Adaptive re-transmission scheme for wireless mobile networking and computing

Due to the growing popularity of smart phones, video streaming on wireless network has increasingly become a pivotal application for customers. Comparing with wired network, packet loss and transmission delay are two of the major hurdles to achieve a friendly user experience. In this paper, we propose an adaptive re-transmission scheme in the radio layer based on the priority of each frame, which gives a good balance between video quality and delay without overhead of involvement from upper layers (application layer / tcp layer). Testing shows a good overall user experience is achieved in terms of video quality and delay.
