Rich-Club Phenomenon of the Internet Topology
Shi Zhou · IGI Global eBooks · 2008
This chapter introduces a recently discovered structure of the Internet, namely the rich-club phenomenon (Zhou & Mondragón, 2004a). The significance of this discovery is that an appreciation of the rich-club phenomenon is essential for a proper examination of global Internet characteristics, such as routing efficiency, network flexibility, and robustness (Zhou & Mondragón, 2004b). Today, rich-club connectivity has been adopted by the networks research community as a topology metric to characterise the Internet structure (Mahadevan et al., 2005).
