Abstract

Recently, IPTV services over Internet and wireless networks have been increasing rapidly. Hence, in this paper we introduce a presentation deadline-based cross-layer design for improving the QoS of IPTV services over wireless networks. Our cross-layer design uses the presentation timestamp in the RTP packet header to derive a presentation deadline for each MAC frame. In our design, the wireless Access Point (AP) uses the presentation deadline and the number of retrys to determine whether a MAC frame can be sent or not. Moreover, the MAC fragment size can adapt to the wireless channel conditions. Numerical results demonstrate that the proposed cross-layer design can avoid a waste of wireless channel resources on serving useless MAC frames which will be dropped at the receiver due to missing their presentation deadlines. In addition, the proposed cross-layer design can achieve a lower lateness loss rate and a better application layer goodput for IPTV services.
