Segmented video distribution over WiMAX: Proposed approach and experimental methodology

In this article the issues of video delivery over wireless BWA (Broadband Wireless Access) networks are considered. The authors briefly review published existing up-to date solutions and proposals focused on video applications in BWA networks, with special attention drawn to IEEE 802.16 (WIMAX) standard-based paths of network configuration. Provision of the flexible QoS concept together with promising coding, modulation and other MAC, PHY essentials laid in the core of the WiMAX (Worldwide Interoperability for Microwave Access) standard are admitted to provide a leverage to tackle bit-variable rate, stringent delay, high throughput, video traffic sensitive demands in multimedia service for multi-user environment offered by telecommunication operators. Novel technique is presented for video transmission over WiMAX, which exploits structural features of the MPEG-family (Moving Picture Expert Group) compression standards and QoS flow-oriented MAC connections adopted by the IEEE802.16. The proposed new approach, hopefully, could tackle ever-pressing challenges for any service provider - to offer maximum video-quality for most end-users and for less resources. Under severe channel-congested conditions the outlined model is going to demonstrate more optimistic results, as regards with throughput and BER when compared with conventional framework.
