Hybrid Mode Radio Link Control for Efficient Video Transmission over 4GLTE Network

Accessing video content on mobile devices has become widespread in recent years. The wireless network has to become content aware in order to offer enhanced quality of video service through efficient utilisation of the wireless spectrum. This paper proposes a scheme for end-to-end video transmission over Long Term Evolution (LTE) network. The network elements are made aware of the critical video frames that are transmitted through the network with the help of a field in Internet Protocol (IP) header which reduces the processing time. A new mode of operation called Hybrid Mode (HM) for Radio Link Control (RLC) of evolved NodeB (eNodeB) has been defined to ensure the reliable delivery of critical video frames which in turn increase the video quality. The simulation results with the proposed scheme show a 7% increase in received video quality in comparison to the legacy Unacknowledged Mode (UM) of RLC. The proposed scheme also removes the major jitter and provides a reduction in end-to-end delay by 99% when compared with the Acknowledged Mode (AM).
