Design of low-latency data transmission scheme for vehicle network under high speed mobile scenario

In this paper,a low-latency data transmission scheme for autonomous vehicles in high-speed mobile scenarios was designed.In this proposed scheme the macro-nodes and micro-nodes were combined to form an access group dependent on a powerful fog node server so as to implement allocation and schedule of user-requested resources.The simulating experiment demonstrated that the delay of the present scheme was reduced to less than 1 ms compared to the traditional long term evolution (LTE) scheme while the data transmission error rate was slightly higher
