Probabilistic management of slope disaster detection systems for reduced energy consumption

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 both numerical and hardware experiments.
