Abstract

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
