摘要
近几年车载自组织网络在学术界和工业界都发生了巨大的变化。车载网络运用多信道操作模式来提供开放的安全服务和安全有效的驾驶体验,由此可见多信道接入在车载网络中占据非常重要的角色。吞吐量和时延是两个很重要的指标。基于最新标准,提出了基于信道通信间负载均衡和车辆间信道协作的多信道接入机制MCAS。理论分析和仿真结果都表明,MCAS在吞吐量和服务传输时延上都优于WAVE。
The VANET has witted the large change in academia and industry in recent years.VANETs apply multichannel operation mode to provide open safe services and effective driving experience.So the multi- channel access plays an important role in vehicle ad hoc network.There are two vital indexes,those are throughput and delay.Based on the latest standard,we proposed a multi-channel access scheme MCAS, which considers load balance between channel communication and channel coordination between chan- nels.Theory analysis and simulation results show that MCAS is better than the WAVE on the service trans- mission delay and throughput.
