A device-to-device (D2D) assisted cellular network is pervasive to support ubiquitous healthcare applications, since it is expected to bring the significant benefits of improving user throughput, extending the battery life of mobiles, etc. However, D2D and cellular communications in the same network may cause cross-tier interference (CTI) to each other. Also a critical issue of using D2D assisted cellular networks under a healthcare scenario is the electromagnetic interference (EMI) caused by RF transmission, and a high level of EMI may lead to a critical malfunction of medical equipments. In consideration of CTI and EMI, we study the problem of optimizing the energy efficiency (EE) across the mobile users in different priorities (different levels of emergency) within the Internet of vehicles for mobile health, and propose a penalty-function algorithm of power control to solve the aforementioned problem. Numerical results demonstrate that the proposed algorithm can achieve remarkable improvements in terms of EE, while ensuring an allowable level of EMI on medical equipments.
