摘要分布式网络化传感器系统在开发边坡灾害监测系统中具有潜在的应用前景。在这种户外应用中，低能耗特性和最终的长运行寿命是一个重要的问题。本文提出了一种概率策略来打开/关闭每个传感器节点，从而减少整个网络的能量消耗。通过数值实验对所提出的概率分配策略的有效性进行了评价，并研究了该策略的收敛性质。
Abstract Distributed networked sensor systems have a potential applicability for developing a slope disaster monitoring system. A low energy consumption property and an eventual long running life are an important issue in this type of outdoor application. This paper proposes a probabilistic strategy to turn on/off each sensor node that could reduce an entire amount of consuming energy over the network. Effectiveness of the proposed probability assignment strategy is evaluated through numerical experiments, and convergence property is also investigated.
