【摘要】 车载自组织网络(Vehicular Ad Hoc Network,VANET)是一种将传感器技术、短距离移动通信及信息处理技术相结合的一种移动自组织网络(Mobile Ad Hoc Network,MANET)。然而,移动无线网络传输媒介固有的开放性、终端资源的受限性、终端的移动性以及网络拓扑结构的动态性,使得移动无线网络面临着较大的安全风险。如何保证在网络中进行安全高效的传输数据是我们要解决的问题。论文提出一种车联网中的安全高效路由方法来提高数据包的传输效率。模拟实验显示,此方法在数据包的递送率和端到端延时方面要优于洪泛路由方法。更多还原

【Abstract】 The conception of Vehicular Ad Hoc Network(VANET) has received immense attention all over the world since the successful implementation of VANET as a major step toward the realization of intelligent transportation systems. VANET is one kind of the Mobile Ad Hoc Network(MANET).However, due to the inherent open nature of mobile wireless communication environment, limitedresource and mobility of wireless terminals and dynamic network topology, wireless networks are facing greater security risk. How to ensure the safe and efficient transmission of data in the network, which is the problem we need to solve. In this paper, we propose a routing in VANET to improve the efficiency of transmission. Simulation results show that significant performance improvement has been achieved in terms of packet delivery ratio, end-to-end delay.更多还原
