Currently, VANETs (Vehicular Ad-hoc Networks) are attracting a lot of interest by the scientific community because of their usefulness in the deployment of more Intelligent Transportation Systems. However, due to the high mobility of vehicles the handover process in this sort of networks represents a serious problem, particularly when vehicles are running real-time applications such as VoIP.

The goal of this work is to enhance the handover management in vehicular networks. To accomplish this goal we propose a solution, which underlies on a pre-registration phase, which will be used to exchange security and QoS (Quality of Service) parameters before the occurrence of the one handover. The proposed solution allows having secure handovers and supports Quality of Service (QoS) for applications with different requirements in VANETs. The obtained results demonstrate that the proposed solution can substantially reduce the number of handovers, improving this way the quality of the service in a VoIP application.
