Routing Node Selection Strategy For V2X Information Transmission Network

“Vigorously develop intelligent transportation” as an important guiding ideology of the transportation power strategy, leading the development trend of future transportation. As an important part of promoting the integration of information technology and transportation industry, vehicle-road communication collaborative technology occupies a major strategic position. In this paper, we study the routing node selection strategy for the communication system architecture. For the initial construction process of the network, the road side node selection strategy and the vehicle relay node selection strategy were proposed to improve the network structure construction process. It is proposed that the development of VANETs technology is becoming increasingly important, and as a core component of ITS, the applications of VANETs technology covering information services such as traffic emergency alerts, road safety, in-vehicle on-demand entertainment, and vehicle collision prevention, have a very wide range of applications and research potential. Unlike MANETs network where the power limitation and energy limitation of the nodes makes the improvement of the network performance very limited, the nodes in VANETs network consist of high speed moving vehicles with unlimited power and high energy powerful computing capability.
