The Internet of Things: an introduction The Auto-ID laboratory at MIT (Massachusetts Institute of Technology), in 1999, first proposed the concept of the Internet of Things. The main idea of ​​the Internet of Things is to connect all objects to the Internet through sensor devices such as RFID (Radio Frequency Identification) to realize intelligent recognition and network management. The main supporting technology of the Internet of Things is a wireless sensor network and radio frequency identification technology. The International Telecommunication Union (ITU) in Tunisia released a report on the World Summit on the Information Society (WSIS) on November 17, 2005. which addressed the concept of the Internet of Things. In the 2005 ITU Internet of Things report, then published, it stated that everything can be connected to each other at any time and in any place using wireless sensor network technology, radio frequency identification technology, integrated technology intelligent and nanotechnology. From a technical point of view, the Internet of Things can be defined as a network that can realize the interconnection of all things anytime, anywhere with accurate control, reliable transmission, comprehensive awareness and intelligent processing using supporting technologies, such as wireless sensor network technology, microsensors, intelligent integrated technologies, RFID, integrated intelligent processing technology, Internet technologies and nanotechnology. Understanding IoT: IoT-based healthcare systems work on the basic definition of IoT, which is a network of devices that can be directly connected to each other to capture data and share vital data using a secure service layer (SSL) connected at one center... at the center of the paper... data analyzed using wireless technology with medical professionals for their review and recommendations. This system will help improve healthcare services through accurate diagnosis, early detection of acute complications, and accurate and timely administration of medications to patients. The data collected will also help take a preventative approach by allowing people to make healthier choices, thus improving their quality of life. The figure below shows how remote patient monitoring can be performed using IoT. Early Intervention/Prevention: An IoT-based healthcare application will help in daily monitoring of health parameters and alert family members and regularly consult the doctor in case major changes in health parameters are noticed. This will help in providing timely healthcare service to the patient without wasting much time.
