  • 摘要: 考慮到在無線傳感器網(wǎng)絡(luò)中，新節(jié)點的加入或老節(jié)點的死亡均會導(dǎo)致拓撲呈動態(tài)變化，該文研究一種完全分布式二階一致性時間同步(Second-Order Consensus Time Synchronization, SOCTS)算法。將節(jié)點的時鐘特性建模成二階狀態(tài)方程，按照偽同步周期廣播節(jié)點的本地虛擬時間，根據(jù)鄰居節(jié)點的本地虛擬時間的不一致來構(gòu)造同步控制輸入；通過坐標變換將網(wǎng)絡(luò)的一致性時間同步問題轉(zhuǎn)化為變換系統(tǒng)的穩(wěn)定性問題，理論分析了SOCTS算法的收斂性和收斂條件，并研究了影響SOCTS算法收斂速度的因素。通過數(shù)值仿真實驗驗證了所提方法的有效性。
    Abstract: Since in wireless sensor networks, the joint of new nodes or the death of old nodes lead to a dynamic topology, this paper studies one completely distributed Second-Order Consensus Time Synchronization (SOCTS) algorithm. The clock feature of each node is modeled into a second order state equation, and the local virtual time is broadcasted according to the pseudo synchronous cycle, Moreover, the synchronization control input is constructed according to the disagreement on local virtual time among neighboring nodes. By virtue of the matrix transformation, the network time synchronization issue is turned into the stability issue of some transformed system, and the convergence and convergence condition for the SOCTS algorithm are analyzed theoretically. Moreover, the factors that influence the convergence rate of the SOCTS algorithm are investigated. Finally, the effectiveness of the proposed method is verified by numerical simulations.
