“…Indeed, the poor performance of multicast over WiFi has motivated a plethora of proposals [2], which include solutions such as Leader Based Protocols [3], consisting on one station providing feedback on behalf of a group of stations (and therefore requires to properly select one leader), or extensions based on, e.g., the use of "busy tones" [4,5], used by stations to interfere with the positive acknowledgments. However, most of these extensions require non-negligible modifications to 802.11 operation, or even adding new radio interfaces, and therefore their practicality is uncertain.…”

The IEEE 802.11aa Task Group has recently standardized a set of mechanisms to efficiently support video multicasting, namely, the Group Addressed Transmission Service (GATS). In this article, we report the implementation of these mechanisms over commodity hardware, which we make publicly available, and conduct a study to assess their performance under a variety of real-life scenarios. To the best of our knowledge, this is the first experimental assessment of GATS, which is performed along three axes: we report their complexity in terms of lines of code, their effectiveness when delivering video traffic, and their efficiency when utilizing wireless resources. Our results provide key insights on the resulting trade-offs when using each mechanism, and paves the way for new enhancements to deliver video over 802.11 Wireless LANs.

“…A thorough survey of multicast over wireless access networks is presented in [7]. This survey shows that various techniques have been proposed to solve the lack of reliability including link-layer reliability such as promiscuous reception of unicast transmission, Leader-Based Protocols or by polling some or all of the multicast group member requesting ACK.…”

Abstract-The use of multiple Access Points (APs) with one AP placed at the middle of a coverage area and the remaining placed at the edge may reduce the Packet Error Rate (PER) experienced by a group of multicast receivers. This paper shows that Spatial Diversity can augment the channel quality experienced especially by those nodes which are located farther from the master AP, i.e. the AP at the middle, however this study also demonstrates the need for error correction scheme. The aim of this analysis is to propose a means of enhancing the infrastructure end of an IEEE 802.11n Wireless Local Area Network (WLAN), such that multicast data can be delivered reliably in order to guarantee that the received video has an adequate Peak Signal to Noise Ratio (PSNR), but with the constraint that the Medium Access Control (MAC) and the Physical (PHY) layer of the receivers are not modified, hence a legacy IEEE 802.11n node may join the multicast group and experience good Quality of Service.

“…limited channel bandwidth, severe power constraint, unstable signals, interferences, etc.). For this reason, multicasting has attracted an increasing interest in wireless communications with extensive investigations [1]- [6]. With the advances of wireless communications, the demand of high-throughput multicasting is crucial, especially in services which require high-rate multicasting traffic, e.g.…”

This paper considers wireless multicast networks where network coding (NC) is applied to improve network throughput. A novel joint topology and cross-layer design is proposed to maximize the network throughput subject to various quality-of-service constraints, such as: wireless multicast rate, wireless link capacity, energy supply and network lifetime. Specifically, a heuristic NC-based link-controlled routing tree algorithm is developed to reduce the number of required intermediate nodes. The proposed algorithm facilitates the optimization of the wireless multicast rate, data flow of wireless links, energy supply and lifetime of nodes through a novel cross-layer design. The proposed joint topology and crosslayer design is evaluated and compared against other schemes from the literature. The results show that the proposed scheme can achieve up to 50% increase in the system throughput when compared to a classic approach.
