- ÍtemQos en aodv y aomdv para la transmisión de vídeo h.264/svc en redes ad hoc(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Cuellar Chaparro, Juan Camilo; Petearson Anzola, JohnThis document sets out the approach, process and solution of a research question based on H.264/SVC video streaming in an Ad Hoc network, evaluating QoS in the AODV and AOMDV protocols, under the 802.11 (DCF) and 802.11e (EDCA) standards. The problem posed was in evaluating QoS in the video transmission with the criteria above said, depending on the speed of the network nodes set between 0 and 30 m/s, in such a way that the network studied was of the MANET and VANET type. The study and execution of the proposal was carried out in the simulator of MyEvalSVC research provided by researcher Chic-Heng Ke, This simulator is a set of software (NS2, Python, C++) that allow create and evaluate Ad Hoc network scenarios and packet transmission that is carried out in the network, through the metrics: Delay, Jitter, PDR, Throughput, among others, giving a value of quality of service. Based on the data collected by the MyEvalSVC simulator, it is calculated the values of Delay, Jitter, PDR and Throughput for each network scenario, and With the Matlab tool, the curves of these metrics are plotted in function of the speed of the nodes. From the results of the investigation, it was possible to determine that, when the nodes of the Ad Hoc network move at a speed greater than 10 m/s, the video transmission is of poor quality producing a great loss of packages.
