PROJECT TITLE :

Resource Allocation Strategies for Network-Coded Video Broadcasting Services Over LTE-Advanced

ABSTRACT:

Video service delivery over 3GPP Long Term Evolution-Advanced (LTE-A) networks is gaining momentum with the adoption of the evolved Multimedia Broadcast Multicast Service (eMBMS). In this paper, we address the challenge of optimizing the radio resource allocation process so that heterogeneous groups of users, consistent with their propagation conditions, can receive layered video streams at predefined and progressively decreasing service levels matched to respective user teams. A key aspect of the proposed system model is that video streams are delivered as eMBMS flows that utilize the random linear network coding (NC) principle. Furthermore, the transmission rate and NC theme of each eMBMS flow are jointly optimized. The simulation results show that the proposed strategy will exploit user heterogeneity to optimize the allotted radio resources whereas achieving desired service levels for different user groups.
