Evaluation of Molecular Oscillation for Nanonetworks Based on Quorum Sensing

Bio-inspired molecular communication is a novel kind of communication technology, which uses biochemical molecules as the information carrier. Single nanomachine has limited ability to accomplish targeted goals, so a nanonetwork, which is composed of interconnected nanomachines, is expected. To perform cooperative operations in a nanonetwork, the synchronization among nanomachines is essential. With this purpose, we propose a simple quorum-sensing-based oscillation model. By using the proposed methodology, the instantaneous emission of molecules in quorum sensing is modeled and evaluated. The self-excited oscillation can occur when the molecular concentration decreases below a certain threshold. Analysis and simulations are performed to determine how the biological attributes of the nanomachines, the threshold, the distance between nanomachines and the dimension of the simulation space impact the periods and the phases of the oscillation.
