中文摘要: |
车载自组织网络(VANET),通过车间(Vehicle-to-Vehicle,V2V)主动交互安全信息,提高驾驶安全性。分簇是管理车间信息交互,提高网络性能的有效方法。本文以城市交通场景为背景,提出一种相对稳定的分簇算法,并在分簇的基础上,利用车联网多信道的特点,针对安全信息的传输特点和作用范围提出一种多信道安全信息传输机制。簇内通信使用非竞争的TDMA机制,簇间通信使用基于竞争的CSMA/CA机制。仿真实验表明提出的分簇算法以及通信机制能有效提高安全信息的传输性能。 |

VANET, through the Vehicle-to-Vehicle (V2V) communication mode interactive security message to improve road safety. Clustering Clustering is an effective way to manage vehicle information interaction and improve scalability of networking protocols. A relatively stable clustering algorithm is proposed for urban city scenarios. On the basis of clustering, a multi-channel MAC layer protocol is proposed according to the transmission characteristics and scope of security information, taking advantage of the characteristics of multi-channel in vehicular network. The non-competitive TDMA scheme was taken for intra-cluster communications, while the competitive CSMA/CA scheme was taken for inter-cluster communications. The simulation results show that the proposed clustering algorithm and communication protocol can effectively improve the transmission performance of security information. |
