| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have proposed a software-defined multicast for efficient simultaneous content delivery in crowded scenes such as a stadium. The basic concept of the proposed system lies in seperating control plane and data plane.The control plane uses private LTE called sXGP and the data plane uses Wi-Fi multicast. When packet losses occur in multicast, the lost packets are complemented by D2D communication. In this article, we propose a D2D pairing algorithm to complement lost packets between user devices. We experimented the efficacy of the proposed algorithm in NS-3 network simulator and show that our method can greatly mitigate the packet loss rate by D2D complementation. |
