Enabling Adaptive Multimedia over Wireless IP Networks

User demand for multimedia content over the Internet has been rising during recent years. Mobile networks are also increasing, with a trend towards converged voice and data services. This paper looks at the transport of real-time interactive and non-interactive multimedia over heterogeneous mobile networks. Inherent characteristics of mobile networks such as high error-rates and variable bandwidth are challenges for real-time data transport. Techniques such as scalable encoding and synchronisation-event filtering have been proposed as useful methods to overcome these challenges. Research, however, shows that although these methods are useful in order to increase efficiency of transport, there is still work to be done to achieve optimal efficiency.
