However, the current state-of-the-art cellular solution is simply individually unicast the video stream to each node, which is extremely resource-inefficient. In this demo, we show how we perform reliable massive video multicasting over standard LTE links by combining the principle of cooperative networking and Random Linear Network Coding. We offload the majority of the traffic from LTE onto Wifi multicasts, thus increasing the efficiency of the LTE channel usage by multiple orders of magnitude. This demo has been demonstrated at the Mobile World Congress 2017 as a part of Nokia's booth to demonstrate the 5G stadium experience.}, keywords = {}, pubstate = {published}, tppubtype = {inproceedings} }

In this demonstration, we exhibit how we build a reliable low latency network out of a chaotic and dynamic wireless mesh network. We combine the principles of opportunistic routing and network coding to achieve this. We let the audience to interact with the nodes of the wireless mesh networks, i.e. causing node failures, link changes, etc. We demonstrate how our mesh network retains all of its flows intact without any service interruption despite these interactions and node failures.}, keywords = {}, pubstate = {published}, tppubtype = {inproceedings} }

Cooperation Group Size in Opportunistic Wireless Mesh: Optimal Versus Practical Proceedings Article

P. {Fitzek}}, year = {2018}, date = {2018-01-01}, booktitle = {European Wireless 2018 (EW 2018)}, address = {Catania, Italy}, abstract = {This paper investigates the performance of wireless mesh networks advocating for Opportunistic Routing (OpR) over traditional Single Path Routing (SPR). In OpR, all nodes overhearing the transmission can form a cooperation group and forward the fragments of the received message. The bigger the cooperation group, the more is the message sub-divided and the harder it gets to manage this process. If poorly managed, multiple duplicate fragments can be forwarded that downgrades the overall performance and destabilizes the routing protocol. In this paper, we propose several methods for shrinking the cooperation group and define the best one that can be later used as a part of the routing protocol. Using a testbed of 15 node WiFi network deployed in the office building, we show that the cooperation group size can be significantly reduced using our proposed methods. The throughput gain of OpR over SPR reaches as high as 51% in our testbed. We also show that only 3% of the average gain is lost when shrinking the cooperation group to less than one-third of its original size. The conducted measurement and the analysis of the results form the benchmark for potential performance evaluation of the mesh networks.}, keywords = {}, pubstate = {published}, tppubtype = {inproceedings} }
