Time synchronization provides uniform timescale for distributed sensor networks.In this paper a genetic based time synchronization optimize algorithm is proposed.It first generated the nondeterministic transmitting delay and then adopted the genetic algorithm to simulating these delays.Minimal linear fit residual error is selected as fitness function to evaluate the simulating effect.After finding the best fitness delay sequence, the time skew and offset is estimated by linear regression.The experiment result shows that the synchronization precision could be improved from 11.8 s to 3.5 s .
