摘要 综述了在车载自组织网络(VANET)领域中802.11无线技术自身的不足和可以改进的方法,讨论了改变竞争窗口、设定访问类别等实现差异化服务的技术手段,以及降低潜在信道访问冲突与减少服务延迟之间的关系,指出了802.11系列规范应用于车载网络环境时仍需要进一步研究的方向. The most important part of the researches on 802.11 wireless technology for VANET and their achievement are summarized, and the shortcomings of 802.11 specifications family are focused, some schemes for overcoming these problems are also discussed. Some approaches, such as changing contention windows or setting access categories, are discussed to support service differentiation. The relationship between mitigating channel collisions and reducing service delays is also evaluated, and several further research areas using 802.11 in VANET are mentioned.
