An implementation of IoT for healthcare

Internet of Things (IoT) is a computing process, where each physical object is equipped with sensors, microcontrollers and transceivers for empowering communication and is built with suitable protocol stacks which help them interacting with each other and communicating with the users. In IoT based healthcare, diverse distributed devices aggregate, analyse and communicate real time medical information to the cloud, thus making it possible to collect, store and analyse the large amount of data in several new forms and activate context based alarms. This novel information acquisition paradigm allows continuous and ubiquitous medical information access from any connected device over the Internet. As each one of the devices used in IoT are limited in battery power, it is optimal to minimise the power consumption to enhance the life of the healthcare system. This work explains the implementation of an IoT based In-hospital healthcare system using ZigBee mesh protocol. The healthcare system implementation can periodically monitor the physiological parameters of the In-hospital patients. Thus, IoT empowered devices simultaneously enhance the quality of care with regular monitoring and reduce the cost of care and actively engage in data collection and analysis of the same.
