Abstract
In this paper we design and evaluate Ganges, a wireless mesh network architecture that can efficiently transport real-time video streams from multiple sources to a central monitoring station. Video quality suffers from deterioration in the presence of bursty network losses and due to packets missing their playback deadline. Ganges spatially separates the paths to reduce inter-flow contention. It finds out a fair rate allocation for the different video sources. The wireless routers in the mesh network implement several optimizations in order to reduce the end-to-end delay variation. Ganges improves the network capacity by over 10-15% over a shortest path tree, and improves the video picture quality by 7-10 dB
在本文中，我们设计并评估了Ganges，这是一种无线网状网络架构，可以有效地将来自多个源的实时视频流传输到中央监测站。视频质量会因突发网络丢失和数据包错过播放期限而恶化。恒河在空间上分隔了路径，以减少流间的争用。它为不同的视频源找到一个公平的速率分配。为了减少端到端时延变化，网状网络中的无线路由器进行了多次优化。通过最短路径树，Ganges将网络容量提高了10-15%以上，并将视频图像质量提高了7-10 dB
