Abstract

The wireless industry has seen a surge of interest in upcoming broadband wireless access (BWA) networks like WiMAX that are based on orthogonal frequency division multiplexing (OFDM). These wireless access technologies have several key features such as centralized scheduling, fine-grained allocation of transmission slots, adaptation of the modulation and coding schemes (MCS) to the SNR variations of the wireless channel, flexible and connection oriented MAC layer as well as QoS awareness and differentiation for applications. As a result, such architectures provide new opportunities for cross-layer optimization, particularly for applications that can tolerate some bit errors. In this paper, we describe a multi-channel video streaming protocol for video streaming over such networks. In addition, we propose a new combined channel coding and proportional share allocation scheme for multicast video distribution based upon a video's popularity. Our results show that we can more efficiently allocate network bandwidth while providing high quality video to the application.
