Packet Replication and Noise in Reliable End-to-end Molecular Communication

In modern communication systems, noise represents the source of errors that disturb useful information signals for communication. In biological systems, however, noise plays important roles for their functions. In this position paper, we point out that, in designing and engineering molecular communication systems, noise may be removed as in traditional communication systems, while it may be exploited as in biological systems. We first show our prior work on reliable end-to-end molecular communication systems that incorporate packet replication to improve the reliability of molecular communication. We then discuss how the molecular communication systems may be extended based on the observation that biological systems utilize noise for their functions.
