Car-to-car communication starting to became important in the attempt to improve road safety. Not only it is able to reduce car accident rate, but also it is useful to minimize traffic jam. The communication media between the cars varied but the low cost solution is to use existing wireless networks such as 3G, Wi-Fi, WiMAX, etc. Car-to-car communication implementation over these existing heterogeneous wireless networks requires a fast and reliable handovers when one network becomes unavailable. This paper presents a study on applicability of using the IEEE 802.21 standard as the handover protocol to expedite vertical handover in a car-to-car communication. A fast and simple car-to-car communication handover scheme is proposed and analyzed to show the effectiveness and how it can be implemented further.
