A fast simulation algorithm for molecular dispersion and binding in molecular communications

Abstract

The process of information carrying molecules (IcM) dispersing from a molecular transmitter (MTx) to a molecular receiver (MRx) and the process of these molecules binding to the MRx are two major components of the Molecular Communications (MC). There are many approaches to model these two processes separately. While these models are very efficient when used alone, they suffer from compatibility issues. In this work, we reconcile the models for these two processes in a unified framework. Our proposed framework is influenced by the wave-particle duality of light. We model the dispersion of molecules using the wave model and the interactions using the particle model. We demonstrate our algorithm specifically for the case of synaptic molecular communication (SMC) for a cuboid synaptic cleft, however it can be adapted to any MC system as long as the MTx and MRx exhibit only insignificant positional changes relative to each other.
