The Design Of Programmable Dynamic-simulation Interface For Qual Net

However,most of network simulations are performed for scenario-based simulation,in which the parameters of simulated network model are fixed and not changeable after beginning the simulation.For such scenario-based simulation,it is inefficient for presenting and analysis of a network at real time,since no parameters of network model can be changed.Especially,it is very unfavorable for the assessment of the Battlefield Network.So a Dynamic network simulation technology has been investigated in the previous work.However,the commands for dynamic parameters re-setting are manually sent to the Qualnet and the accuracy of such approach is not guaranteed.In addition,with a large amount of commends,a very high probability of manually input error is unavoidable.In this paper,a method of node information timing modification in the Qual Net simulation scene is proposed.Specifically,the development framework of the Programmable dynamic interactive interface include the PDSI interface and the Programmable dynamic interactive software is established for the Qual Net.The node information parameters which need to be modify will be packeted as the format of the data packet by the Programmable dynamic interactive software and be sent to the PDSI interface.And then through the PDSI interface and Qual Net simulator interaction user can dynamically,batch and real-time modify the node information parameters in the simulation environment.Thus make the Dynamic interference network simulation come ture and solve the problem of the large scale Battlefield Network simulation process can not be dynamic,batch,real-time configuration of node parameters.The experimental results show that the proposed interface design is very effective for large scale Battlefield Network simulation evaluation and testing.
