There is an increasing user demand for high-quality content-rich multimedia services. Despite their advantages, current wireless networks in general and wireless mesh networks in particular have limitations in terms of quality of service (QoS) provisioning, especially when dealing with increased amounts of time sensitive traffic such as video. This paper presents video load balancing solution (ViLBaS), a load balancing-based mechanism which enhances delivery performance of video services over multi-hop wireless mesh networks and improves user quality of experience (QoE) levels. ViLBaS involves performance monitoring at the level of the nodes and load balancing by off-loading traffic from loaded nodes to less loaded neighboring nodes. Simulation-based results show how the proposed ViLBaS improves video delivery performance in terms of both QoS and QoE metrics [delay, throughput, packet loss, and peak signal-to-noise-ratio (PSNR)]. The comparison is performed against three other traditional approaches in different network topologies, for diverse video flow distributions, and different sizes for the video queue.

用于在负载无线网络条件下提高视频质量的负载平衡解决方案

用户对高质量内容丰富的多媒体服务的需求不断增加。尽管具有优势，但当前的无线网络和无线网状网络通常在服务质量 (QoS) 配置方面存在局限性，尤其是在处理视频等对时间敏感的流量增加时。本文提出了视频负载平衡解决方案 (ViLBaS)，这是一种基于负载平衡的机制，可提高视频服务在多跳无线网状网络上的交付性能并提高用户体验质量 (QoE) 水平。ViLBaS 涉及节点级别的性能监控和负载平衡，通过将流量从负载节点卸载到负载较低的相邻节点。基于仿真的结果显示了所提出的 ViLBaS 如何在 QoS 和 QoE 指标 [延迟、吞吐量、丢包率和峰值信噪比 (PSNR)] 方面提高视频传输性能。针对不同的视频流分布和不同大小的视频队列，针对不同网络拓扑中的其他三种传统方法进行了比较。
