Abstract

The accessibility of good smartphones in 4G is encouraging mobile users to use video services. This huge increase in the usage of video communication over wireless networks poses many challenges according to fluctuations of wireless channel conditions along with user mobility. The challenge in providing video multicasting over wireless networks would most likely be the channel condition of each user in the same multicast group which is probably not identical due to location of the user and/or congestion of the network. In this paper, an adapted multicasting scheme has been proposed, which gracefully adapts the video quality to heterogeneous receivers and varying network conditions. Results obtained from simulation indicate that an enhancement of video quality under numerous channel conditions was through graceful degradation of these channels in terms of average throughput and packet loss ratio.
