- Abstract
- Multicast is a more efficient method of supporting group communication than unicast, as it allows transmission to multiple destinations using fewer network resources. The demands for video multicast have been increasing rapidly with the improvements in multimedia technologies. Therefore, the reliable delivery of video frames is an important task. Recently, IEEE 802.11aa standard defined new features for the reliable multicast. However, there are still a few limitations. Therefore, in this paper, we propose a modified block acknowledgment scheme for video streaming to overcome the scalability limitation of the block acknowledgment scheme in IEEE 802.11aa standard. Simulation results show that our modified block acknowledgement scheme performs well in terms of reliability and peak signal to noise ratio.
