Abstract
In recent years, due to the widening of network bandwidth and the technical advancement in the performance of communication terminals, a wide variety of digital contents have been actively exchanged over the Internet by a large number of users. Then, in order to suppress the load on the network and the delay in exchanging contents, systems consisting of a Peer-to-Peer network and /or a three-layer structure of Cloud-Fog-Edge have come to be often used. We assume a content sharing system of the same structure in which the fog part is replaced with a Dynamic Fog composed of a set of peers, and in this system configuration, we propose an improvement of the conventional method for efficient content sharing by having each peer maintain appropriate replicas of the contents according to the time change of the number of users in a city. Furthermore, we evaluate the proposed improvement with computer simulations and discuss its effectiveness.
