High-speed trains have become one of the most leading transportation means, where each year the manufacture companies reach a new speed record. This progressive speed records increase the handover (HO) rate which makes it very difficult for high speed railway (HSR) mobile communication to sustain a reliable communication link. Utilizing distributed antenna systems (DASs) along with the two-hop architecture, this paper analyzes the conventional handover scheme based on this architecture and proposes a faster HO strategy. The proposed scheme reduces the HO latency and failure probability which could greatly improve the end-users quality of services (QoS). The analytical results show that the proposed scheme performs better than the conventional HO scheme.
