一种多接口多信道VANET动态信道分配算法研究
为了合理地实现多接口多信道车载自组织网络（VANET）车辆节点间通信信道的动态分配，提出了一种基于通信双方车辆节点信道切换队列的动态信道分配算法。定义了车辆节点的射频接口状态，给出了信道的性能因子以及信道切换队列的生成方法，通过综合考虑通信双方车辆节点的射频接口状态和信道切换队列，快速自主地建立通信链路，从而解决了信道公平接入和分配不合理的问题。通过软件仿真比较可以看出，该算法实现了信道的动态分配，减小了平均端到端时延，增加了网络平均吞吐量，显著提高了多接口多信道VANET的网络性能。...

| Notes | 51-1196/TP In order to achieve reasonable dynamic allocation of communication channels between the vehicle nodes in multi-ra- dio multi-channel VANET, this paper proposed a dynamic： channel allocation algorithm based on channel switching queue be- tween two communication vehicle nodes. It defined the radio status of vehicle node, proposed the channel performance factor and the generating method of the channel switching queue. By comprehensive considering the radio status and channel switc- hing queue of the both sides of communication vehicle nodes, it established communication links fast independently. It solved the channel fair access and unreasonable allocation. Through software simulation, this algorithm reduces the average end-to- end delay, increases the network average throughput and significantly improves the network performance of multi-radio multi- channel VANET.
