On enhancing the performance of the diffusion-based molecular communication (DMC) networks: Challenges and opportunities

The ultimate aim of the nano molecular communication networks is to change the living organism behaviors (e.g. intelligent drugs “nano actuators”), and to obtain information from living organisms otherwise not accessible (e.g. nano-scale diagnosis for health monitoring “nano sensors”). Utilizing biological mechanism and/or components to transfer information (e.g., molecular diffusion, neuronal networks, and molecular motors) is a new paradigm for nanomachines to exchange information. Diffusion-based communication refers to the transfer of information using molecules as message carriers whose propagation is based on the law of molecular diffusion. In this paper we briefly propose and discuss the Cognitive- DMC network scheme, and concatenated codes for the Diffusion-based molecular communication. Moreover, we discuss some other aspects and challenges that are related to DMC networks.
