Abstract
Organizational network is one type of complex network featured distinct hierarchical structure, and the kernel of e-Government is information sharing and exchange based on organizational network. Therefore, the establishment of a manageable, scaleable and well-performed network structure becomes one of the crucial parts of the solution to the core problem in e-Government. This paper analyzes the characteristics of administrative organizational network, explores suitable strategies for optimization of organizational network model, defines a organizational tree model, and accordingly proposes a new organizational network model---DSHON (a Dual Scale Heterogeneous Organizational Network model). The proposed model is based on the structure of organizational tree, and the network performance is successfully promoted by adding shortcuts to the original tree according to the organizational distance between and the fitness of the nodes in the network. Simulation results show that the load allocation, transmission efficiency and network connectivity robustness are effectively improved in this model.
