【摘要】：车载异构网络之间需要利用网关进行数据交换,数据封装方法关系到网络协议转发效率,决定了网关的实时性和可靠性。为提高网关数据转发效率,提出一种新的CAN/FlexRay网络网关数据封装方法。将CAN和FlexRay网络中通过网关的信号封装到帧,使得每个信号帧中包含更多的有效信号,提高数据利用率,同时使用改进的BCBFD_LFS算法确定最佳静态时隙,减少消息处理时间。实验结果表明,该方法能提高车载异构网络中的消息可调度性、网络带宽利用率以及网关的数据转发能力。
[Abstract]:Vehicle heterogeneous networks need to use gateways to exchange data. The method of data encapsulation is related to the efficiency of network protocol forwarding and determines the real-time and reliability of the gateway. In order to improve the efficiency of data forwarding, a new data encapsulation method for CAN/FlexRay network gateway is proposed. The signals in CAN and FlexRay networks are encapsulated into frames through the gateway, which makes each signal frame contain more effective signals and improve the data utilization. Meanwhile, the improved BCBFD_LFS algorithm is used to determine the best static time slot and to reduce the message processing time. The experimental results show that the proposed method can improve the message schedulability, network bandwidth utilization and the data forwarding ability of the gateway in the vehicle heterogeneous network.
