The demonstration presents a network coding broadcast protocol experiment running on a remote open testbed, IoT-LAB. The emphasis is on both parts, that are ideally fitting and complementary: the use of testbed IoT-LAB, and a protocol for broadcast with network coding. IoT-LAB is a very large scale testbed, remotely accessible, and includes a total of 2728 nodes (in 6 sites), the nodes are mostly of type "wireless sensor nodes" with one wireless radio transceiver, and are well suited to perform wireless protocol experiments. On the other hand, network coding is a technique perfectly fitted to multi-hop wireless networks with lossy links, in some cases and conditions, it may even outperform any scheme using routing (non-coding): we had designed a generic broadcast protocol, called DRAGONCAST based on network coding for such networks, and which minimizes the assumptions made of the networks. A variant of this protocol was run on IoT-LAB: some results were presented previously. The demonstration is a live demonstration of the protocol on the newer nodes of IoT-LAB.
