Kuipers, F.A. (author), Beshir, A.A. (author), Orda, A. (author), Van Mieghem, P. (author)Physical impairments, such as noise and signal distortions, negatively affect the quality of information transfer in optical networks. The effect of physical impairments predominantly augments with distance and bit rate of the signal to the point that it becomes detrimental to the information transfer. To reverse the effect of physical...conference paper 2010

Gourdin, E. (author), Omic, J. (author), Van Mieghem, P. (author)The effect of virus spreading in a telecommunication network, where a certain curing strategy is deployed, can be captured by epidemic models. In the N-intertwined model proposed and studied in [1], [2], the probability of each node to be infected depends on the curing and infection rate of its neighbors. In this paper, we consider the case...conference paper 2011

Omic, J. (author), Orda, A. (author), Van Mieghem, P. (author)Security breaches and attacks are critical problems in today’s networking. A key-point is that the security of each host depends not only on the protection strategies it chooses to adopt but also on those chosen by other hosts in the network. The spread of Internet worms and viruses is only one example. This class of problems has two aspects....conference paper 2009

Kleiberg, T. (author), Van Mieghem, P. (author)The Internet consists of a constantly evolving complex hierarchical architecture where routers are grouped into autonomous systems (ASes) that interconnect to provide global connectivity. Routing is generally performed in a decentralized fashion, where each router determines the route to the destination based on the information gathered from...conference paper 2009

Omic, J. (author), Hernandez, J.M. (author), Van Mieghem, P. (author)Communication networks are prone to virus and worms spreading and cascading failures. Recently, a number of social networking worms have spread over public Web sites. Another example is error propagation in routing tables, such as in BGP tables. The immunization and error curing applied to these scenarios are not fast enough. There have been...conference paper 2010

Li, C. (author), Wang, H. (author), Van Mieghem, P. (author)The largest eigenvalue ? 1 of the adjacency matrix powerfully characterizes dynamic processes on networks, such as virus spread and synchronization. The minimization of the spectral radius by removing a set of links (or nodes) has been shown to be an NP-complete problem. So far, the best heuristic strategy is to remove links/nodes based on the...conference paper

Lu, Y. (author), Zhao, Y. (author), Kuipers, F.A. (author), Van Mieghem, P. (author)More and more free multi-party video conferencing applications are readily available over the Internet and both Server-to-Client (S/C) or Peer-to-Peer (P2P) technologies are used. Investigating their mechanisms, analyzing their system performance, and measuring their quality are important objectives for researchers, developers and end users. In...conference paper 2010

The topology structures considered are the regular graph which represents the homogenous network structures and the complete bi-partite...conference paper 2009

(author)Personal Networks (PNs) are future communication systems that combine wireless and infrastructure based networks to provide users a variety of services anywhere and anytime. PNs introduce new design challenges due to the heterogeneity of the involved technologies, the need for self-organization, the dynamics of the PN composition, the...conference paper 2006

Doerr, C. (author), Tang, S. (author), Blenn, N. (author), Van Mieghem, P. (author)The key feature of online social networks is the ability of users to become active, make friends and interact with those around them. Such interaction is typically perceived as critical to these platforms; therefore, a significant share of research has investigated the characteristics of social links, friendship relations, community structure,...conference paper 2011

Blenn, N. (author), Doerr, C. (author), Van Kester, B. (author), Van Mieghem, P. (author)As Online Social Networks (OSNs) become an intensive sub- ject of research for example in computer science, networking, social sci- ences etc., a growing need for valid and useful datasets is present. The time taken to crawl the network is however introducing a bias which should be minimized. Usual ways of addressing this problem are sampling...conference paper

Winterbach, W. (author), Wang, H. (author), Reinders, M. (author), Van Mieghem, P. (author), De Ridder, D. (author)Biological networks exhibit intriguing topological properties such as small-worldness. In this paper, we investigate whether the topology of a metabolic network is related to its robustness. We do so by perturbing a metabolic system in silico, one reaction at a time and studying the correlations between growth, as predicted by flux balance...conference paper 2010

Tang, S. (author), Lu, Y. (author), Martín Hernández, J. (author), Kuipers, F.A. (author), Van Mieghem, P. (author)In recent years, a number of commercial peer-to-peer TV (P2PTV) applications have been launched. Yet, their mechanisms and characteristics are unknown. In this paper, we study SopCast, a typical proprietary P2PTV system. Treating SopCast as a black box, we perform a set of experiments that are suitable to analyze SopCast in depth.

Beshir, A.A. (author), Kuipers, F.A. (author), Van Mieghem, P. (author), Orda, A. (author)In WDM networks, survivable routing and wavelength assignment (SRWA) involves assigning link-disjoint primary and backup lightpaths. In the on-line SRWA problem, a sequence of requests arrive and each request is either accepted or rejected based only on the input sequence seen so far. For special networks, we establish on-line algorithms with...conference paper

Begtasevic, F. (author), Van Mieghem, P. (author)End-to-end quality of service is very likely to depend on the hopcount, the number of traversed routers. The hopcount also enhances our understanding of properties of the Internet topology.
