Abstract

Nowadays, Internet of Vehicles (IoV) is an emerging new technology that allows smart automobiles to communicate while traveling at high speeds via cloud platform and wireless access technologies. It arose from the concept of creating a vehicular ad hoc network (VANET) integrated with Internet of Things (IoT) to achieve specific applications, such as Intelligent Transport System (ITS) and smart cities. Therefore, IoV introduces a smart version of Vehicular Communication System (VCS) that vehicles and Road Side Units (RSUs) are essentially used for communication on highways and in urban cities. This study investigates the communication performance of the static Road Side Unit (RSU) which acts as an important component of IoV/VCS system in urban environment. A DSRC/WAVE stack mechanism is considered for beaconing and channel switching between CCH and SCH of control and service channels. Here, RSU also manages the Wave Short Messages (WSMs) and periodic beaconing, which are used to send WAVE service announcements. The simulation has been verified via implementing one RSU in urban city to evaluate the quality metrics of its communication mechanisms with vehicles nodes in terms of packet deliver rate (PDR), throughput, busy time and Signal-to-Noise Plus Interference Ratio (SNIR) lost packets. The results are obtained using OMNeT++ joined with Veins framework to make intercommunication with SUMO traffic road simulator.
