Abstract
Abstract—In this paper we design and evaluate Ganges, a wireless mesh network architecture that can efficiently transport realtime 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.
