Abstract: Associated optimization algorithm is proposed based on improved competition network data in the invasion route map calculation method. This method calculates the average rate of intrusion detection network detection module, a real-time invasion of network data flow model, and get the invasion of network data flow characteristics, on the basis of the use of competition associated intrusion parameters optimization algorithm is used to select data network intrusion of cluster heads, and use the add competition factor of ant colony method for each of the routes in the network intrusion detection, effectively completed the route map of network intrusion data calculation. The experimental results show that the associated optimization algorithm based on improved competition calculation method of the network data in the invasion route map can effectively enhance the security and stability of the network communication.
