VOIP Applications Over Manet: Codec Performance Enhancement by Tuning Routing Protocol Parameters
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 paper, the authors 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 multi-hop 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, they study the impact of routing protocol parameter settings on codecs performance.
