Abstract

Molecular communication (MC) is a promising paradigm which utilizes molecules to implement communication among nanomachines. Due to short transmit range, decode-and-forward (DF) relay is used to extend the communication distance and achieve reliable remote communications in diffusion-based MC systems, in which the distribution of the number of molecules received at the reception node is modeled as an approximate normal distribution. The impact of DF relay position and the reception radius on the system performance are exploited, and the minimum error detection criterion is used to detect the signal. Our simulation experiments show how the parameters in the model affect the performance of the MC relay system based on diffusion, which can guide us how to improve the performance of the system in the future.
