In this paper, we propose a novel measure, viral conductance (VC), to assess the
robustness of complex networks with respect to the spread of SIS epidemics. In contrast to …

Nowadays, a very useful platform is becoming widely used to deploy new services and
applications in the Internet: the overlay networks. These networks create a virtual topology …

Critical infrastructures are repeatedly attacked by external triggers causing tremendous
amount of damages. Any infrastructure can be studied using the powerful theory of complex …

The Next Generation Internet is intended to be an IP/WDM network which can be optimized
using virtual topology based traffic engineering. In this paper we study the NP-hard Virtual …

In the Cloud Computing Context, a virtual Machine (VM) can be migrated from one physical
host to a remote physical host while keeping it's address to avoid service discontinuity. The …

An important issue in dynamically constructed Virtual Private Networks (VPN) is how the
overlay topology is created and maintained. Classical VPN topologies, such as hub-and …
