A Survey on Proactive, Active and Passive Fault Diagnosis Protocols for WSNs: Network Operation Perspective

Area of Science:

• Computer Science
• Network Engineering
• Telecommunications

Background:

• Wireless sensor networks (WSNs) are widely researched, yet fault diagnosis remains a neglected area.
• WSNs require robust fault diagnosis due to their ad-hoc nature, deployment constraints, and limited resources.

Purpose of the Study:

• To provide a comprehensive survey of fault diagnosis schemes in WSNs from a network operations perspective.
• To analyze the advantages and limitations of various fault diagnosis approaches.

Main Methods:

• Systematic review of existing literature on fault diagnosis in WSNs.
• Categorization of fault diagnosis schemes into proactive, active, and passive approaches.
• Analysis of each scheme's operational aspects, benefits, and drawbacks.

Main Results:

• Identified a gap in research concerning fault diagnosis in WSNs.
• Detailed the landscape of proactive, active, and passive fault diagnosis techniques.
• Highlighted the specific challenges and considerations for fault diagnosis in WSNs.

Conclusions:

• Fault diagnosis is an essential but underdeveloped aspect of WSNs.
• The survey provides a foundation for understanding current methods and identifies critical areas for future research.
• Further investigation into WSN fault diagnosis is needed to enhance network reliability and performance.
