IoT-based smart healthcare system for real-time patient monitoring and care

The Internet of Things (IoT) has revolutionized the healthcare industry by enabling real-time patient monitoring and care. This paper proposes a smart healthcare system using IoT, which integrates wearable sensors, wireless communication technologies, and cloud computing to provide remote patient monitoring and care. The system consists of three layers: (1) perception layer, which collects patient's vital signs using wearable sensors; (2) transmission layer, which transmits the collected data to the cloud using wireless communication technologies; and (3) application layer, which provides real-time patient monitoring and care using cloud-based analytics and machine learning algorithms. The proposed system is evaluated using a case study, which demonstrates its effectiveness in improving patient care and reducing healthcare costs.
