The efficiency of routing protocols in general mobile ad hoc networks may be highly affected by the
specific Medium Access Control scheme the routing relies upon and by the mobility of the wireless
nodes. In this work, we address the design of position based routing solutions for the support of
safety oriented applications in Vehicular Ad hoc NETworks (VANETs) by focusing on the impact of
the MAC layer on the performances of the routing strategies. Namely, we propose a simulation
analysis in highway scenarios 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.
