World city topologies

Small - World Internet Topologies

Recent work has shown the prevalence of small-world phenomena [28] in many networks. Small-world graphs exhibit a high degree of clustering, yet have typically short path lengths between arbitrary vertices. Internet AS-level graphs have been shown to exhibit small-world behaviors [9]. In this paper, we show that both Internet AS-level and routerlevel graphs exhibit small-world behavior. We attr...

Computer Simulations of VANETs Using Realistic City Topologies

Researchers in Vehicular Ad Hoc Networks (VANETs) commonly use simulation to test new algorithms and techniques. This is the case because of the high cost and labor involved in deploying and testing vehicles in real outdoor scenarios. However, when determining the factors that should be taken into account in these simulations, some factors such as realistic road topologies and presence of obsta...

The Changing Configurations of World City Networks

City Resilience: Analysis of Strategies World-wide

In recent years, resilience has become an important goal for cities, particularly in the face of political uncertainty, climate change and increasing urbanisation. Resilience theory has yielded informative lessons and brought new perspective when preparing for, and responding to vulnerabilities cities face today, such as natural hazards and social inequalities. However, critical questions on ho...
