Human health concerns have often been overseen, while wearable technologies draw erupting interests. Due to direct physical contact with human skin wearable communication devices are mostly known for leading to higher levels of specific absorption rate which is the amount of radio frequency (RF) energy consumed by human tissue in mass units. So far, we have not found any research covering all aspects of wearable technology-i.e., reporting on SAR levels produced from these devices, analytical and experimental contexts that the general public must recognize. This research offers in this context a thorough analysis of SAR from different commercially available wearable devices, as well as the analytical mechanisms and existing methodologies for measuring basic compliance tests. This work is intended to be of interest in educating the general public about the health of the use of wearable devices currently on the market, and in further examining the exact biological effects of electromagnetic field exposure (EMF) due to wearable devices. A major challenge in the implementation of wearable devices is reducing the use of energy. Power management is one of the key energy-saving strategies used in wearable networks. Signals enter the receiver from a transmitter through the human body in the form of EMF radiation produced during the transmission of packet. It may have a negative impact on human health as a result of the SAR. The higher the absorption rate of the body, the more EMF radiation. Therefore, SAR can be reduced by distributing the power over a greater mass or tissue volume equivalently larger. The IEEE 802.15.6-supported multi-hop topology is particularly useful for low-power embedded devices that can reduce consumption of energy by communicating to the receiver through nearby transmitted devices. In this thesis, we suggest a relaying mechanism to minimize the transmitted power and, as a consequence, the power density (PD), a measure of SAR.
