In order to solve the problem of the communication performance of degradation
which caused by multi-intersections in city environment and no sensitivity to individual node movements
an intersection-based geographical perception routing protocol in vehicular Ad Hoc network was proposed.The network gateways select road intersections to form the backbone of the route
ensuring a high probability of communication and meeting delay and bit error rate requirements.Mathematical formula of the average delay and the average number of hops were obtained on the basis of a two-way road model.Simulation results show that the transmission delay of IGPR is smaller
the number of hops of IGPR is less
and the communication performance of IGPR is better compared with the FRGR protocols and VRR protocols.
