Abstract
For most technical networks, the interplay of dynamics, traffic, and topology is assumed crucial to their evolution. In this Letter, we propose a traffic-driven evolution model of weighted technological networks. By introducing a general strength-coupling mechanism under which the traffic and topology mutually interact, the model gives power-law distributions of degree, weight, and strength, as confirmed in many real networks. Particularly, depending on a parameter that controls the total weight growth of the system, the nontrivial clustering coefficient , degree assortativity coefficient , and degree-strength correlation are all consistent with empirical evidence.
