Abstract: As to the problem of Quality of Service(QoS) and congestion in the wireless communication network, the information dissemination management simulation system based on the technology of virtual overlay network is introduced. By analyzing the requirement of mobile communication, this paper simulates typical application environment, and makes great effort to study and explore the information dissemination management technology with OMNeT++ simulation tool. The overlay network is built to implement the key technology of network state awareness, QoS routing calculation and service transmission optimization, which constructs a information dissemination management simulation system. Evaluation result shows that the system can improve the business performance of wireless communication network.

Key words: information dissemination management, access traffic control, link detection, measurement of link state, Quality of Service(QoS)
