基于半马尔科夫链的中小堤坝WSN节点能耗研究
Research on Node Energy Consumption of WSN in Small and Medium-sized Dams Based on Semi-Markov Chain
摘要
Abstract
The wireless sensor network technology provides a new approach for the small and medium-sized dams' monitoring. Since WSN nodes are battery powered and updating batteries periodically in dam environments is diffi-cult, it's very important to optimize the energy consumption of WSN nodes in order to extend the whole life-cycle of WSN. This paper describes energy consumption distribution and strategies to reduce the energy consumption of WSN nodes. In addition, the algebraic model of the node energy consumption has been set up based on semi-Mar-kov chain theory. In order to ensure the whole network to survive as long as possible, the node sleeping time should be prolonged by managing their energy consumption so that the energy consumption of the whole WSN can be decreased accordingly.关键词
