摘要 以不同的扫描时间间隔和车载移动速度,对车载移动环境下AP间切换误判性能进行了系列的仿真和实验研究.结果表明,在快速移动环境下,通过合理设置扫描间隔,基于多无线模块的AP间快速切换方法能保证较低的AP间切换误判率,可以满足车载Wi-Fi应用的切换判决需求. At different scan intervals and moving speeds, simulation and experimental studies have been carried out for the misjudgment performance of inter AP handoff for on-board Wi-Fi applications. The results show that, in a fast-moving environment, if the scan interval is reasonable, the misjudgment rate of inte-AP handoff is low, whieh can meet the requirements for handoff judgment of on-board Wi-Fi applications.
