In this paper efficient transmission of video streaming across PHY (PHYsical) and MAC (Medium Access Control) layer of Mobile WiMAX (Worldwide Interoperability for Microwave Access) IEEE 802.16e using HARQ (Hybrid Automatic Repeat ReQuest) technique is proposed. HARQ utilizes both FEC (Forward Error Correction) and ARQ (Automatic Repeat ReQuest) technique which reduces the delay, packet loss rate and increases the throughput efficiently under the prescribed quality of service constraint. In this research work, the authors have made a comparative analysis of the throughput, delay and jitter on a video traffic application with and without ARQ implementation. Adaptation of Modulation and coding scheme at PHY layer along with MAC layer HARQ are considered in this paper.
