Abstract
Unlike many other Internet of Things applications, in addition to the limited power of Internet of Medical Things devices, the safety aspect and reliability are the major concerns while designing wireless body area network routing solutions. In fact, the heat dissipation from Internet of Medical Things devices and changes in body posture cause tissue damage and frequent wireless links breakage, respectively. Hence, designing an efficient routing solution is extremely challenging in wireless body area network. Considering the safety aspects of human body, the power constraint of Internet of Medical Things devices, and topological variations in wireless body area network environment, this article presents a thermal-aware, energy-efficient, and reliable routing protocol named thermal and energy aware routing. In the given perspective, thermal and energy aware routing considers the weighted average of three costs while selecting the routing path: energy consumption, heat dissipation, and link quality (between communicating nodes). The proposed protocol is validated by a comparison with a state-of-the-art wireless body area network routing protocol. Simulation results demonstrate that the proposed protocol is efficient in terms of energy consumption, thermal impact, and packet reception rate.

Contemporary health care systems are dealing with demanding situations due to the rapid growth of the aged population and restricted monetary resources
The overall financial resources spent in the United States for health care were US$1.8 trillion in 2004, and this figure is predicted to be tripled by 2020.1 These are the alarming statistics, which attract the researchers across the globe to improve the quality of life and to make innovations in health care sector
The extensive simulations are conducted in MATLAB 2017 to analyze the transmission power level (TPL), received signal strength indicator (RSSI), and the relationship of RSSI with packet reception rate (PRR)
Summary
Contemporary health care systems are dealing with demanding situations due to the rapid growth of the aged population and restricted monetary resources. The overall financial resources spent in the United States for health care were US$1.8 trillion in 2004, and this figure is predicted to be tripled by 2020.1 These are the alarming statistics, which attract the researchers across the globe to improve the quality of life and to make innovations in health care sector. A wireless body area network (WBAN) consists of many miniature Internet of Medical Things (IoMT) devices which are either implanted inside a human body or wearable to take critical body readings like heartbeat, body temperature, blood pressure, sugar level, muscular motion, and many more. These readings are communicated to the respective doctors and health monitors to take timely necessary actions. This results in improved quality of life by taking decisions on lifethreatening parameters without wasting time
