Abstract

Abstract:

An ocean parameter adaptive time synchronization (OPA-Sync) algorithm was proposed,which based on the influence of ocean parameters in different conditions.It improved the adaptation of time synchronization algorithm by adjusting the ocean parameters in the complex and varied environment.And the algorithm was optimized to improve the operation efficiency.Simulation results show that OPA-Sync can be adapted to different ocean environments,which is better than other existing time synchronization algorithms on the synchronization precision and efficiency.

Key words: sensor network, ocean parameter, adaptive, time synchronization
