| Abstract: | With the influence of the migration threshold value on the performance of dendritic cell algorithm(DCA) being considered during the network intrusion detection，the way to determine the migration threshold is presented to improve the performance of DCA.According to the real network behavior with the characteristics of continuity，the particle swarm optimization (PSO) is employed to determine the migration threshold which will be the used to analyze the network data.The simulation results show that the improved way can increase the accuracy of intrusion detection of DCA. |
