| Summary: | Video streaming is becoming increasingly popular among the wireless users. However, supporting video
streaming over the wireless networks is not an easy task due to the dynamic radio propagation
environment, limited radio resources as well as Quality of Service (QoS) requirements of the video
streaming that need to be satisfied at acceptable levels. Most studies proposed to support video streaming
are computationally expensive to be used in Orthogonal Frequency Division Multiple Access (OFDMA)
based wireless IP networks. This paper evaluates video streaming performance under three well-known
algorithms that are more practical to be used in the OFDMA based wireless IP networks due to their
reduced complexity. It is demonstrated via computer simulation that Proportional Fair (PF) algorithm
outperforms other well-known algorithms by providing video streaming QoS at acceptable levels whilst
maximizing cell throughput. |
