Abstract
Molecular communication (MC) is an emerging communication method using molecules or particles as signal carriers, which enables nanomachines to send messages at the nano- or micro-nano scale for information exchange and collaboration. Clock synchronization between nanomachines plays an important role in collaboration. The current researches on the synchronization between nanodevices mainly focus on fixed MC systems. However, the movement of nanodevices is widespread in MC systems. A simple but effective scheme for clock synchronization between mobile nanodevices in mobile MC systems based on diffusion is proposed. In an equivalent diffusion mobile MC system model, the number of molecules received by the receiver is related to the transmission time of molecules and the distance between transmitter and receiver at the moment that molecules are released. Based on the detected molecular information, the clock offset and the distance between mobile nanodevices in nanonetworks are estimated by the least-square method. By using different types of molecules, the challenge of the varying synthesis time of the molecule is overcome. The simulation results show the effectiveness of the proposed algorithm.
