The Traffic Matrix Estimation Algorithm Based on Hybrid Niche and Artificial Immune System

In order to mitigate the estimation accuracy of traffic matrix,a new algorithm HNAIS (Hybrid Niche and Artificial Immune System algorithm) is presented by Hybrid niche and artificial immune system.In this algorithm,the Traffic Matrix model is proposed with link load and connectivity matrix at first,which is solved by artificial immune system.Then,the calculation result is optimized with niche technology to avoid falling into the local optimum.At last,a simulation with OPNET and MATLAB was conducted to study the key influence factors.The result shows that,compared to other algorithm,HNAIS has better adaptability.
