Vehicular ad hoc networks (VANETs) is a kind of mobile communication in which the vehicles are considered as notes and it includes certain wireless routers. In recent times an increased number of vehicles create a traffic congestion problem in urban enrollment. In recent scientific research to normalize the communication issues of the vehicles, unmanned aerial vehicles (UAVs) are embedded with the vehicular communication mainly to control the traffic congestion and insufficient bandwidth utilization of the vehicles. The aerial vehicles are highly flexible and efficient so that they are able to control the vehicles in an efficient manner. But still certain drawbacks are present in the aerial vehicles such as improper localization and ineffective data transmission. To solve these flaws, in this article reliable data transmission and efficient vehicle path planning in the cooperative communication model (RDTEVP) is developed. The core modules of this model are reliability base network modeling and path planning based routing. Through this process the efficiency of the network is maximized and the data transmission quality is improvised. This model is structured in the software called NS3 parameters which are taken into consideration to analyses the device performance are packet delivery ratio, network throughput, energy efficiency, average delay and routing overhead. The term delay and routing overhead are greatly minimized in the RDTEVP when compared with the earlier schemes.
