Molecular Communications Simulator

Overview

Molecular communications is an emerging paradigm that uses chemical signals for information transfer. Inspired by biological systems (e.g., cellular signaling, pheromone trails), it offers unique advantages in environments where electromagnetic waves are impractical or harmful. This repository provides a modular simulator and supporting tools to design, visualize, and optimize molecular communication systems.

Importance of Molecular Communications

1. Biocompatibility: Uses molecules that naturally occur in biological environments, enabling safe communication within living tissues or microfluidic devices.
2. Energy Efficiency: Chemical signaling can require significantly less energy compared to electromagnetic transmission, critical for nano- and microscale devices.
3. Harsh Environments: Operates in scenarios where radio frequency (RF) is blocked or attenuated (e.g., underwater, underground, inside pipelines).
4. Scalability: Facilitates networks of nanomachines for applications in targeted drug delivery, environmental monitoring, and lab-on-a-chip systems.
5. Novel Applications: Opens new research directions in synthetic biology, nanorobotics, and bio-hybrid systems.
