The paper presents a novel smart blood bank management system leveraging GPS technology to mitigate the challenges posed by blood scarcity and inefficient blood donation practices. The system employs location-based services to establish real-time connections between blood donors and seekers, enabling a more streamlined and time-sensitive blood supply. The system's architecture comprises a geolocation-based blood donor application and a centralized database. The application facilitates donor registration, profile updates, and targeted donor searches based on specific blood requirements and geographical proximity. The centralized database maintains real-time information on blood inventory, donor profiles, and blood donation requests. To optimize donor identification, the system integrates GPS and nearest neighbor algorithms to pinpoint the most suitable donors based on the user's location and blood type requirements. This location-aware approach enhances search efficiency and ensures the timely availability of blood when needed. The proposed system aims to transform blood bank management by fostering a more efficient, transparent, and reliable blood donation process, ultimately contributing to lifesaving interventions
