Effects of routing for communication via diffusion system in the multi-node environment

Molecular communication is a pioneering paradigm focusing on the communication between nano- and micro-scale machines, encompassing various novel communication systems. Currently, most of the studies in the literature regarding these systems focus on single transmitter single receiver topologies. However, in a more realistic environment there would be many nodes and the system should be able to handle additional and more complex mechanisms (e.g., routing, scheduling). In this paper, we describe a multi-node environment model for the Communication via Diffusion system and show the benefits of utilizing a routing mechanism in such an environment. The contribution of this paper is twofold: First, the performance of the multi-node environment is evaluated regarding the probability of hit and average propagation delay parameters. Second, we show and evaluate how the system benefits from a routing mechanism by selecting the optimal release point for emitting messenger molecules.
