“…Nearly all of the solutions to improve multicast services rely either on integrating automatic repeat request (ARQ) mechanisms into the protocol architecture [10]- [14], or adding FEC to the multicast stream [15], [16], or both [17]. Other studies propose rate adaptation mechanisms for improving network utilization [18].…”

IEEE 802.11-based wireless local area networks, referred to as WiFi, have been globally deployed and the vast majority of the mobile devices are currently WiFi-enabled. While WiFi has been proposed for multimedia content distribution, its lack of adequate support for multicast services hinders its ability to provide multimedia content distribution to a large number of devices. In earlier work, we proposed a dynamic scheme called AMuSe that selects a subset of the multicast receivers as feedback nodes. The feedback nodes periodically send information about channel quality to the multicast sender and the sender in turn can optimize multicast service quality, e.g., by dynamically adjusting transmission bit-rate. In this paper, we discuss several experimental results for the performance evaluation of AMuSe. Our experiments use more than 250 nodes placed in a grid topology in the ORBIT testbed. We consider different experimental scenarios: with and without the presence of external noise. Our focus is on studying the performance of WiFi nodes in WiFi multicast and establishing the conditions that make AMuSe an attractive scheme for feedback in WiFi multicast.

“…A higher sustainable transmission rate requires stronger FEC while a lower transmission rate has lower PER, so a weaker FEC. Therefore, unlike conventional multicast where transmission rate and FEC rate are fixed, we also consider a rate adaptive direct transmission mode as in [8], where the transmission rate and FEC rate are dynamically adjusted to improve the video rate. For cooperative multicast, we also optimize the video quality over different transmission rates and the corresponding FEC rates.…”

“…In particular, adaptation of the FEC rate enables transmission at higher rates at both hops, thereby improving the video quality. We evaluate the performance of the proposed system and compare with rate adaptive direct transmission [8] and conventional multicast. We further consider layered coding to provide better video quality to nodes with better channel conditions.…”

In this paper we study a two-hop cooperative transmission scheme where multiple relays forward the data simultaneously using Randomized Distributed Space Time Codes (R-DSTC). We propose to integrate this randomized cooperative transmission with layered video coding and packet level Forward Error Correction (FEC) to enable error resilient video multicast. Data rates in both hops as well as the FEC rate are adopted to maximize the video quality. Our results show that while rate-adaptive direct transmission provides better video quality than conventional multicast, randomized cooperative scheme outperforms both strategies significantly.

“…A large variety of rate adaptation schemes have been presented in the literatures [2][3][4][5][6]. However, most of them are designed for unicast, such as ARF (Automatic Rate Fallback) [2] and SampleRate [6], which implement a simple open-loop rate adaptation scheme (i.e., without feedback from the receivers) due to their simplicity.…”

Wireless video multicasting/broadcasting is an efficient method for simultaneous transmission of data to a group of users. But the multicasting rates are fixed in current IEEE 802.11 PHYs standard. In this paper, we propose a novel collision-detection based rateadaptation scheme (CDRA), which fully exploits the potential of rate adaptation capability of wireless physical layer, to improve service qualities of video multicasting. The received signal strength indication (RSSI) and packet error ratio (PER) are comprehensively used to detect collision. The PER-guided rate adjustment algorithm is performed when no collision happens. Otherwise the collision-avoid mechanism works. By detecting the collision, our scheme could adaptively select the maximum data rates for video multicasting. We construct a practical multicasting test-bed in IEEE 802.11b network and carry out extensive experiments. The results show that CDRA achieves throughput gain up to 166% and PSNR gain to 139% compared with existing methods.
