeded, an alert SMS with GPS coordinates is sent automatically. The prototype achieved a 95% success rate in location accuracy, though GSM message delays were reported as a concern for real-time emergency response.
Advancements in the Internet of Things (IoT) have enabled intelligent systems capable of real-time monitoring and communication. By integrating IoT with GPS and GSM technologies, compact systems can be developed to automatically transmit accurate location information without complex user interaction. The proposed IoT-based tracking and alert system aims to provide a simple, portable, and dependable safety solution suitable for personal and vehicular applications. Overall, the system contributes to safer and smarter communities by ensuring timely assistance through effective use of IoT and communication technologies.
