In this paper, Internet of Things (IoT) based healthcare monitoring system is studied. Several number of sensors are used to extract data of various health parameters of a patient, which is then reserved into the cloud. The data stored in cloud can be further displayed through website. The performance of a healthcare monitoring system is investigated where a short message service (SMS) notification helps a patient to remember the timing of medication and create an optimum surrounding as per the patient's condition. Under any emergency condition, the system also generates list of nearby doctors using their geographical coordinates, which is given by GPS module. The closest doctor is then located by comparing the distance of each doctor from the patient using a distance algorithm. © 2019 IEEE.
