A Novel Energy-Efficient Reservation System for Edge Computing in 6G Vehicular Ad Hoc Network

Area of Science:

• Vehicular Ad Hoc Networks (VANETs)
• 6G Edge Computing
• Wireless Communication Systems

Background:

• Static roadside units (sRSUs) in VANETs face challenges like high deployment costs, sparse distribution, and communication interruptions.
• Existing research on sRSUs focuses on improving vehicle-to-infrastructure (V2I) communication, but limitations persist.
• The need for more efficient and reliable V2I communication is critical for advanced VANET applications.

Purpose of the Study:

• To propose and evaluate the mobile roadside unit (mRSU) as an emerging concept for 6G VANETs.
• To introduce a novel energy-efficient reservation technique for edge computing utilizing mRSUs.
• To enhance V2I communication connectivity and efficiency in edge computing environments.

Main Methods:

• Development of a reservation-based technique for mRSUs in 6G VANET edge computing.
• Simulation of mRSU performance against sRSU using diverse propagation models.
• Testing across realistic urban scenarios with varying packet sizes and vehicle densities.

Main Results:

• mRSUs demonstrated superior performance over sRSUs, with a 7.7% improvement in packet delivery ratio.
• Throughput increased by 5.1%, end-to-end delay decreased by 4.4%, and hop count reduced by 8.7%.
• A 2% increase in energy consumption was observed due to enhanced performance and connectivity.

Conclusions:

• The mRSU concept offers a significant improvement in V2I communication for 6G VANETs.
• The proposed energy-efficient reservation technique provides a cost-effective and efficient solution.
• mRSUs present a promising advancement for edge computing in future vehicular networks, despite a slight increase in energy use.
