负载依赖的争用窗口控制

Load-Dependent Contention-Window Control

A method for dynamically adjusting the minimum contention window (CW min) in IEEE 802.11 DCF to manage contention in vehicle-to-infrastructure (V2I) networks based on the contending vehicle population. / 一种在车联网中根据争用车辆数量动态调整IEEE 802.11 DCF最小争用窗口(CW min)以管理争用的方法。
