Abstract :
There are a lot of handovers failed in high-speed mobile environment because the handover can´t be completed in time although the field strength values are sufficient availability along the tracks. A mobile relay based fast handover scheme is proposed which is suitable for high-speed mobile environment. Two reference points are introduced to ensure handover in time. Pre-preparation and packet bi-casting is introduced to reduce communication interruption time and realize seamless handover. The performance of the proposed scheme is analyzed in terms of handover delay, communication interruption time and bi-casting time.
