Abstract
Publishing resources on a virtual network is a way to realize efficient data-distribution mechanisms. To this extent, each node needs to discover the other nodes, create neighborhoods and advertize its own resources. This chapter presents different techniques for making resources "discoverable," considering two approaches dubbed as unstructured networks and structured networks. We discuss properties of different protocols in terms of signaling overheads and distribution efficiency. © 2011 Springer Science+Business Media B.V.
