Area of Science:

• Computer Science
• Electrical Engineering
• Network Engineering

Background:

• Wireless sensor networks (WSNs) require efficient synchronization due to their decentralized nature.
• Existing synchronization methods often suffer from high energy consumption due to idle listening.
• Decentralized structures in WSNs pose challenges for maintaining network coherence.

Purpose of the Study:

• To propose an energy-efficient pulse-coupled synchronization strategy for WSNs.
• To reduce the overall energy consumption during the synchronization process.
• To ensure robust and reliable network operation through topology control.

Main Methods:

• Implemented a pulse-coupled synchronization strategy with an extended refractory period to reduce idle listening.
• Developed a decentralized topology control approach to ensure a k-edge strongly connected network.
• Validated the strategy's effectiveness using QualNet simulations.

Main Results:

• The proposed strategy significantly reduces energy consumption by minimizing idle listening.
• The large refractory period does not negatively impact synchronization time.
• The decentralized topology control ensures network resilience against communication link failures.
• The synchronization strategy is effective in both static and mobile WSNs.

Conclusions:

• The energy-efficient pulse-coupled synchronization strategy offers a viable solution for WSNs.
• Decentralized topology control enhances network robustness and adaptability.
• The approach is suitable for mobile and dynamic wireless sensor network environments.
