Spatial networks have some specialities such as open intermedium, dynamic topology, distributed cooperation and so on, which makes it face rigorus security challenge. Security is one of the most important issues and is desired to be resolved. Further more, routing plays a critical part in spatial networks. In case routing has any problems, the behaviors of the whole networks would decline and networks would even be paralyzed. As a result, the research of routing security mechanism is of great significance.The realization of routing security mechanism for spatial information networks on simulation platform is described in this thesis. The spatial information networks simulation platform was put up on the laboratory LAN. The realization of the simulation platform is based on the idea that wired networks simulating wireless networks with distributed running and centralized controlling. The control center manages the distributed terminal nodes. By virtual topology and virtual movement, the control center and the terminal nodes are simulated as the complex circumstances of spatial networks. Routing security mechanism is composed of reputation system, distributed intrusion detection system and intrusion response. Distributed intrusion detection system includes single intrusion detection and combined detection. When it is too difficult for single intrusion detection to judge malicious behaviors correctly, combined detection would be utilized to raise the accuracy of judgment and descend the rate of misjudgment. If intrusion detection system discovers malicious behaviors, reputation system will be utilized to descend the reputation degree of the nodes. If the reputation degree is descended to some extent, the nodes would be judged as malicious nodes. Intrusion response system would be activated to execute routing reconstruction. The malicious nodes would be isolated outside of the network. The guard against inside and outside attack for the network would be realized.The simulation of the routing security mechanism for spatial information networks on simulation platform showed that the routing security mechanism makes the spatial information networks routing protocols have good behaviors under common network threats. It guarantees the security of the networks.
