摘　　要：依据无线传感器网络(WSNs)的串音与碰撞退避机制(CCAM),提出了基于最大度节点(MDN)与其所有的邻居节点保持相同休眠-唤醒机制的通讯方式(SSAM).在SSAR的通讯方式下,文中给出了相应的控制律.在该控制律下,得到了在多变化时滞和噪声环境中基于马尔可夫切换的系统.P-阶矩指数稳定性理论表明,所得的系统与目标函数保持同步。Based on the conflict and crosstalk avoidance mechanism（CCAM）,the paper proposed a sleeping-awaking method for wireless sensor networks（WSNs） in which the maximal degree node（MDN） and all its neighbor nodes run sleep or wake mechanism simultaneously.The method was said to be the same sleeping-awaking method（SSAM）.Under such topology,the related control law about SSAR was provided accordingly.In the light of the designed control law,it got a Markovian switching system with both white noise and multiple time-varying delays.Based on the theory of exponent stable in P-th moment,it shows that the control law ensures the system to keep synchronization with the target function.
