Terahertz communication inside the human body uses minimal power; therefore, the destination may not receive the signal properly due to losses caused by molecular absorption and path loss. In this paper, we developed a new cooperative communication for the Internet of Nano Health Things (IoNHT), named the Best Path Selection in IoNHT (BPS-IoNHT). In addition, an innovative communication scenario for Nano Body Sensors Networks (NBSN) has been proposed. The proposed protocol has been thoroughly analysed and mathematically formulated regarding path loss, outage probability and bandwidth efficiency. The objective of the work is to reduce the outage probability and increase bandwidth efficiency. The results show that the proposed protocol performs better than recently published work. The outage probability has been reduced by 29%, and bandwidth efficiency improved by 35% compared to recent work.

人体内的太赫兹通信使用最小的功率；因此，由于分子吸收和路径损耗造成的损失，目的地可能无法正确接收信号。在本文中，我们为纳米健康物联网 (IoNHT) 开发了一种新的协作通信，称为 IoNHT 中的最佳路径选择 (BPS-IoNHT)。此外，还提出了纳米体传感器网络 (NBSN) 的创新通信方案。所提出的协议已就路径损耗、中断概率和带宽效率进行了彻底分析和数学公式化。这项工作的目标是降低中断概率并提高带宽效率。结果表明，所提出的协议比最近发表的工作表现更好。中断概率降低了 29%，
