部署在铁路沿线的无线传感器网络(wireless sensor network,WSN)用于铁路运行环境监测中,为延长WSN的寿命周期,有必要引入节点休眠机制。因此,首先采用随机过程理论建立了基于节点休眠机制的铁路沿线WSN通信性能分析模型,揭示了铁路沿线不同系统因素对WSN接收性能的影响机理,并得到了最优工作节点比例与其他系统参数之间的关系,搭建仿真平台分别模拟铁路沿线较为安全区域和灾害高发区域的WSN接收性能,最后通过实际案例论证了基于休眠机制的部署方案,可以为铁路沿线WSN的实际部署提供理论指导。
Wireless sensor network (WSN) deployed along the railway can be commonly applied to environmental monitoring.In order to lengthen the lifetime of WSN
it is essential to introduce the node sleeping mechanism.Therefore
firstly the stochastic process theory was adopted and an analytical framework was proposed to study the communication performance of WSN in railway scenarios based on the node sleeping mechanism.Furthermore
the impacts of different system factors on the reception performance of WSN were analyzed under railway scenarios
and then the relation between the optimal ratio of active nodes and other system factors could be obtained.A simulation platform was established to verify the reception performance of WSN in safety areas and hazards-prone sections respectively.Finally
practical case was presented to verify the deployment scheme based on node sleeping mechanism.The analytical results could provide the guidelines for practical deployment of WSN under railway scenarios.
