Performance Evaluation for Trust and Mobility Modeling with Emergency Communications in UAVs Assisted VANETs
Аннотация
In recent years, communication has emerged and occupies lots of applications of intelligent communication. Due to high-speed vehicles, lots of issues are created in the network, such as high delay, high power consumption, and overhead. To overcome such drawbacks in vehicular communication, unmanned aerial vehicles (UAVs) are developed. This technology is highly suitable for managing the vehicles that are in remote areas. The UAVs are highly flexible so that it is able to monitor the frequently changing topologies of the vehicles in a periodical manner. At the time of confidential data transmission, this technology suffers from certain issues like link failures in a continuous manner so that the confidential data gets loss at the time of data transmission. To neglect such drawbacks, the evaluation of trust and mobility modeling with emergency communication in aerial vehicles (PTMEC-UAV) is developed. The core modules that are present in this model are trust evaluations with direct and indirect nature, effective mobility construction of the aerial vehicles, and intelligent mobility production-based routing protocols are present. As a whole, this model attends better performance in terms of efficiency. The system is implemented in the software NS3, and the parameters concentrated to analyze the network activities, such as packet delivery ratio, network throughput, average delay, energy efficiency, and routing overhead. From the result and discussion, it is proven that PTMEC-UAV attains better results concerned with the parameters like efficiency and delivery ratio than the earlier research models.
