I. Introduction
IoT, as a network of interconnected things, plays a pivotal role in connection between physical world and cyberspace. It allows people and things to be connected with anything, with any network use, from anywhere, and time and anyone to transmit information and data. Everything in the physical world is becoming connected with others globally due to use of internet. All these advantages are guaranteed by the increasingly powerful IoT smart sensors with capabilities of data collection, transmission, processing and storage. With these “smart” features, IoT also brings a new revolution to healthcare industry. For example, the IoT can assist the existing healthcare system by developing flexible remote Patient Monitoring System (PMS) that can benefit the patients by continuous collecting physical data (such as heart rate, blood pressure and body temperature) and getting quick medical responses from the medical practitioners. Figure 1 gives a schematic of an IoT based PMS, in which a smart phone performs as the sink device aggregating the physical data and transmitting the data to the practitioner for the best decision and further treatments.
