A Review on Internet of Wearable Things for Pervasive E-Health Care: Energy Efficiency and Prospects

Abstract

Internet of Wearable Things (IoWT) has emerged as a new paradigm of smart computing, especially for tiny, resource-constrained and Internet-enabled ecosystem. With advent of low-cost sensors and open market place such IoWT systems have become inevitably important for monitoring of numerous use cases, for example, health care, tracking, activity recognition and safety assurance. Huge prospects of IoWT simultaneously increase the energy alleviation problem, resulting into facilitation of unstable IoWT ecosystem. Unlimited consumption of energy due to the IoWT implementation can uplift the carbon foot-print. In this article, we present energy efficient approaches for minimizing power alleviation issue in IoWT. Firstly, we present background about the IoWT. We further discuss energy mitigating aspects to make IoWT ecosystem sustainable. Finally, we list a number of key issues and prescribe future direction to improve energy efficient scenario in IoWT.
