中文摘要：
列车在运行时，对轨道和路基等的承载设施进行全面监测并将获取的信息实时传送给机车操控人员和列车运行监控记录装置具有重要的科研和实用意义。以此为背景，本文建立一种多网关移动条件下对线路进行实时监测的无线传感器网络模型，描述网络的结构、定义传感数据生成的服务等级划分规则和数据的传输流程。提出一种在网关运动条件下基于相对位置信息的网络功率控制方法并进行相应的通信协议设计。仿真结果表明，在选择合理的底层通信协议的条件下，该网络能够保证监测数据的可靠传输，并满足节能和实时性要求。
英文摘要：
Comprehensively monitoring the track and roadbed trains are running on and transmitting the corresponding information timely to the locomotive manipulator and the train-running monitoring device are significant to scientific research and practical application. Wireless sensor networks with sink mobility can be used. In this paper, we present a novel wireless sensor network model with multi-sink mobility for real-time track and roadbed monitoring. The network structure is recommended. The patitioned service hierarchy rules for data generation and data transmission process are defined. The dynamic power-control scheme and corresponding communication protocols are designed. Simulation results indicate that this mode is reliable, energy-efficient and of real-time feature.
