摘要：With the rapid development of mobile communication and the proliferation of mobile terminals, multimedia mobile business (MMB) is proposed and becomes a hot point of the research. 4G networks where the bandwidth won't be the transmission bottleneck will provide powerful support to MMB. As an important part of 4G, MANET is not capable of providing MMB because of the varying wireless channels, so we focus on MANET to provide robust MMB. In this paper, we proposed solutions to solve the problems in MMB. In order to improve the tolerance of the multimedia stream, we design a robust coding method and employ adaptive FEC to add minimum redundant information while achieving highest perceived quality. We extend AOMDV protocol to find a path with lowest delay and highest reliability, and joint priority scheduler to provide optimal transmission scheme. We also take security into consideration when providing MMB in 4G. © 2009 IEEE.
