摘要
切换是高速铁路通信服务质量的关键。随着高速铁路运行速度的提高,列车的交接也越来越频繁。然而,GSM-R的硬移交将使通信业务在短时间内中断。为了减少切换延迟,我们提出了命名数据网络-铁路(NDN-R)中的快速切换机制(FHM)。命名日期网络(Named Date Networking, NDN)是面向内容的,FHM在交换发生后不需要建立端到端连接。因此,FHM可以在不中断通信业务的情况下快速切换到下一跳节点。此外,FHM可以避免乒乓切换,进一步提高通信质量。仿真结果表明,与传统的切换机制相比,FHM可以将切换延迟降低72%左右。可以降低丢包率和平均时延,提高吞吐量。
Handover is crucial for quality of communication service in high-speed railway. With the speed increases, the handover becomes more frequent in high-speed railway. However, the hard handover of GSM-R will break down the communication service for a short time. To reduce the handover latency, we propose the Fast Handover Mechanism (FHM) in Named Data Networking-Railway (NDN-R). Named Date Networking (NDN) is content oriented, FHM does not need to establish an end-to-end connection after the handover occurs. Therefore, FHM can fast handover to the next-hop node without interrupt the communication service. In addition, the FHM can avoid the ping-pong handover which further improves the quality of communication. Simulation results show that the FHM can reduce about 72% of the handover latency compared to the traditional handover mechanism. The packet loss rate, average delay can be reduced and the throughput can be improved.
