Abstract

Intrabody communication using Electromagnetic (EM) waves in Terahertz (THz) band improves the scope of Intrabody nanonetworks (Intra-BNNs) for a wide range of applications such as continuous cellular level monitoring, disease diagnosis, and treatment. The emerging potential of EM-based communication is primarily challenged by molecular absorption noise and channel modeling in the THz band, which require serious consideration. The presented work primarily focuses on the thermal impact of molecular absorption noise on the biological medium during data routing decisions. In this work, we propose a Simulated Annealing (SA) algorithm based routing scheme that ensures the optimal global selection of Nano Bio Sensors (NBSs) for data reporting to avoid hotspot formation and temperature rise. The obtained results confirms that proposed SA algorithm-based routing scheme outperforms the state-of-the-art schemes with the minimal complexity.
