An anti-outlier robust clock compensated algorithm for wireless network

Abstract

Clock synchronization technology plays an important role in wireless networks, and the improvement of clock synchronization precision has always been the goal pursued by research. This paper introduces a clock compensation technology in wireless networks, which solves two main problems influencing clock accuracy in current clock synchronization technology: time-varying clock frequency deviation and interference from outliers. In this paper, the linear regression algorithm with local weighting and least square sum estimation is used to solve the above problems. Simulation results show that the algorithm has higher clock synchronization accuracy than other algorithms, and the clock synchronization error is significantly lower than the non-robust regression algorithm when there are outliers, proving that this method can effectively resist the influence of outliers on clock synchronization accuracy.
