A novel handover scheme using torch nodes and adaptive measurement aggregation mechanism to improve QoS in high-speed railway communication

摘要

Technological advancement in the field of transportation and communication has been happening at a faster pace in the past few decades.As the demand for high-speed transportation increases,the need for an improved seamless communication system to handle higher data traffic in a highly mobile environment becomes imperative.This paper proposes a novel scheme to enhance the quality of service in high-speed railway (HSR) communication environment using the concept of torch nodes (TNs) and adaptive measurement aggregation (AMA).The system was modeled using an object-oriented discrete event simulator,and the performance was analyzed against the existing single-antenna scheme.The simulation results show that the proposed scheme with its minimal implementation overhead can efficiently perform seamless handover with reduced handover failure and communication interruption probability.
