    Abstract

    This demo presents a novel routing and scheduling scheme, named Enhanced-Backpressure over WiFi (EBoW), that obviously outperforms the dominant approach of a shortest-path routing (SRCR) combined with the classic CSMA/CA scheduling policy of 802.11 networks. The new scheme combines aspects of load-balancing and shortest-path routing and enhances the CSMA/CA scheduling, maximizing the throughput performance, while keeping low end-to-end delay. We perform a comparative demonstration of video streaming over an ad-hoc 802.11 network, using EBoW and SRCR, where the latter one is a state-of-the-art shortest-path routing algorithm. The new scheme delivers a smooth and jitter-free video playback experience, while the SRCR scheme experiences noticeable jitter and rather frequent distortions. The demo clearly demonstrates the performance superiority of the new implemented scheme, as compared to the other one. The implementation of both schemes relies on the well-known Click framework.
