In this paper, the works on time synchronization in wireless sensor networks are investigated step by step. In particular, the diffusion-based algorithms for global synchronization in large-scale distributed sensor network are intensively focused. We thus propose a fast-converged asynchronous diffusion synchronization scheme in order to improve the performance of the asynchronous averaging diffusion method, and then prove its convergence mathematically. The evaluation results and discussions for the proposed scheme are also presented with simulation study. We eventually show that the proposed scheme converges a little faster than the asynchronous averaging diffusion method.
