VEHICLE Speed and Acceleration Control in a VANET simulation (Four legs intersection case study)

Vehicular Ad-Hoc Networks (VANETs) are a specialized form of ad-hoc networks that enable communication between automobiles and also between vehicles and roadside infrastructure. The speed parameter is significant in multiple aspects of VANET design and applications and it denotes the rate at which vehicles move inside the network. The goal of this paper is to achieve different levels of the speed and study their influence on different parameters of vehicles’ network especially in beacon message transmissions. Another aspect is how the speed is related to the load channel. In other words, the main aim consists on adapting the traffic simulation to the reality as close as possible, specifically to find how can we adapt the simulation speed to real vehicle speed. An important element in this effort was the control on the speed and acceleration of the vehicles. Beside this, we concluded the influence of the speed on the communication between vehicles in a VANET simulation, considering specifically the BSM messages and beacon interval. And as the result of these simulations, there is a relation between the speed and the network features, and a relation between combination of speed and channel load to network properties. The goal of simulations after all, was to serve as e pre-envision when this network will be implemented in reality. The future is promising when considering these vehicle networks.
