Receiver nodes can join a multicast group by selecting a particular video stream and are dynamically elected as designated nodes based on their signal quality to provide feedback about packet reception. We evaluate the proposed application-layer rate-adaptive multicast video streaming over an aerial ad-hoc network that uses IEEE 802.11, a desirable protocol that, however, does not support a reliable multicast mechanism due to its inability to provide feedback from the receivers. Our rate-adaptive approach outperforms legacy multicast in terms of goodput, delay, and packet loss. Moreover, we obtain a gain in video quality (PSNR) of 30%\for point-to-multipoint and of for multipoint-to-point-to-multipoint streaming.enginfo:eu-repo/semantics/restrictedAccessArticle441759100051192440000610.1007/s10514-019-09851-6Multicast video streamingRate-adaptationIEEE 802.11Drones2-s2.0-85065042702
