Abstract (in Japanese) (See Japanese page) 
(in English) In beyond 5G network, the device-to-device communications has been actively studied. These devices are wirelessly connected to each other and can receive and send information by forming a wireless multihop network (WMN). In WMN, there are still some issues that need to be resolved, like due to the uncertainty of source node choosing the path to send the message, the performance of network capacity can degrade drastically. To solve this problem, in this paper we study a factor graph (FG) representation, which selects multihop path and a nested lattice code (NLC), which is used to reduce the error rate on the transmitted message in the WMN. Our simulation results reveal that the network capacity with FG is always higher than as well as the computation time is extremely lower than the case without FG regardless of the number of nodes. With NLC, the network capacity increases more, but computation time becomes larger.
