چکیده
Abstract—Voice over Internet Protocol (VoIP) may provide good services through Mobile Ad hoc Networks (MANets) platform. It may cover many application scenarios range from safety to comfort related services. However, these networks introduce many challenges for supporting voice with QoS requirements. In this study, we take the first step in addressing the practical issues related to deploying voice call services over MANet. The approach is based on voice streaming between nodes rely on multihop by means of simulation. For this task, a performance evaluation of various voice codecs and its impact on quality of service metrics will be analyzed. Moreover, we study the impact of routing protocol parameter settings on codecs performance. The quality of the voice transmission, using different codecs, is measured and presented in terms of both network and user level metrics. This performance evaluation showed that selecting codec combined with tuning routing parameters, lead to optimal call quality.Voice over Internet Protocol (VoIP) may provide good services through Mobile Ad hoc Networks (MANets) platform.
