Molecular Communication: Exploring the Potential of Nanoscale Information Transmission

Realizing molecular communication (MC) transmission at the nanoscale is currently a research hotspot in the international communication field. It uses the interaction between information molecules and their ability to transmit information to construct nanonetworks for communication. In this study, we present the definition of MC as well as its relevant characteristics and main applications. A comparison with traditional communication is provided, followed by an exposition of the system components. The channel modeling and modulation encoding techniques are summarized. Finally, the research challenges that MC may face are discussed, laying the groundwork for future development.
