移动式脉冲耦合振荡器实现动态WSN时间同步
Realization of Time Synchronization in Dynamic WSN by Mobile Pulse-Couple Oscillator
摘要
Abstract
Specific to the wide application of mobile sensor in wireless sensor network(WSN),this paper proposes applying a mobile pulse-couple oscillators(MPCOs)model into the two-dimension dynamic WSN with interactive in⁃terfaces to obtain a method for time synchronization in dynamic WSN so that restrictions from factors including mo⁃tion direction,speed and communication distance on traditional time synchronization models can be relieved. To im⁃prove the convergence speed of time synchronization,this paper analyzes the effects of sensor node quantity,cou⁃pling strength,speed and communication radius on the convergence speed of the proposed time synchronization method and concludes that convergence speed is positively proportional to sensor node quantity,coupling strength, speed and communication radius. The shortest convergence time for synchronization is realized by optimizing the network through the optimal parameters and energy consumption and information loss are accordingly reduced. Ef⁃fectiveness of the proposed method is testified through numerical simulation.关键词
