Abstract

Content-oriented networks are proposed as a novel network architecture in which routing is conducted using the content ID instead of an IP address. In content-oriented networks, there is a problem that users cannot discover contents when the mobile communication device that has the contents moves about. Therefore, many studies have been undertaken to solve this problem. In conventional research, by applying ant colony optimization (ACO), Manome and Asaka tracked the movement of contents by adding a pheromone to the route of the mobile device itself. This method improved the discovery rate after movement compared with the case without the pheromone, indicating the effectiveness of their method. However, since the path searching by ACO depends on the behavior of movement of the mobile device, there is a problem of detouring along the route to the contents in some cases. To solve these problems, we used the true slime mold algorithm instead of ACO. In the simulation, we compared our results with those of the conventional method of using ACO to evaluate the performance of our proposed method.
