Towards Mastering Complex Particle Movement and Tracking in Molecular Communication Simulation

Simulation of molecular communication requires rather application-specific channel models for the physical layer, i.e., the movement of molecules in a target environment. There is already a number of simulators available that apply different concepts for this task. We compare them in terms of geometry of the environment, molecular movement and tracking, as well as visual representation. We identified particle movement and tracking as one of the most challenging research questions in this domain. As a possible solution, we suggest the use of vector fields, which are also used in fluid mechanics, to simulate more complex molecular communication channels.
