NUMERICAL ANALYSIS OF THE ALVEOLAR SPACES AND HUMAN TISSUES FOR NANOSCALE BODY-CENTRIC WIRELESS NETWORKS

Abstract

This paper investigates the propagation of Terahertz (THz) electromagnetic waves inside the human body and discusses a model of the system performance of Nanoscale Body-Centric Wireless Networks inside the alveolar spaces and human tissues. THz band wireless communication enables new applications especially in nanoscale wireless communication. The model developed in this paper calculates the total absorption loss, path loss and capacity properties of EM waves propagating through the Alveolar Spaces and Human Tissues in nanoscale environment for THz band wireless communication. Based on the modeling of noise level and path losses, the channel capacity is calculated. The results show that Wireless Nanosensor Networks (WNSNs) can communicate through the human body. According to the numerical analysis of the model several transmission windows which are ω1 = [0.01 THz – 0.5 THz],\xa0 ω2 = [0.58 THz – 0.74 THz] and ω3 = [0.77 THz – 0.96 THz] have been found for Nanoscale Body-Centric Wireless Networks. The longest and lowest transmission window which is in the range of 0.01 THz – 0.5 THz values have been analyzed for blood, plasma, RCBs and water to design universal nanonode for Nanoscale Body-Centric Wireless Networks at gases in lungs and blood.
