• High-speed rail transit systems are becoming one of the major public transportation services connecting many modern cities. The development of automated train control systems plays a crucial role in smart city design and realization. However, the train-to-ground wireless communication network faces challenges due to the high-velocity nature of the railway system, such as the increased probability of handover failures. Research efforts have been made to improve the handover mechanism of LTE-based railway communication protocols, but most solutions are developed and evaluated under the assumption of an ideal linear topology of wireless stations along train lines. In this work, we construct a high-fidelity simulation model based on a real-world measurement dataset. We also implement multiple proposed handover mechanisms and conduct a simulation-based comparative study of them in terms of handover quality and network performance.
