| Resumo: | [ANGLÈS] In recent years, the number of mobile and portable devices which are capable to have wireless communications has increased, these mobile nodes connected by wireless link may form a self-configured network to constitute a Mobile Ad-Hoc Network (MANET). Wireless technology has led to development of new communication technology and multimedia services. Due to the continued growth of the mobile users, the demand of multimedia services such as video streaming has increased. Nodes can act as a host or router to forward data from one node to another node in a network which is not reachable by one hop. As they can move freely through the network, it is common to have link breakage, so alternative path should be provided quickly. Furthermore, more stable and reliable paths must be available instead of one path. There are many type of video coding technique for MANET, which one of the best technique used is MPEG-2 VBR that it has a capability of using a proper multipath routing in order to improve distribution of video streams over the paths. Thus for receiving to the best performance using a technique called g-MMDSR (game theoretic- Multipath Multimedia Dynamic Source Routing) in order to select the paths dynamically for sending video by using the game theory approach. The g-MMDSR is an extension of a-MMDSR (adaptive Multimedia Multipath Dynamic Source Routing) technique that includes a game theoretic algorithm in the multipath routing scheme in order to share resources among competing nodes. Our scheme is used to improve the performance of the framework and experience of the end user by sending the most important video frames from one of the two best available paths according to certain probability. In this way we need to examine P value as a fixed and variable to reach the best outcomes, where the number of mobility of the nodes and interfering traffic is too much. This method has designed for MANET network but it capable to use it over the VANET network as well. The result of simulation have demonstrated the benefit of using the game theory technique in different situation over none game theory and also the benefit of variable P value over fixed P value in game theory. |
