Media Streaming Management In Heterogeneous Wireless Systems
2 years (Mar 2012 - Feb 2014)
Mobile video is getting pervasive enabled by the increasing penetration of smart handhel devices and the high data rates supported by novel wireless technologies. CISCO predicts that mobile data traffic will increase 26 times between 2010 and 2015 with a compound annual growth rate (CAGR) of 92 percent. More importantly, mobile video is expected to have the highest growth rate of any application category with a CAGR of 108 percent between 2010 and 2015. Over this forecast period, business video conferencing will grow sixfold. Additionally, almost 66 percent of the world’s mobile data traffic will be video by 2014. This unprecedented increase puts significant pressure on network operators to improve the spectral efficiency of their systems by adopting the state of the art technologies proposed in the long-term evolution (LTE) of cellular standards. However, these technologies alone would not suffice as their expected gain would not match the increase in mobile data. Hence, the concept of heterogeneous wireless networks in which overlays of different coexisting base stations (BSs) collaborate to achieve traffic load distribution and improved quality of service (QoS) evolves as a key solution to improve the system spectral efficiency. These coexisting BSs include not only different scales of cellular base stations, such as macro, micor, pico, and femtocell, but also BSs operating other technologies such as wireless local area networks (WLANs) and Worldwide Interoperability for Microwave Access (WiMax).
In this project, we aim to develop solutions that improves the user media streaming experience over heterogeneous wireless networks. These solutions will address different relevant aspects in mobile video including optimized streaming cost strategies efficient media transmission techniques. Additonally, these solutions would consider different scenarios including streaming scalable and non-scalable over heterogeneous networks.
