Game-Theoretical Design of an Adaptive Distributed Dissemination Protocol for VANETs

Area of Science:

• Computer Science
• Network Engineering
• Transportation Systems

Background:

• Vehicular Ad Hoc Networks (VANETs) are crucial for road safety applications, relying on effective warning message dissemination.
• Data dissemination in VANETs is challenging due to dynamic topologies, varying densities, and intermittent connectivity.

Purpose of the Study:

• To propose a decentralized, adaptive solution for the data dissemination problem in VANETs.
• To address the challenges posed by non-stationarity in VANET environments.

Main Methods:

• Developed two game-theoretical mechanisms for decentralized data dissemination.
• Implemented an adaptive procedure to handle environmental changes and network dynamics.

Main Results:

• The proposed solution significantly reduces the number of transmissions and end-to-end delay.
• Achieved lower network overhead while maintaining a high message delivery ratio.
• Demonstrated superior performance compared to existing data dissemination methods.

Conclusions:

• The decentralized stochastic solution effectively addresses data dissemination challenges in VANETs.
• The adaptive game-theoretical approach enhances the reliability and efficiency of VANETs for road safety.
• This method offers a promising strategy for improving vehicular communication systems.
