Modeling and Simulation of a Mobile Molecular Communication System with Frequency-based Directional Sensing

We developed a mobile molecular communication system wherein directional information is encoded through pulse frequency. In this system, a sender bio-nanomachine emits periodic pulses of signal molecules, and these pulses propagate within the environment. The receiver bio-nanomachine determines the direction to the sender bio-nanomachine based on the observed frequency of pulses. A model of the mobile molecular communication system is presented in this article. Subsequently, the model was simulated to investigate the impact of key parameters on system performance including the time required for a receiver bio-nanomachine to reach its corresponding sender bio-nanomachine and the average distance between receiver and sender bio-nanomachines.
