• Abstract:
  Primary research focused on the design and development of an energy-efficient Risk Notification Message Dissemination Protocol (RNMDP) for vehicular ad hoc networks (VANETs). RNMDP propagates Risk Notification Messages (RNMs) from a location of origin to vehicles approaching a Risk Zone. The performance of RNMDP was compared with that of the commonly used flooding strategy through extensive simulations conducted for highway networks with different numbers of lanes and lane density. Simulation results indicate that with a slightly larger delay, RNMDP can achieve the same message delivery ratio attained by flooding, but at a relatively much lower energy loss compared to flooding. RNMDP has been designed to minimize the energy lost in the propagation of the RNMs, but at the same time incur the least possible delay in delivering the messages.
