Vehicle‐to‐vehicle communication is an important part of the modern intelligent transportation system. Most of the existing vehicle networks are based on central structures, which are prone to single point of failures, and may consequently result in system paralysis. In order to increase the network fault tolerance and maintain the stability of the network system, the authors propose a vehicle network model based on the peer‐to‐peer (P2P) network. In this model, the base station and the roadside units will no longer be necessary facilities. The vehicles can be used as relays to directly participate in the exchange and transfer of information. The relay nodes (vehicles) are selected based on the degree distribution and the consensus algorithm. The real‐time capability, efficiency and cost effectiveness of the proposed P2P model is verified through experimental results.
