| Abstract(in English) | Our research group has proposed a VNT control method that is adaptive to traffic changes. The method is based on a dynamical system, called attractor selection, that models behavior where living organisms adapt to unknown changes in their surrounding environments and recover their conditions. One of important things of our VNT control method is how to determine attractors, i.e., VNT candidates. However, it is not taken into consideration what kind of VNT candidate should be constructed in our previously proposed VNT control method. In this paper, we propose a method to decide the VNT candidates. Our method prepares the VNT candidates by I-MLTDA, which is heuristic approach, and selects the VNT candidates from the viewpoint of average hop length. Furthermore, our method also prepares the VNT candidates in a random manner to give diversity of attractors so that various kinds of VNTs are searched by attractor selection. Evaluation results show that the success rate of the VNT control is improved by up to 20% when a half of the VNT candidates are selected from the viewpoint of average hop length and a half of the VNT candidates are prepared in a random manner, compared to the case when all the VNT candidates are prepared in a random manner. |
