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 ...

Drawing telecommunication networks [PDF]
, 1995 The design and analysis of cost effective survivable telecommunication networks is a very important problem. We study techniques for visualizing survivable telecommunication networks. The visualization of telecommunication networks is very useful in aiding the design process of minimum cost networks and the management of network operations.
