Fluid Dynamics-Based Distance Estimation Algorithm for Macroscale Molecular Communication [PDF]

Nano Communication Networks, vol. 28, p. 100351, 2021, 2020
Many species, from single-cell bacteria to advanced animals, use molecular communication (MC) to share information with each other via chemical signals. Although MC is mostly studied in microscale, new practical applications emerge in macroscale. It is essential to derive an estimation method for channel parameters such as distance for practical ...
