Enhanced Multicast Repair Fast Reroute Mechanism for Smart Sensors IoT and Network Infrastructure

Area of Science:

• Computer Science
• Network Engineering
• Internet of Things (IoT)

Background:

• Internet of Things (IoT) networks require robust management and reliability due to their sprawling nature.
• Modern Internet Protocol (IP) networks necessitate minimal packet loss and efficient network convergence after failures.
• Existing Fast ReRoute (FRR) mechanisms often rely on pre-calculated backup paths, which can be inflexible.

Purpose of the Study:

• To present an novel Fast ReRoute (FRR) mechanism, the Enhanced Multicast Repair (EM-REP).
• To address the limitations of pre-computation in current FRR solutions.
• To enhance network reliability and minimize packet loss in IoT environments.

Main Methods:

• Development of the Enhanced Multicast Repair (EM-REP) mechanism.
• Utilizing multicast technology to establish alternative backup paths reactively.
• Avoiding the need for pre-calculation of backup routes.

Main Results:

• The EM-REP mechanism demonstrates a unique reactive behavior in Fast ReRoute.
• It effectively finds alternative paths even with multiple, time-disparate link or node failures.
• The mechanism is suitable for IoT sensor networks demanding high data transfer reliability.

Conclusions:

• The EM-REP FRR mechanism provides a novel, reactive approach to network recovery.
• Its ability to handle multiple failures without pre-calculation enhances network resilience.
• This approach is particularly beneficial for ensuring reliable data transfer in IoT sensor networks.
