A Comparison of Alternative Distributed Dynamic Cluster Formation Techniques for Industrial Wireless Sensor Networks

Area of Science:

• Computer Science
• Electrical Engineering
• Network Engineering

Background:

• Wireless sensor networks (WSNs) are crucial for industrial monitoring and tracking.
• Existing clustering techniques face challenges in dynamic industrial environments.
• Effective cluster management is vital for WSN performance and resource utilization.

Purpose of the Study:

• To develop a novel distributed management approach for tracking mobile nodes in industrial WSNs.
• To objectively compare pre-defined and ad hoc clustering approaches for WSNs.
• To analyze the trade-offs between cost, effectiveness, and reconfigurability in cluster management.

Main Methods:

• Development of a new distributed management strategy for mobile node tracking.
• Comparative analysis of pre-defined versus ad hoc clustering methods.
• Introduction and application of three novel metrics: cost/efficiency, performance, and resource consumption.

Main Results:

• Ad hoc clusters demonstrate superior adaptability to environmental changes in industrial WSNs.
• Pre-defined clusters exhibit higher overall efficiency compared to ad hoc clusters.
• A clear trade-off exists between adaptability and efficiency in WSN cluster management.

Conclusions:

• Ad hoc clustering is more responsive to dynamic industrial sensing environments.
• The choice between pre-defined and ad hoc clustering depends on the specific application's priorities (adaptability vs. efficiency).
• The proposed metrics provide a robust framework for evaluating WSN clustering strategies.
