基于802.11p/WAVE的车联网连通性模型及其应用研究
Study on the connectivity model of VANET based on 802.11p/WAVE and its application
摘要
Abstract
Firstly, a vehicular mobility model was proposed for the freeway traffic scenarios. Then the connectivity para-meters of VANET, such as the connected probability between any two cars, the diameter size of connected cluster and the number of connected cluster, were analyzed. And on the basis of these, the conclusion that the location of VANET node at one time snapshot meets the gamma distribution was drawn. Furthermore, a VANET message package format considering flooding message number was designed, in which TTL field was discussed in detail by introducing the analytic expres-sion of connectivity model. Finally, simulations also verify the conclusion. The connectivity model proposed should pro-vide an important theoretical basis for the upper-level protocols of VANET WAVE stack.关键词
