Optimizing vehicular communication strategies is important for an efficient usage of the
available wireless bandwidth and also critical for the success of VANETs. In this paper we
address the fundamental and practical question whether the load on the wireless channel
can be reduced if periodic beacon messages are transmitted over multiple hops with
reduced transmit power instead of being transmitted over one hop with high transmit power.
In particular, we look at the possible bandwidth savings that can be achieved by …
