Research on Throughput-Guaranteed MAC Scheduling Policies in Wireless Networks

Area of Science:

• Computer Science
• Electrical Engineering
• Wireless Communication

Background:

• Media Access Control (MAC) scheduling is crucial for wireless networks, with centralized and distributed models.
• Existing MAC scheduling policies can guarantee throughput but often fail to ensure bounded end-to-end average delay.
• Both throughput and delay are critical performance metrics in practical communication networks.

Purpose of the Study:

• To systematically investigate existing MAC scheduling strategies concerning both throughput and delay.
• To analyze the reasons why some throughput-guaranteed schemes do not ensure bounded average delay.
• To provide a theoretical foundation for enhancing MAC scheduling in future wireless networks.

Main Methods:

• Theoretical analysis of MAC scheduling algorithms.
• Performance evaluation through simulation experiments.
• Comparative study of centralized and distributed scheduling approaches.

Main Results:

• Identified limitations in current MAC scheduling schemes regarding delay guarantees.
• Demonstrated the trade-offs between throughput and delay in different scheduling strategies.
• Validated findings through comprehensive theoretical and simulation-based assessments.

Conclusions:

• Current MAC scheduling methods require further refinement to simultaneously optimize throughput and delay.
• A deeper understanding of the throughput-delay relationship is essential for next-generation wireless networks.
• This research offers a foundational framework for developing advanced MAC scheduling technologies.
