摘要 针对部署环境复杂多变的海洋传感器网络,根据不同海洋参数对水声通信的影响,设计海洋参数自适应时间同步(OPA-Sync,ocean parameter adaptive time synchronization)算法。通过参数调节来提高时间同步算法对不同海洋环境的适应性,并对算法进行了优化,提高运算效率。仿真表明,OPA-Sync可以适应不同的海洋条件,在同步精度和能效方面都优于现有算法。 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.
