This paper proposes a concept of non-orthogonal multiple access (NOMA) for diffusion-based molecular communication (DBMC) networks. The method relies on the difference in received signal levels for multiple access and uses successive interference cancellation. We analytically investigate the bit error probability (BEP) of a communication system using NOMA with two transmitters (TXs) and a central receiver. Initial results show that the BEP can be minimized by balancing a high received signal level from each TX with the separation in received signal level between the TXs. The identification of this trade-off is a first step towards the further analysis of NOMA for single-molecule-type multiple access in future DBMC networks.     «
