车载自组织网络(VANET)使车辆之间的传输成为可能，而不需要基础设施。然而，自组织网络也增加了网络的冗余性。为了减少网络冗余，提高VANET的效率，我们引入了一种新的路由协议：基于交集的转发协议(IBFP)。在城市区域，我们在每个交叉口设置虚拟端口。虚拟口岸通过在路口前拦住等待红绿灯的车辆来服务。VP将从所有经过的车辆收集需要转发的所有分组。当VP离开这个交叉点时，它会将所有数据包的副本传输给下一个VP。随着VP的移动，分组可以像流行过程一样在很短的时间内传输到每个路口。目的地车辆可以接收成功率很高的包。这一流行过程仅存在于VP之间。因此，在保证较高成功率的前提下，提出的IBFP能够以较小的时延和冗余度进行分组传输。
Vehicular ad hoc networks (VANETs) make the transmission between vehicles possible without infrastructure. However, ad hoc networks also increase the redundancy of networks. To decrease the redundancy of networks and make VANETs more efficient, we introduce the new routing protocol: intersection-based forwarding protocol (IBFP). In urban-area, we set virtual ports (VP) at each intersection. The virtual port is served by stopping vehicle which is waiting for the traffic light in front of the intersection. VP will gather all the packets that need to be forwarded from all passing by vehicles. When VP leaves this intersection, it will transmit all the copies of packets to the next VP. As the movement of VP, packets can be transmitted to every intersection in a very short period of time like the epidemic process. Destination vehicles can receive packets with high success rate. The epidemic process only exists among VPs. Therefore, on the premise of high success rate, the proposed IBFP can transmit packets with less delay and redundancy.
