Abstract:
In this article, we evaluate network coding algorithm COPE using different topologies, traffic intensities and distributions in order to search for guidelines for network deployments and for better exploring the advantage of network coding opportunities. Using different network topologies we identify nodes that perform well with coding and nodes that do not find any coding opportunities. Results show that in all analyzed networks, although the COPE performs well in decreasing average network delay, there are only few nodes that perform coding operations and up to 25% of nodes that find no coding opportunities at all. Also in, randomly distributed traffic, there is only a fragment of packets that find coding pairs, thus showing place for significant improvements either in used algorithms or in designing networks.
