论文摘要
关于可穿戴通信的主要问题是在暴露于可穿戴设备产生的射频辐射（RF）辐射下的人类生物学安全。实施可穿戴设备的最大挑战是减少能源的使用，以最大程度地减少暴露于RF对人类健康的有害影响。电源管理是可穿戴网络中使用的关键节能策略之一。信号从发射机（TX）通过人体进入接收器（RX），以在数据包传输过程中产生的电磁场（EMF）辐射的形式。由于特定的吸收率（SAR），它可能对人类健康产生负面影响。 SAR是人体组织中质量单位消耗的射频能量的量。人体的吸收率越高，射频辐射越多。因此，可以通过在较大的质量或组织体积上分配功率来减少SAR。电气和电子工程师研究所（IEEE）802.15.6支持的多跳拓扑对于低功耗嵌入式设备特别有用，这些设备可以通过附近的传输设备通过与接收器（RX）通信来减少能源的消耗。在本文中，我们提出了一种传递机制，以最大程度地减少发射功率，并因此，功率密度（PD），是SAR的度量。
A major concern regarding wearable communications is human biological safety under exposure to radio frequency (RF) radiation generated by wearable devices. The biggest challenge in the implementation of wearable devices is to reduce the usage of energy to minimize the harmful impacts of exposure to RF on human health. Power management is one of the key energy-saving strategies used in wearable networks. Signals enter the receiver (Rx) from a transmitter (Tx) through the human body in the form of electromagnetic field (EMF) radiation produced during the transmission of the packet. It may have a negative effect on human health as a result of specific absorption rate (SAR). SAR is the amount of radio frequency energy consumed by human tissue in mass units. The higher the body's absorption rate, the more radio frequency radiation. Therefore, SAR can be reduced by distributing the power over a greater mass or tissue volume equivalently larger. The Institute of Electrical and Electronics Engineers (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 (Rx) through nearby transmitted devices. In this paper, we suggest a relaying mechanism to minimize the transmitted power and, as a consequence, the power density (PD), a measure of SAR.
