Handover optimization within vehicular networks

Information exchange and communication among vehicles has become a very interesting problem for vehicular ad hoc network (VANET). Various wireless communication technologies have been proposed for VANET, IEEE802.11p is proposed for short to medium range communication to support the characteristics of vehicular environments. In this environment, the vehicles are characterized by their high mobility which causes frequent interruption of many established connections. However, mobility management is an interesting task for VANET and precisely in an IEEE802.11p which presents the context for this work. In this paper, we will propose a new scheme of the handover algorithm for IEEE802.11p based on the vehicular communications. This handover is based on a communication vehicle-to-infrastructure (V2I). The solution aims to tackle the problems caused by listening to the frame service announcement by the vehicle on the CCH channel, by the anticipation of the entire handover phase before it starts. The performance evaluation and the simulation results show that the proposed scheme can minimize the handover latency and the packet loss.
