Evolution formation and characteristic analysis of a class of information systems based on complex networks

A class of information systems composed of backbone networks and access networks is very popular. According to the complexity and organization forms of the class of information systems, two evolution formation mechanisms of the systems are constructed based on complex network theory. One of the mechanisms uses pre-planning and random access strategies, and the other uses pre-planning and preferential access strategies. Different planning schemes and access ways are modeled. Furthermore, an example of information systems is introduced, and the network construction laws of information systems are verified and analyzed by numerical simulation.
