Reliable freestanding position-based routing in highway scenarios.

Area of Science:

• Networking
• Transportation Engineering
• Computer Science

Background:

• Vehicular Ad Hoc Networks (VANETs) promise enhanced driving safety and efficiency.
• Complex networking protocols and high vehicle mobility pose challenges for VANET deployment.
• Existing routing strategies inadequately address highway-specific constraints.

Purpose of the Study:

• To propose a reliable freestanding position-based routing algorithm (FPBR) for highway VANETs.
• To address challenges of vehicle mobility and propagation conditions in highway scenarios.
• To evaluate FPBR's performance against leading highway routing protocols.

Main Methods:

• Developed a novel freestanding position-based routing algorithm (FPBR).
• Designed FPBR with mechanisms to overcome highway-specific constraints like high mobility and signal loss.
• Compared FPBR performance against a leading highway routing protocol under different propagation models.

Main Results:

• FPBR demonstrated comparable performance to existing protocols under free-space conditions.
• FPBR significantly outperformed the leading protocol when a realistic highway path loss model was applied.
• The algorithm effectively manages high vehicle mobility and adverse propagation conditions.

Conclusions:

• FPBR is a robust routing solution for highway VANETs.
• The proposed algorithm offers improved performance in realistic highway environments.
• FPBR contributes to the effective deployment of VANET technology for safer and more efficient driving.
