Dual Handover vs. QoS for Real Time Broadband Video Streaming over WiMAX Networks

Abstract

The consistent superiority in terms of reduced packet loss to enhance video quality it is what this paper proposing. Prior investigation of video streaming over wireless networks has assumed a single access point and a homogeneous wireless technology. With different channel effects and conditions a long side the Hard Handover (HHO) consequences on mobile broadband video streaming, IEEE 802.21, it is now becoming possible to offer seamless video streaming and harmonizing that influence. The paper presents a video streaming transport scheme that is more capable of exploiting the expected reduced latencies of real time video streaming content distribution networks. Broadband Video Streaming (BVS) with adaptive packet retransmission promises better video quality during an (HHO) than both raw UDP transport and traditional congestion-controlled streaming, making it attractive to mobile broadband video streaming services. It achieves this by distinguishing between high congestion and poor channel conditions, the latter of which an HHO induces, and by prioritized retransmission according to picture type.
