A Survey on IoT-Based Healthcare Systems: Innovations, Challenges, and Future Directions

One of the most admirable uses of IoT is in healthcare. Doctors can use the Internet to help people because to IoT. The distance between the patient and the physician can be greatly decreased with portable Internet of Things-based health monitoring equipment. may approach each patient separately, assess their current state of health, and determine the best course of action for them thanks to IoT. Healthcare is fast changing thanks to the Internet of Things (IoT), which promises individualized treatment and eases systemic stress. Devices whispering updates to physicians, tablets reminding patients to take them, and remote monitoring for the elderly are all possible with the development of networked systems. IoT is growing in the developing world because to a number of issues, including a lack of access to healthcare, an increase in chronic illnesses, high healthcare costs, and a growing need for telemedicine. There are suggestions for future research directions along with a presentation of the security, privacy, wearability, and low-power operation challenges that the healthcare IoT faces and conduct a thorough literature assessment of current research on IoT-based healthcare monitoring systems. review. The effectiveness, efficiency, data protection, privacy, security, and monitoring of various systems are compared in the literature study. The report concludes with recommendations and ideas for IoT healthcare applications as well as future directions pertaining to a number of current technological advancements.
