The biggest challenge of vehicular ad hoe network routing protocol lies in the mismatch between the direction of moving vehicles and routed data. In order to deal with this mismatch, a mesh based routing protocol with a two-tier network architecture is proposed. By using mesh nodes deployed at intersections, data can be routed through an optimized path which can improve the delivery ratio and reduce the consumption of network resources. The simulation uses the mobility model processed from the GPS data of taxis mnning in Shanghai urban areas. The result shows that the proposed protocol outperforms the existing flooding protocol.展开更多
