Abstract:- This paper presents a novel method for supporting full interactive video applications over wireless networks. 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 a novel 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. Traditional interactive operations are supported with a minimum of additional resources on the server/network bandwidth and decoder complexity.
