An Effective Distance Measurement Method for Molecular Communication Systems

Abstract

Molecular communication is a promising communication paradigm for the applications of biomedical engineering, nano-material manufacturing, etc., at nano- to microscale. Measuring distance between nanomachines is critical for adaptive communication design or location-based functionalities. In this paper a novel effective distance estimation method is proposed. Two types of molecules are released by the transmitter nanomachine. Due to the different diffusivity of the different types of molecules, the receiver can estimate the distance. Synchronization between the transmitter and the receiver is not required. The simulation results demonstrate that the proposed scheme has a good performance in terms of accuracy and anti-noise ability.
