Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, the complication of wiring harnesses and physical restrictions of the wiring in cars become one of the major issues due to the increase in the number of devices installed in vehicles for autonomous driving, driver assistance features, and so forth. As concerns this issue, multi-hop wireless communication is thought to be a substitute for existing wired communication that uses wiring harnesses as a communication medium. However, it is technically difficult to replace the existing wired communication network with a single wireless multi-hop network since there is various sort of simultaneous communication that requires individual communication quality, such as driving-related control signal, switch operation signal, and a signal from sensors. In this paper, we propose a method to allocate communication resources, which constructs a hierarchical network with different channels and utilize the Ford-Fulkerson algorithm, according to required communication quality. The simulation results clarify that the proposed method achieves lower end--to--end delay and higher communication success rate by optimizing the resource allocation and communication.
