Poryev G., Schloss H., Oechsle R. CARMA based MST approximation for multicast provision in P2P Networks

The Minimum Spanning Tree (MST) problem is one of the most popular and important problems in the research area of distributed computing and  networks. Contrary to the theoretical models where we usually have a global knowledge of all nodes and the corresponding distances for MST  construction, in a realistic network (e.g., Internet) a node always has to rely on local knowledge only, that is it neither knows all other nodes nor exact  distances between these nodes. In this paper we propose an approach for MST approximation based on local knowledge of a small subset of existing  nodes by using the CARMA metric as a distance substitute. According to the evaluation results, our approach achieves a good MST approximation with  respect to a communication cost and avoids extraneous communication needed for latency measurements.
