Router-level internet as a local-world weighted evolving network

For most networks in engineering and technology, the interplay of system dynamics, data traffics and network topology is critical to the network evolution and performance evaluation. Using the router-level Internet as a precise case study, this paper discusses a model that describes the growth of local-world weighted complex networks. This model combines the new vertices and new edges with the dynamical evolution of the weights locally, thereby generating a growing network with many statistical properties observed from real-world network examples. In particular, the model yields non-trivial time evolution of various vertex properties, including such as exponential and scale-free distributions of weights, strengths and degrees.
