摘要
在分析无线传感网络能量消耗特征的基础上,根据无线通信环境和节点的状态转换关系,建立了基于半马尔科夫链的无线传感网络的能耗模型,并通过仿真实验验证得出传感节点实际能耗剩余值与所建模型能耗预估值基本相同,从而说明所建立的能耗模型准确有效,为改变传感节点工作状态、延长传感网络使用寿命提供了可靠的节点能量数据。
This paper analyzes the characteristics of WSN energy consumption. Based on the relationship between the nodes state transformation and the wireless communication environment, a semi-Markov chain model of energy consumption is established. The actual energy consumption remaining value of sensor nodes obtained by simulation is basically the same as the predicted value of the established model, indicating that the model established in this paper is accurately and efficiently providing a reliable energy data, for changing the operating state of sensor node and extending the life of the sensor network nodes.
