Vehicular Ad hoc NETworks (VANETs) is based on 802.11p standard where a vehicle is connected to a base station in a dynamic manner. The vehicle is traversed from one base station to another and may affect the transmission of packets. To minimize the disruption, handoff latency must be kept at minimum duration. This paper presents an improvement of existing handoff mechanism based on vehicle's velocity. The proposed algorithm is called Enhanced Velocity Hand Off (EVHO) where it is defined based on two rules of a mobility model; vehicle speeds and handoff latency. Each rule provides different equations and transforms them into the EVHO algorithm.
