面向极端天气的6G车载卫星切换优化方案
An Optimized 6G Vehicular Satellite Handover Scheme under Extreme Weather Conditions
摘要
Abstract
The rapid development of low Earth orbit satellites and intelligent vehicle technology has driven vehicular satellite communication to become a key component of 6G networks.While intelligent vehicles have advantages in terms of power and antenna deployment,the millimeter-wave frequency band is prone to severe attenuation in extreme weather conditions.Existing handover algorithms are designed for low-speed terminals and lack millimeter-wave link modeling,making them unsuitable for the dynamic environment of vehicular networks.Therefore,this paper proposes a handover scheme that combines signal strength,path loss,and CNR to improve link stability and adaptability.Simulation results show that the proposed scheme increases the service time by 16.9％and throughput by 397.2％under extreme weather conditions,demonstrating its application potential in 6G vehicular communication.关键词
