Humans spend a lot of money on healthcare services. The healthcare business is growing more sophisticated and technologically advanced. It also required patients to expend time, effort, and money to get care. When a patient is in a distant location (particularly for the elderly), it takes time to go to the healthcare facility, make an appointment, and wait for his/her turn to meet with the doctor. Many individuals have perished as a result of heart attacks. If there is technology that can be utilised to remotely monitor a patient's vital signs, it might save lives and offer better treatment. Such QoS is attainable with remote health monitoring using technologies such as cloud computing, sensors, and IoT. When remote health monitoring using IoT technology is realised, particularly for rural people, it will revolutionise the way healthcare services are delivered and ordinary people will survive from a variety of life-threatening illnesses. This paper investigates current IoT-based remote health monitoring systems, as well as their benefits and limits. It also contains a suggestion for a revolutionary remote patient monitoring system that merges PHC in a community with smart beds linked to IoT technology for real-time patient health monitoring. The scope also includes security upgrades to the planned remote health monitoring system, such as support for secure end-to-end connections and the preservation of healthcare data privacy.
