Abstract

In this dissertation, I have addressed some pertaining research problems related to power saving balancing the opposing goals of high video quality during video transmission over broadband wireless network. Comparison is done to select the best video codec, which can provide better video quality at lower data rates, thus minimizing power requirement for transmission. Modeling and prediction technique for video traffic at an intermediate node is presented. A novel cross layer architecture and algorithm is presented based on video traffic modeling and prediction for DRX/Sleep mode power saving. It utilizes application layer information of video frames transmitted over Real Time Protocol (RTP) for determining the sleep opportunities at the mobile station in an Orthogonal Frequency Division Multiplexing (OFDM) based network like TDD-LTE and WiMAX, without compromising the QoS. Expression for maximum sleep duration is derived for a video transmission session in terms of video encoding parameter and wireless channel parameter. The study reveals related results with respect to above area.
