Abstract:




  Vehicles with powerful 
  computing and communications abilities can act as a mobile sensor network for 
  an intelligent transportation system (ITS). Indeed, the timely and reliable 
  delivery of the messages in this network constitute key objectives for an ITS 
  service provider to achieve. In this research, we address the relation between 
  message delivery delay and reliability for the communication between a vehicle 
  and a road side unit (RSU). We focus on sparse or low density vehicular ad hoc 
  networks (VANETs), where timely message delivery and reliable transmission are 
  of special importance. We present an exact message delivery delay distribution 
  for a two-lane road, where vehicles in one direction act as message carriers 
  for the ones in the other direction and have the freedom to leave the road 
  from randomly distributed exits with a certain probability. Our analysis 
  offers a tool for an ITS provider to determine the minimal separation between 
  two consecutive RSUs for meeting a probabilistic requirement of the message 
  delay. Simulation results show the accuracy of our analysis.
