Dynamic Ant Colony Optimization for Routing in Mobile Content Oriented Networks: Case of Moving Request Nodes

A huge amount of content exists in a network and the contents from mobile devices are also used. Content oriented networks are proposed as a new network architecture that conducts routing using the content´s ID instead of an IP address. When the content from a mobile device moves somewhere else, all the routing tables are generally re-created with the movement information that the mobile device sends. However, a routing scheme that uses ant colony optimization has attracted attention for supporting this process, but there is a problem with this optimization in that it cannot cope with moving contents and users enough. We previously reported a scheme that can cope with moving contents sources by using pheromones that are laid by themselves. In this paper, we propose a scheme that can cope with moving contents sources and users that require contents by using pheromones that are laid by the moving mobile devices. This proposed scheme is extended previous our scheme to, and can apply for not only case of moving contents sources but also the case of moving request users. Moreover, we conducted simulations to evaluate the performance of the proposed scheme.
