This paper,based on the application background of MANET accessing Internet,with a view to the crucial function of dynamic gateway in network accessing,proposed a new three-layer programming model for placement and selection dynamic gateways.A decision node,which has coordination control function,was introduced into the model,and was used to harmonize the utilization of gateways and routes.The three layers make decisions interactively to mediate the relationship between the network overall benefit and the node local interests.The model,as the basis of the gateway configuration,optimized the placement of the gateway.The simulation results indicate that the performance of delay,overhead and throughput has promoted after the model was introduced,which validates the validity of the model.
