Experimental Analysis of Broadcast Reliability in Dense Vehicular Networks
Abstract—Dedicated Short Range Communications (DSRC)based communications enable novel automotive safety applications such as an Extended Electronic Brake Light or Intersection Collision Avoidance. These applications require reliable wireless communications even in scenarios with very high vehicle density, where these networks are primarily interference-limited. Given the uncertainties associated with current simulation models, particularly their interference models, it is critical to experimentally validate network performance for such scenarios. Towards this goal, we present a systematic, large-scale experimental study of packet delivery rates in a dense environment of 802.11 transmitters. We show that even with 100 transmitters in communication range with a frame size of 128 bytes and a bit-rate of 6Mbps, (a) most receivers can decode over 1500 pps in a saturated network, which corresponds to a packet delivery rate of 45% and (b) the mean packet delivery rate, for 10 pps per node w...
