Amplify-and-forward relaying in mobile multi-hop molecular communication via diffusion Nano. Commun. Netw. (IF 2.9) Pub Date : 2021-08-09 Zhen Cheng, Yuchun Tu, Jun Yan, Yanjing Lei
In this paper, we investigate amplify-and-forward (AF) relaying scheme for mobile three-dimensional (3D) multi-hop molecular communication via diffusion (MCvD) in the stochastic channel by using different type of molecules (DTM) and same type of molecules (STM) in each hop, respectively. Under the DTM scheme, both the inter-symbol interference (ISI) and the noise of each link are taken into account

Localization in power-constrained Terahertz-operating software-defined metamaterials Nano. Commun. Netw. (IF 2.9) Pub Date : 2021-08-03 Filip Lemic, Sergi Abadal, Chong Han, Johann M. Marquez-Barja, Eduard Alarcón, Jeroen Famaey
Software-Defined Metamaterials (SDMs) show a strong potential for advancing the engineered control of electromagnetic waves. As such, they are envisioned to enable a variety of exciting applications, among others in the domains of smart textiles, high-resolution structural monitoring, and sensing in challenging environments. Many of the applications envisage deformations of the SDM structures, such

A fuzzy-logic-based fault detection system for medical Internet of Nano Things Nano. Commun. Netw. (IF 2.9) Pub Date : 2021-07-31 Samane Sharif, Seyed Amin Hosseini Seno, Alireza Rowhanimanesh
In this paper, a fuzzy-logic-based fault detection system is designed for a medical Internet of Nano Things architecture. The goal of this system is to detect the root cause and severity of the faults occurred in the in-body nanonetwork. Since nanomachines have very limited capabilities, the sampled data from the in-body nanonetwork is sent to cloud servers by means of an on-body micro-gateway. The
