Abstract: The collaborative operation of nodes in distributed systems requires stable node information synchronization as a guarantee. Unlike the relatively ideal communication conditions in research fields such as distributed storage, distributed systems deployed on mobile platforms face stability challenges in information synchronization due to non-ideal communication conditions. Aiming to improve the stability of information synchronization in distributed systems under non-ideal communication conditions, this study designs a redundant information transmission scheme and an information synchronization method based on a weak consistency criterion. Simulation results demonstrate that the proposed method can enhance the stability of information synchronization in distributed systems under non-ideal communication conditions, at the cost of a certain reduction in data transmission efficiency.
