Gateway Data Encapsulation Method for Vehicular Heterogeneous Network
摘要
Abstract
It is unavoidable that Vehicular Heterogeneous Network(VHN) need to exchange data by a gateway between each other.The data encapsulation method between heterogeneous networks is important for improving network protocol forwarding efficiency and determines the performance and reliability of the gateway.To improve the efficiency of gateway data forwarding,this paper proposes a new CAN/FlexRay network gateway data encapsulation method.Signals passing through the gateway in CAN and FlexRay networks are encapsulated into frames to make each signal frame contain more effective signals and improve the utilization of data.At the same time,it refines the BCBFD_LFS algorithm to confirm the optimum static time slot and decreases the time of operating message.Experimental result shows that the new method can improve the schedulability of messages,the network bandwidth utilization,and the data forwarding capability of gateway in VHN.关键词
