Abstract: In view of the existence of slightly curved surfaces and local minima problems with the application of the BP neural network algorithm, ergodic BP algorithm based on minimal point escape was proposed to achieve better convergence effect. The improved BP algorithm was applied to the wireless network intrusion detection system. Experiments show that, the improved BP algorithm enhances the accuracy and real time of intrusion detection systems.
