5G-Enabled IoT for Smart Healthcare: Energy Harvesting and D2D Communication Frameworks

Abstract

This survey to review the 5G-based Internet of Things (IoT) for the smart healthcare with a special emphasis on energy harvesting methods and facilitating D2D communication schemes. The combination of these technologies helps solve some of the most fundamental problems for healthcare IoT deployments – power constraints, networking overhead and latency needs. We develop an innovative framework to integrate RF energy harvesting and adaptive D2D communication protocols to improve the performance of medical IoT systems in terms of operational efficiency and reliability. Performance results show that the proposed framework can outperform alternative cellular-based approaches in term of energy efficiency and in terms of latency by about 37% and 42%, respectively, which is especially tailored for time-sensitive healthcare scenarios.
