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。 Aiming at the characteristics of digital channel observation scene change and limited energy of sensor node, an adaptive sleep scheduling algorithm is proposed when wireless sensor network is used for digital channel observation. The algorithm can sense the changes of digital channel observation scene and adjust the state of nodes accordingly. The simulation results show that the proposed algorithm is more compatible with the existing sleep scheduling algorithm and more adapt to the changes of observation scenarios, thus extending the network life cycle.
