摘要

车辆自组织网络(vanet)通用路由方案的性能受到路由所依赖的特定介质访问控制方案的特性和移动场景的高度影响。在这项工作中，我们通过关注MAC层对路由策略性能的影响，解决了基于位置的路由解决方案的设计，以支持vanet中面向安全的应用。也就是说，我们提出了一个真实的公路移动场景的仿真分析，以评估在标准IEEE 802.11技术和动态TDMA方案分别在第二层采用的两种情况下的路由性能。我们讨论了这两种情况下路由参数的尺寸，并对两种MAC/路由集成解决方案进行了比较分析

Directional broadcast forwarding of alarm messages in VANETs

The performance of general routing schemes for vehicular ad hoc networks (VANETs) is highly affected by the features of the specific medium access control scheme the routing relies upon and by the mobility scenario. In this work, we address the design of position based routing solutions for the support of safety oriented applications in VANETs by focusing on the impact of the MAC layer on the performances of the routing strategies. Namely, we propose a simulation analysis in a realistic highway mobility scenario to assess the routing performance in the two cases where standard IEEE 802.11 technology and a dynamic TDMA scheme are adopted at layer 2 respectively. We discuss on the dimensioning of the routing parameters in both cases and we provide a comparative analysis of the two MAC/routing integrated solutions
