Due to rapid advances in storage, computing, and networking technologies, use of multimedia data has become extremely attractive in diverse applications such as entertainment, education, medical, defense, etc., since it improves visualization, precision, interactivity, and performance. As a result, multimedia data has become one of the leading media type in the Internet traffic. Meanwhile, Internet is becoming increasingly heterogeneous due to the expected integration of cellular networks, wireless LANs, and WANs under the "All-IP" framework. However, most of the cellular and wireless technologies have not been designed to handle multi-user multimedia data traffic. This paper outlines the problems in cellular/wireless technologies for multi-user streaming data traffic (audio, image, video, and graphics) and introduces the approaches to these problems.
