Delivery of multimedia digital content through wireless networks poses non-trivial performance issues because of scarcity and volatility of the wireless medium. The goal of this study is to analyze the impact of multipath fading and interference on multicast video streaming in an indoor LOS (Line of Sight) wireless environment using off-the-shelf fixed WiFi equipment. Multipath fading experienced by the receivers is represented by empirically estimating ricean K-factor from packet traces captured at the receivers. Degradation in the video quality incurred during transmission is quantified by measuring video quality metric (VQM). To quantify the impact of channel interference, controlled traffic is generated on a channel adjacent to the selected channel. We use human movements to alter the depth of signal fading at the receivers. Our experiments show that packet loss increased two times in the face of multipath fading and almost three times in the face of channel interference. The measurements presented in this paper can help users to monitor and maintain the quality of their wireless networks and optimize the use of limited network resources.

Wireless Local Area Networks (WLANs) are experiencing higher data rate and radius coverage, making possible high quality audio and video transmission. An IPTV system can be built in any home using the Wireless IEEE 802.11n standard because it provides enough data rate and range than the other IEEE 802.11 variants. IEEE 802.1a/b/g standards do not offer enough bandwidth to provide several ITPV channels to the customers. Moreover, in many cases wireless point to point links are needed to transfer IPTV between faraway places. In this paper, we are going to test the performance of the IPTV over IEEE 802.11n and we will provide the QoS parameters measured in three test benches with up to 17 IPTV customers. Nobody has tested the IPTV performance over IEEE 802.11n until this moment and this work can be used by IPTV service providers in order to know the performance of the IPTV in a wireless access network and in the customer's home wireless network.

“…The authors tested the DirCast system with up to 12 users and concluded that DirCast is well suited for streaming media delivery. The authors of [11] investigate the applicability of the IEEE 802.11b/g/n technologies for multicast-based multimedia streaming. The evaluations are based on the mean opinion score of the evaluators.…”
