V2X network technology as the specific application of the Io T

while playing a huge role in the intelligent transportation system. With the continuous development of technology

V2X technology in China also develop rapidly. Through the analysis and discussion of V2X technology

Ad hoc network structure and hierarchical network architecture

this paper makes a summary of the existing V2X technology. Firstly

the concept of V2X is described in the first charpter. And then

the development of V2X technology at home and abroad is introduced

and several important applications of V2X in real traffic are described. Finally

the key issues in the technology are analyzed in order to provide further direction for the V2X.
