| Abstract(in English) | In Device-to-Device based social network services (D2D-based social network services), the data transmission is performed over two layer networks; a physical network where D2D communications are performed and a social network where users are communicated with each other. The performance of data transmission in D2D-based social network services depends on the topologies of those two networks. In such two layer networks, if cascading failures are occurred, the performance of data transmission is degraded in the two networks because a failure that is occurred in a network causes other failures in another network. In this paper, in order to decrease the impact of cascading failures for such D2D-based social network services, we consider a two-layer graph topology design based on cascading failures. In the topology design, node resilience is calculated from the topologies of the two networks, and then two optimization problems for the topology design are formulated so as to maximize the node resilience. In a optimization problem for the physical network, the optimal position of each device is derived for maximizing the node resilience. On the other hand, in a optimization problem for the social network, new relationships are added or the existing relationships are deleted. We evaluate the performance of the two-layer graph topology design with simulation. In numerical examples, we show that the optimal topology for each network can be derived by using our topology design. |
