Demo of the ABCD protocol

In this demo, we present a cross-layer protocol for video streaming in mobile ad-hoc networks. The protocol, called ABCD,  builds an maintains a multi-tree overlay network, optimised w.r.t. the underlying wireless network; then, the video descriptions are sent independently, one on each tree. The proposed protocol allows video streaming with negligible loss rate and short delay, even under high churn, thanks to the path independence among the descriptions.

The following videos show the trees build-up for the cases of 30 and 100 node MANETs. Two description are used in both cases, resulting in a double distribution tree.
