The rapid development of wireless networks has stimulated numerous wireless applications that have been used in wide areas such as commerce, emergency services and entertainment. The number of WiFi capable mobile devices including laptops and handheld devices has been increasing rapidly. As wireless communication gains popularity, significant research has been devoted to supporting real-time transmission with stringent Quality of Service (QoS) requirements for wireless applications. At the same time, a wireless hybrid network that integrates a mobile wireless ad hoc network (MANET) and a wireless infrastructure network has been proven to be a better alternative for the next generation wireless networks. The second algorithm implement to distributed packet scheduling algorithm to further reduce transmission delay, third algorithm implement to a mobility-based segment resizing algorithm that adaptively adjusts segment size according to node mobility in order to reduce transmission time, fourth algorithm implementation to a traffic redundant elimination algorithm to increase the transmission throughput, and last implementation to a data redundancy elimination-based transmission algorithm to eliminate the redundant data to further improve the transmission QoS.
