The paper makes three major contributions to this research area. Firstly, one-way information transmission is applied to reduce traffic overhead on Internet for the purpose of clock synchronization. Secondly, the slave nodes use local virtual time and the arrival timestamp, from the reference node, to create linear mathematical trend models and to retrieve the clock precision differences between reference clock and slave clocks. Finally, a fault-tolerant and self-adaptive model executed by each slave node based on the above linear trend model is created in order to ensure that the virtual clock is running normally, even when the link between the reference node and this slave node has crashed. It also presents detailed simulations of this strategy and mathematical analysis on real Internet environments.Read More
