A robust optimization approach to backup network design with random failures
—This paper presents a scheme in which a dedicated backup network is designed to provide protection from random link failures. Upon a link failure in the primary network, traffi...

Improving TCP performance in ad hoc networks using signal strength based link management
Mobility in ad hoc networks causes frequent link failures, which in turn causes packet losses. TCP attributes these packet losses to congestion. This incorrect inference results i...

Graph transformation approaches for diverse routing in shared risk resource group (SRRG) failures
Failure resilience is a desired feature of the Internet. Most traditional restoration architectures assume single-failure assumption, which is not adequate in present day WDM opti...

A Scalable Algorithm for Survivable Routing in IP-Over-WDM Networks
In IP-over-WDM networks, a logical IP network has to be routed on top of a physical optical fiber network. An important challenge hereby is to make the routing survivable. We call...
