Speedy routing recovery protocol for large failure tolerance in wireless sensor networks

Area of Science:

• Wireless Sensor Networks
• Network Routing Protocols
• Fault Tolerance in Networks

Background:

• Wireless sensor networks (WSNs) are crucial for data collection in hazardous environments.
• Physical fragility of sensor nodes leads to routing difficulties, especially during large-scale failures.
• Existing protocols struggle with rapid recovery from extensive node damage.

Purpose of the Study:

• To propose a novel routing protocol, Adaptive Routing Protocol for fast Recovery from large-scale Failure (ARF).
• To enhance network resilience and enable quick recovery from large-area node failures in WSNs.
• To reduce packet and energy consumption during failure recovery.

Main Methods:

• ARF detects node failures by monitoring packet loss from parent nodes.
• Upon failure detection, ARF reduces the routing interval to alert neighboring nodes.
• The protocol facilitates rapid network reconvergence after significant disruptions.

Main Results:

• ARF demonstrates swift recovery from large-area failures.
• The protocol achieves faster recovery compared to existing methods.
• ARF exhibits lower packet and energy consumption during the recovery process.

Conclusions:

• ARF effectively addresses the challenge of large-scale node failures in WSNs.
• The proposed protocol offers a more robust and efficient solution for routing in hazardous environments.
• ARF improves network reliability and extends operational lifespan through optimized recovery mechanisms.
