Nano-sensor capacity and SNR calculation according to transmit power estimation for body-centric nano-communications

Abstract

This paper presents the capacity and SNR (Signal to Noise Ratio) calculation of nano-sensors propagating model inside the human body. The model based on the calculation of path losses and noise level for THz (Terahertz) wave propagation. In the model the channel capacity and SNR are also studied according to transmit power of nano-sensor for future nano-communications inside the human body. According to the transmit power at frequencies based on the calculation results in blood, skin and fat environments show that at the distance of millimeters, the capacity can reach very high values depending on permitted bandwidth, transmit power and environment. © 2016 IEEE.
