Cross-Layer Design for Enhanced QoS in Video Streaming Over Mobile Wireless Networks in Weibull Fading Conditions

This research paper proposes a novel cross-layer design framework of adaptive mechanisms and QoS strategies to improve the QoS of mobile video streaming in the face of Weibull fading harsh conditions. The unique component of the design is the application of adaptive mechanisms across application, MAC, and PHY layers. The robust optimization plan based on dynamic bitrate control, advanced error correction methods, and responsive real-time-aware resource allocation to urban-Weibull-mobility strengthen video streaming robustness. The SES results presented several improvements in terms of latency reduction and throughput enhancement, as well as the minimization of the error rate. These results depict high performance particularly in the most challenging conditions of high fading variability and realistic mobility distributions for urban mobile networks. In summary, a novel cross-layer adaptive video streaming mechanism for urban environments has been proposed, demonstrating remarkable performance enhancements. Finally, the study has proved that the cross-layer design is an optimal and efficient way of overcoming conventional and harsh challenging situations, adding a foundation for future direction of network architecture that can assure far more user-friendly and reliable mobile video services.
