Optimization of Random Early Detection in VANETs

VANETs are designed to enable vehicles to communicate with each other and with roadside units (RSUs) to create efficient, reliable, and smart transport systems.

The two modes of communication in a VANET network are Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication.

Challenges in VANETs include traffic scenarios, road conditions, traffic density, and improper connections causing congestion.

ITS stands for Intelligent Transport System in the context of VANETs.

RSUs, or roadside units, are located at critical points of the road and enable vehicles to communicate with the infrastructure, facilitating V2I communication.

Random Early Detection (RED) is a congestion control mechanism used in VANETs to prevent network congestion by randomly dropping packets before the network becomes congested. It operates by monitoring the average queue size and dropping packets probabilistically based on predefined thresholds.

Vehicle-to-Infrastructure (V2I) communication in VANET networks is significant as it enables vehicles to communicate with roadside units (RSUs) or base stations. This communication mode provides access to important information such as traffic updates, road conditions, and other relevant data necessary for efficient and safe driving.

Some of the challenges associated with VANETs include dynamic traffic scenarios, varying road conditions, fluctuating traffic density, and maintaining reliable connections between vehicles and RSUs. These factors contribute to potential congestion and communication issues within VANET networks.

The primary function of Roadside Units (RSUs) in a VANET network is to facilitate communication between vehicles and the infrastructure. RSUs serve as access points for vehicles to connect to the network, enabling the exchange of information related to traffic, road conditions, and other relevant data.

VANET technology contributes to the development of efficient and reliable transport systems by enabling vehicles to communicate with each other and with infrastructure components such as RSUs. This communication allows for real-time exchange of information, leading to improved traffic management, enhanced safety, and overall optimization of transport systems.
