Primary path reservation using enhanced slot assignment in TDMA for session admission

Area of Science:

• Computer Science
• Networking

Background:

• Mobile ad hoc networks (MANET) operate without infrastructure, posing challenges for Quality of Service (QoS) delivery.
• QoS is critical for real-time applications but is hindered by wireless link unreliability, node mobility, and lack of centralized control.
• Existing QoS mechanisms often focus solely on either reservation or admission control, limiting their effectiveness.

Purpose of the Study:

• To propose a novel framework, PRAC (primary path reservation admission control protocol), to improve QoS in MANETs.
• To address the limitations of current QoS mechanisms by integrating backup routes with resource reservation.
• To enhance the effectiveness of admission control in MANETs, particularly under high mobility conditions.

Main Methods:

• Developed the PRAC framework, incorporating backup routes and resource reservation.
• Simulated a network topology to evaluate the proposed PRAC protocol.
• Focused on improving slot reservation procedures within a TDMA-based system.

Main Results:

• The PRAC framework demonstrates improved QoS by effectively admitting sessions.
• The combination of backup routes and resource reservation enhances admission control performance.
• The proposed mechanism proves effective in managing QoS sessions despite network dynamics.

Conclusions:

• PRAC offers a robust solution for achieving improved QoS in MANETs.
• The integration of backup routes and resource reservation is a key factor in PRAC's success.
• The proposed framework effectively admits QoS sessions, outperforming existing approaches.
