摘要
针对现有剩余能量的监测算法对节点进行全局监测,并不具有针对性,使得参与通信的节点数较多,资源浪费,提出了一种改进的剩余能量边界监测方法,此算法通过为节点配备代理节点,采用阈值检测方法,只得到剩余能量值处于用户感兴趣范围内的节点区域边界,相比较全局监测减少了参与通信的节点数。另外,通过多个方向的同时监测,提高了监测的可靠性。实验仿真表明,此算法能够有效得到事件边界,并限制参与通信的节点数,降低了能耗。
Due to the existing residual energy monitoring algorithms are most of global monitoring, it is not tar- geted, makes the number of nodes participant in communication is more and waste of resources. An improved boundary monitoring algorithm for residual energy is proposed, each node is equipped with an agent node, with the method of threshold detection to achieve the boundary that is valuable to the user. Energy consumption is limited compared to the global monitoring, because it limits the number of nodes participate in the communication. With Multi-direction monitoring, the reliability improves. Simulation experiment shows that this algorithm can effectively get event boundary and reduce the energy consumption.
