A Study on Energy-Efficient Communication in VANETs Using Cellular IoT

Abstract

Vehicular ad hoc networks (VANETs) are formed for safety message propagations in a traffic model. VANETs are specialized mobile ad hoc networks (MANETs). They generally use architecture where vehicles can communicate within them and also through road side units (RSUs). Vehicles in a VANET form and communicate within a cluster. Messages sent from one vehicle may reach each vehicle in multiple hops. As the vehicle density increases vehicles can carry and forward message packets to neighbors easily but it introduces more energy consumption, delay and packet duplication. Using cellular IoT we are attempting to make clusters of vehicles fixed to a cellular tower. This will simplify the architecture of VANET and communication, so that it will reduce the delay and energy consumption, and packet delivery will remain the same for all densities of traffic.
