Full Interactive MPEG-based Wireless Video Streaming

Despite much research in the field of mobile media, delivery of real time interactive video over noisy wireless channels remains a challenging problem. A major limitation in wireless networks is that mobile users must rely on a battery with a limited supply of energy. Effectively utilizing this energy is a key consideration in the design of wireless networks. In this paper, we jointly consider source coding and dynamic allocation of the physical layer communication resources in an efficient method. The proposed efficient approach achieves acceptable visual quality using minimum transmission energy, while satisfying delay constraints. Mechanism for controlling the interactive streams is also presented and its effectiveness is assessed through extensive simulations. Index Terms Wireless Video, MPEG, Interactive Operations,
