摘要

为了应对5G和物联网技术的进步所带来的无线流量的指数级增长,将使用更高的频段来实现高性能。但这将增强我们周围的相关电磁场(EMF),并可能对所有生物和环境产生有害影响,除非采取必要的预防措施来限制它。在本文中,我们提出了一种优雅的带选择方法,为多跳分组路由提供适当的数据速率,以最小化并平衡传输功率,从而在特定吸收率(SAR)方面对我们产生相关的EMF影响。对线性网络给出了理论分析,得出了给定频带允许跳数的上界。在随机网络上的仿真结果表明,与传统的通过基站的直接通信相比,该技术在SAR方面提高了30 ~ 70%。

Multihop D2D Communication to Minimize and Balance SAR in 5G
To cope with the exponential growth in wireless traffic to be induced by the advancement of 5G and IoT technologies, higher frequency bands will be in use to achieve high performance. But this will enhance the associated electromagnetic field (EMF) around us and may have harmful effects on all living creatures and the environment, unless necesSARy precautionary measures are followed to limit it. In this paper, we propose an elegant method of band selection with appropriate data rate for multi-hop packet routing, to minimize and also to balance the transmission power and hence the associated EMF effect on us in terms of the Specific Absorption Rate (SAR). Theoretical analysis has been presented for linear networks that results an upper bound on the number of hops permitted for a given spectrum band. Simulation results on random networks show that the proposed technique achieves a 30 − 70% improvement in terms of SAR, compared to the conventional direct communication via base station.
