Aiming at the characteristics of vehicle sensor networks, a ubiquitous interconnected vehicle sensor network architecture based on clustering directed diffusion and intelligent routing is proposed. The architecture makes full use of the multi-path networking and self-organizing capabilities of vehicle sensor network nodes, and forms a hybrid logical topology HLT-C & DD combining wireless Ad Hoc network and traditional network by using clustering directed diffusion mechanism. Through intelligent routing Function Provides intelligent diversion for data aggregation in the network. Theoretical analysis and simulation results show that this architecture can improve the overall performance of ubiquitous vehicle network.
