Survivability in hierarchical telecommunications networks [PDF]
Networks, 2011 AbstractThe survivable hierarchical telecommunications network design problem consists of locating concentrators, assigning user nodes to concentrators, and linking concentrators in a reliable backbone network. In this article, we study this problem when the backbone is 2‐edge connected and when user nodes are linked to concentrators by a point‐to ...
