Samenvatting
Fast handover is crucial to provide quality services to mobile users in vehicular environments. WiMAX and WiFi standards support high mobility in vehicular speed. However, WiMAX and WiFi network entry processes may take seconds to complete. This paper presents fast handover approaches between WiMAX and WiFi networks to speed up handover process. Fast Link layer handover protocols are proposed to realize rapid Link layer connectivity. Fast IP layer handover protocols are proposed to achieve high speed IP layer connectivity. The proposed fast handover techniques can be utilized to accomplish the seamless handover in vehicular communication networks.
