Many applications inherited or developed from wired network have been proposed to enable mobile nodes to connect to wireless mobile network to access resources/services from Internet using multicasting protocol. However, wireless mobile networks have difficulty in forwarding information due to its inherent dynamism and frequent topology changes. To multicast multimedia data stream, we have to consider not only the issues of reliability, robustness, scalability and stability of routing protocol, but also the content of transmission. Besides, when handover occurs frequently during transmission, the throughput decreases rapidly due to severe jitter and delay. This thesis presents a hybrid multicasting policy for wireless mobile network to build a multicasting architecture using cross layer design of network layer and application layer to manage quality transmission according to flexible requirements. In summary, our goal is to optimize throughput in order to fulfill the requirement of reliability and stability of multicasting in wireless mobile network.
