摘 要: 针对数字航道观测场景变化以及传感器节点能量有限的特点,提出一种将无线传感器网络用于数字航道观测时的自适应休眠调度算法。该算法能感知数字航道观测场景的变化,并据此调整节点的状态。仿真结果表明提出的算法与已有的休眠调度算法对比,更加适应观测场景的变化,从而延长网络生命周期。 Considering the characteristics of varying scenarios in monitoring digital waterway and limited energy of sensors,an adaptive sleep/wakeup scheduling algorithm is proposed for sensor networks applied to digital waterway surveillance.The proposed algorithm can sense the change of digital waterway monitoring scemario and adapt the status of nodes accordingly.Simulation results show that compared with the existing sleep/wakeup scheduling algorithms,the proposed algorithm is more adaptable to the change of monitoring scenarios and can extend the network lifetime.
