  Abstract

In this paper, we present a novel joint application physical-layer design (JAPLD) strategy to cost-effectively transmit linear channels for a portable IPTV service over WiFi-based wireless mesh networks. With this approach, the application layer cooperates with the physical layer to maximize the visual quality. First, in application layer, the standards of wireless network quality for stably transmitting high data-rate streams are first set and inform to mesh environment APs. If the tvFree, a portable IPTV device, moves and the wireless network quality goes out of the preset, the connected AP obtains the wireless network quality between the tvFree and the neighboring AP. If the measured wireless network quality satisfies the previously set conditions, the connected AP guides the tvFree to connect a nearby AP with good quality, though which AP-driven handover (ADH) proceeds in physical layer. Experimental results show that the proposed ADH is able to achieve the performance improvement compared with device-driven handover (DDH) using the IEEE 802.11k standard. Via experimental, we show that the average handover time of ADH is 61% shorter than that of DDH, and thus the received frame rate is higher and the visual quality will be much better.
