Title: Resource allocatioin schemes for layered video broadcasting
Abstract: The explosive growth of content-on-the-move, such as video streaming to mobile devices, has propelled research on multimedia broadcast and multicast schemes. Multi-rate transmission strategies have been proposed as a means of delivering layered services to users experiencing different downlink channel conditions. In this presentation, we consider multiple Unequal Error Protection implementations of the Network Coding strategy for their inherent reliability features. In addition, we formulate resource allocation frameworks which are capable of jointly optimizing both the NC scheme in use and the system transmission parameters. Our proposed frameworks are adapted to the LTE stack and the integrated eMBMS technology. Furthermore, we establish that the choice of the NC technique and the way we define a resource allocation model, play a critical role in the radio resource footprint associated with a multimedia service.
Biography: I am a Research Associate at the School of Computing and Communications (InfoLab21, Lancaster University).I am currectly working on the Network error control for Rapid and Reliable Data Delivery (R2D2) Project supported by EPSRC under the First Grant scheme (EP/L006251/1).I have just finished my Ph.D. at the University of Florence (Firenze, IT). During the last three years I joined several research teams formed by people belonging to both the academic and the industrial world. In particular, I developed strong links with researchers belonging to different universities (such as the University of Edinburgh and the University of Novi Sad) who work on coding theory and multimedia communications over next-generation networks.My research interests focus on the mathematical modelling and optimization of broadcast and multicast communications over 3GPP's LTE/LTE-Advanced networks
