摘要:

提出一种基于信道切换的车联网数据传输算法(DTA)。DTA算法考虑由车辆节点、中继节点和汇聚节点组成的三层网络,根据车辆的行驶方向进行节点的分类,提出不同的信道分配和切换机制,减少了数据传输的干扰。提出中继节点信息的快速扩散方法。提出紧急路况信息的优先传输方法,采用不同的队列将数据分类,并根据队列优先级选择传输数据。仿真结果表明,DTA算法能够有效地实现有用信息的快速传输,减少不必要的损耗,提高汇聚节点数据接收率,降低数据分组平均跳数和提高数据传输的覆盖率。在一定的条件下,DTA算法比AODV算法和AODV-L算法更优,可适用于快速变化的车辆行驶环境。

Abstract:

A data transmission algorithm of vehicle Ad Hoc network based on channel switching (DTA) was proposed.In the DTA,three network layers were considered,such as vehicle nodes,relay nodes and sink nodes.The vehicle nodes were classified by the information of vehicle’s driving direction.The vehicle nodes channel distribution and switching mechanism was proposed to reduce the interference of communication.Then a rapid transmission of relay nodes was proposed.A priority transmission method for emergency information was proposed to classify data with different queues and send data as their queues’ priority.Simulation results show that DTA can effectively achieve the rapid transmission of useful information,reduce unnecessary losses of energy,improve the data received rate of sink nodes,reduce the average hop number of data packets and improve coverage rate of data transmission.Under certain conditions,DTA is better than AODV and AODV-L algorithm,and is more suitable for vehicle driving environment of rapid change.

Key words: vehicle network, data transmission, transmission efficiency, channel switching
