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], 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.
Highlights
The history of nanotechnology follows the development of concepts and experimental studies in the broad category of nanotechnology since it was put forward in 1959 (Feynman, 1960)
None have proposed THz channel modeling of Wireless Nanosensor Networks (WNSNs) using electromagnetic waves for producing a universal nanonode working at a specific frequency inside the alveolar spaces and human tissues
The development of nanotechnologies and wireless nanosensor networks will have a major impact in almost all areas of our society, especially in the field of health
Summary
The history of nanotechnology follows the development of concepts and experimental studies in the broad category of nanotechnology since it was put forward in 1959 (Feynman, 1960). Previous publications prove that water has higher attenuation Akkaş et al, 2012 and Yang et al, 2015 as in blood For this reason, in this study, the blood is analyzed which has the minimum capacity, transmission distance and maximum path loss. This work investigates the propagation of electromagnetic waves from 0.01 to 10 THz and proves that the best transmission windows which are ω1 = [0.01 THz – 0.5 THz], 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 0.01 THz – 0.5 THz range 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.
