“…In comparison with our work in [8] a straightforward simulation of DCCP, SCTP and UDP over a single fixed WiMAX link occurred. It appears that the channel may have been error free, though congestion occurs.…”

The need to respond to congestion and channel loss over not one but two wireless links is an impediment to video streaming between one mobile user device and another via an intervening IP network. The result can be poor wireless channel utilization and interruptions to the streaming process. This paper proposes that multi-connection streaming will avoid the need for application-specific cross-layer intervention to address this problem. In considering IEEE 802.16e (mobile WiMAX), the paper demonstrates that multi-connection streaming is certainly necessary but only sufficient if an appropriately sized Time Division Duplex frame is selected. Received video quality will also depend on correct determination of the number of connections and the compression ratio of the video itself. The quality of the received video must be traded off against the time to stream the complete video sequence, which in term is determined by the number of connections.

“…Some of this work describes simulation results, or measurements on networks using the older "fixed WiMAX" standard. For example, [27] and [28] analyze the performance of video over mobile WiMAX networks using simulations. [29] [30] [31] describe field measurements from experiments carried out over research testbeds.…”

Abstract-In the last few years, there has been an increasing awareness of the need to evaluate new mobile applications and protocols in realistic wireless settings, and platforms such as the GENI WiMAX testbeds have been developed to fulfill this need. However, wireless testbed users have experienced frustration when straightforward usage scenarios do not consistently agree with the high data rates that are advertised by the wireless technology. This work seeks to clarify the performance characteristics of two GENI WiMAX testbeds under various wireless signal conditions and network traffic patterns. By measuring the performance of several popular wireless Internet applications in two very different wireless environments, we gain a deeper understanding of how a researcher may expect the GENI WiMAX platform to behave. Our findings include some counterintuitive results, e.g. that increasing signal quality can reduce application throughput, and that applications using a single TCP flow may achieve as much as 72% less throughput than an application in an identical setting that uses multiple TCP flows. With this work, we hope to help other researchers design realistic experiments on wireless Internet systems, understand the perceived shortcomings of the GENI WiMAX platform, and interpret their experimental results in the context of the wireless setting in which the experiment was conducted.

“…Results showed an improvement in the video quality comparing PR SCTP with UDP. Another interesting works regarding MPEG-4 video transmission over wireless technologies are presented in (Nosheen et al, 2007) and (Chughtai et al, 2009). In the first work, authors compared SCTP with UDP and DCCP (Datagram Congestion Control Protocol) (Kohler et al, 2006).…”

“…In the presence of background traffic, the results also showed that SCTP and DCCP outperformed UDP. As an extension to this work, Chughtai et al (2009) carried out a similar study to compare the QoS performance of SCTP, UDP, and SCTP transmitting video in a WiMAX network. The simulation scenarios included downloading or uploading MPEG-4 video traffic using a different number of subscribers, different packet sizes, and a variable video rate.…”
