城轨列车无线传感器监测网络节能设计

Design of Energy-saving Strategies for Urban Railway Wireless Sensor Monitoring Networks

近几十年城市人群的主要出行方式逐渐转变为轨道交通,而确保列车处于高效而安全工作状态则是重中之重。延长列车无线传感器监测网络生命周期并降低其能耗可以更好地保证列车安全问题。论文主要从单一节点、MAC协议、路由协议三个层次上对整个监测网络进行节能设计,达到合理分配能耗进而最大程度延长监测网络生命周期的目的。

In recent years rail transport has become the main way to travel,so it is extreme important that the safety,efficient and reliable operation of train which for the whole public traffic network and the development of the city should be guaranteed.Reducing energy consumption of sensor monitoring network and extending the train monitoring wireless sensor network life cycle is the core to guarantee the normal work of the train monitoring network.This paper is mainly from a single node,MAC protocol,routing protocol on the three aspects of the entire monitoring network for energy saving design to achieve purpose of a reasonable distribution of energy consumption and maximum extent of the monitoring network to extend the life cycle.
