An Energy-Efficien Slotted Sense Multiple Access Broadcast Protocol for Reliable Command Delivery in Dynamic Wireless...

Area of Science:

• Computer Science
• Electrical Engineering
• Network Engineering

Background:

• Wireless sensor networks (WSNs) are crucial for industrial monitoring and control.
• Flooding protocols offer high reliability but suffer from excessive energy consumption.
• Existing protocols like RSBP reduce energy use but compromise reliability in harsh environments and topology changes.

Purpose of the Study:

• To develop a novel protocol for WSNs that balances high reliability and low energy consumption.
• To address the limitations of flooding and RSBP in terms of energy efficiency and robustness.
• To improve message delivery reliability and responsiveness in dynamic network conditions.

Main Methods:

• Proposed a Broadcast Sharable Slot (BSS) approach, allocating slots per tree level for topology independence.
• Nodes within the same level compete for rebroadcasting within the BSS, reintroducing redundancy.
• Implemented slot-scheduled transmissions within BSS to minimize collisions and manage energy precisely.

Main Results:

• The proposed approach demonstrated high reliability comparable to flooding protocols.
• Achieved low energy consumption levels similar to the RSBP protocol.
• Simulations and experiments validated the effectiveness of the BSS strategy.

Conclusions:

• The BSS approach offers a superior trade-off between reliability and energy efficiency in WSNs.
• This method provides a robust and energy-conscious solution for industrial monitoring and control applications.
• The topology-independent BSS scheduling enhances network adaptability and performance.
