Voice over Internet Protocol (VoIP) may provide good services through Vehicular Ad-hoc NETworks (VANETs) platform by providing services to many application scenarios range from safety to comfort. However, VANETs networks introduce many challenges for supporting voice with QoS requirements. In this paper, the authors' study is based on inter-vehicle voice streaming rely on multi-hop fashion. For this task, a performance evaluation of various audio CODECs will be analyzed by mean of simulations. Furthermore, they test the impact of network environment on QoS metrics.
