Energy-Efficient Remote Healthcare Monitoring Using IoT: A Review of Trends and Challenges

Abstract

The emergence of Internet and technologies such as Wireless Sensor Network (WSN) has created another platform of Wireless Body Area Network (WBAN) and also an ever growing new area of Internet of Thing (IoT). A WBAN offers a flexibility and mobility to health monitoring system. Most of WBAN is made up of several small and light-weighted battery-operated sensor nodes and lead to energy-constrained system. Thus, an energy-efficient WBAN system is crucially needed to make the network last longer. In addition, data reliability and data transmission is important to make the system more effective. IoT concept helps in forming an interaction of things in the surrounding as well as support data storage (database) for collected vital body sign by the sensors. In this paper, we review the concept and design of energy-efficient WBAN and contribution of IoT in healthcare monitoring system.
