Lígia F. Borges, Michael Taynnan Barros, Michele Nogueira
Abstract
Progress in bioengineering and nanotechnology has led to advances in implantable nanoscale devices. Providing synthetic molecular communication among these devices is an ongoing unsolved challenge. Biological systems inspire promising approaches for engineering data communication in molecular communication, but noises from dynamic tissue signaling result in low data rate and high latency. Thus, error control techniques become critical for reliable communication. This article contributes to a detailed and precise view of existing methods for error control in in-body molecular communication. It classifies the free-diffusion and cell signaling sources of noises. The article presents an error prevention technique, encoding multiple molecular information carriers for cell-signaling-based molecular communication systems. It highlights open research opportunities.
