Studies in Big Data

Internet of things (IoT) based wireless body area network in healthcare moved out from traditional ways including visiting hospitals and consistent supervision. IoT allow some facilities including sensing, processing and communicating with physical and biomedical parameters. It connects the doctors, patients and nurses through smart devices and each entity can roam without any restrictions. Now research is going on to transform the healthcare industry by lowering the costs and increasing the efficiency for better patient care. With powerful algorithms and intelligent systems, it will be available to obtain an unprecedented real-time level, life-critical data that is captured and is analyzed to drive people in advance research, management and critical care. This chapter included in brief overview related to the IoT functionality and its association with the sensing and wireless techniques to implement the required healthcare applications.
