基于无线通信的无缝漫游模型

为了保证列车在高速行驶过程中,与轨旁不同接入点之间进行数据传输的连续性,提出一种利用列车长度特点的无线信号切换模型,通过软件合理调度车头和车尾的信号源,有效避免了新链路的网络连接延迟时间对传输通道的影响,把新链路的网络连接延迟时间压缩为0,实现了列车的无缝漫游。

Seamless Roaming Model Based on Wireless Communication

In order to ensure the continuity of the data transmission between trackside access points during high-speed operation of trains,the paper proposes a wireless signal switching model based on the length of trains.The model can use software to schedule signal sources in the front and rear of a train to effectively avoid the impact of network connecting latency of a new link on the transmission channel,as a result,the network connecting latency of the new link will be compressed into zero,Therefore,the seamles...
