摘要

本文提出了一种分布式传输功率控制（TPC）方案，该方案联合解决隐藏和暴露的终端问题，以提高多跳无线网络的空间重用和公平性能。与之前采用两射线地面反射（TRG）模型的其他发射功率控制方案不同，所提出的方案是基于对数正态阴影（LNS）信道模型设计的。此外，还提出了进一步补偿阴影影响的传输功率选择策略。结果表明，该方案在空间重用和功耗方面优于其他TPC方案，从而提高了吞吐量和能效。

Adaptive Control of IoT Wireless Networks in Shadowed Fading Channels

In this paper, a distributed transmission power control (TPC) scheme that jointly addresses the hidden and exposed terminal problem to enhance the spatial reuse and fairness performance of multi-hop wireless networks is proposed. Unlike other previous transmission power control schemes where the two-ray ground reflection (TRG) model is adopted, the proposed scheme is designed based on a log-normal shadowing (LNS) channel model. In addition, transmission power selection strategies to further compensate the influences of shadowing are presented. Results demonstrate that the proposed scheme outperforms the other TPC schemes in terms of spatial reuse and power consumption, resulting in an improved throughput and energy efficiency.
