Dynamics of Realworld Networks
, 2007
"... In our recent work we found very interesting and unintuitive patterns for time evolving networks, which change some of the basic assumptions that were made in the past. The main objective of observing the evolution patterns is to develop models that explain processes which govern the network evoluti ..."

evolution. Such models can then be fitted to real networks, and used to generate realistic graphs or give formal explanations about their properties. In addition, our work has a wide range of applications: we can spot anomalous graphs and outliers, design better graph sampling algorithms, forecast future
SIMULATION WITH REAL WORLD NETWORK STACKS
"... Network simulation is used widely in network research to test new protocols, modifications to existing protocols and new ideas. The tool used in many cases is ns2. The nature of the ns2 protocols means that they are often based on theoretical models that might not behave in the same way as real ne ..."

networks. This paper presents the Network Simulation Cradle which allows real world network stacks to be used in a wrapper that allows the stacks protocols to be used in the ns2 network simulator. The network stacks from the open source operating systems Linux, FreeBSD and OpenBSD are included
Security Scheduling for Realworld Networks
"... Network based security games, where a defender strategically places security measures on the edges of a graph to protect against an adversary, who chooses a path through a graph is an important research problem with potential for realworld impact. For example, police forces face the problem of plac ..."

Multiplicative Attribute Graph Model of RealWorld Networks
, 1009
"... Large scale realworld network data, such as social networks, Internet and Web graphs, are ubiquitous. The study of such social and information networks seeks to find patterns and explain their emergence through tractable models. In most networks, especially in social networks, nodes have a rich set ..."

Estimating systematic risk in realworld networks
 In FC
, 2014
"... Abstract. Social, technical and business connections can all give rise to security risks. These risks can be substantial when individual compromises occur in combinations, and difficult to predict when some connections are not easily observed. A significant and relevant challenge is to predict the ..."

these risks using only locallyderivable information. We illustrate by example that this challenge can be met if some general topological features of the connection network are known. By simulating an attack propagation on two large realworld networks, we identify structural regularities in the resulting
Applications of Temporal Graph Metrics to RealWorld Networks
"... Abstract Real world networks exhibit rich temporal information: friends are added and removed over time in online social networks; the seasons dictate the predatorprey relationship in food webs; and the propagation of a virus depends on the network of human contacts throughout the day. Recent stud ..."

Diameter and Rumour Spreading in RealWorld Network Models
, 2015
"... The socalled ‘smallworld phenomenon’, observed in many realworld networks, is that there is a short path between any two nodes of a network, whose length is much smaller that the network’s size, typically growing as a logarithmic function. Several mathematical models have been defined for socia ..."

Distributed uniform sampling in realworld networks
 In Purdue University, CSD
, 2004
"... Uniform sampling in networks is at the core of a wide variety of randomized algorithms. Random sampling can be performed by modeling the system as a graph with associated transition probabilities and defining a corresponding Markov chain (MC). A random walk of prescribed minimum length, performed on ..."

This poses a significant practical challenge since typical large scale, realworld, unstructured networks tend to have non
