摘要:
研究节点运动的脉冲耦合无线传感器网络的同步问题，提出一种依赖节点间运动和脉冲调整全网络节点间的耦合结构，实现稀疏节点分布无线传感网络时钟同步的新算法．以Peskin模型确定的相响应函数、网络节点稀疏和低速运动下的数值结果分析表明，节点运动速率、脉冲相响应函数和脉冲强度均对无线传感器网络的同步产生影响．通过分析无线传感器网络中部分节点处于静止时的同步时间问题，得到静止节点数目越多，网络同步速度越慢的结论．
Abstract:
The problem on a pulse-coupled clock synchronization of wireless sensor networks (WSN) with motion nodes is studied in this paper. A novel algorithm is proposed to achieve clock synchronization by adjusting the coupling structure of the network according to the motion and impulses between nodes. The phase response functions determined by the Peskin model, the numerical analysis of sparse nodes and the motion under low velocity have demonstrated that the kinematic velocity of node, impulsive response function and the impulsive strength would affect the synchronization of WSN. The experiments also show that the speed of achieving synchronization decreases when the number of the stationary nodes increases.
