摘要：

根据车辆自组网上层应用种类丰富、服务质量(QoS)需求多样的特点，结合层次设计思想，设计并实现一种采用注册回调式API和共享内存通信机制的端到端通信软总线。该软总线支持TCP、UDP和AUDP等多种传输协议，便于系统松耦合集成和信息透明传输。仿真实验结果表明，对于设立不同优先级的应用，该软总线能够满足端到端时延、时延抖动和数据包成功到达率等QoS要求。

Abstract:

According to the widespread use and various Quality of Service(QoS) for VANET application, an end-to-end communication software bus with callback function, registered API and communication mechanism of virtual shared memory is proposed under the guidance of design method. This software bus supports TCP, UDP AUDP(Acknowledged User Datagram Protocol) and various transport protocols extension, and is convenient for loosely coupled system integration and transparent information transmission. Simulation result indicates that the software bus is able to satisfy diverse QoS, including average delay of end to end, average jitter and packet delivery radio by setting up priority.

Key words: Vehicle Ad Hoc Network(VANET), software bus, shared data area, delay, Quality of Service(QoS)
