Adjusting Frame Duration Mechanism of NEO Based on Two-sided Hypothesis Test

This paper uses two-sided hypothesis test to check the change of update arriving interval and computes the adjusting value of frame duration accurately according to current network condition,so that the deficiency of original NEO protocol's simple comparing and imprecise adjusting is improved.The voting right is delivered to game engine to avoid forcing players to vote.Simulation results show that the improved frame duration can be adjusted to adapt to network condition steadily which is closer to real network condition,and the protocol performance is enhanced to some extent.
