Fast and Reliable Burst Data Transmission for Backscatter Communications

Area of Science:

• Electrical Engineering
• Computer Science
• Wireless Communication

Background:

• Computational radio frequency identification (CRFID) sensors transmit large data volumes wirelessly.
• Existing EPC C1G2 protocols struggle with efficient transmission of critical/emergency data and adapting to dynamic energy/channel conditions.

Purpose of the Study:

• To propose a fast and reliable method for burst data transmission in CRFID systems.
• To optimize the EPC C1G2 communication procedure for critical and emergency data.
• To improve system adaptability to energy-harvesting and channel variations.

Main Methods:

• Data packet fragmentation into blocks for burst transmission.
• Implementation of a burst transmission mechanism within the EPC C1G2 protocol.
• Utilization of erasure codes to minimize Acknowledgement (ACK) delay and enhance reliability.

Main Results:

• The proposed scheme significantly outperforms fixed frame length and DFCA methods.
• Achieved goodput approaches the theoretical optimum across diverse energy-harvesting and channel conditions.
• Demonstrated improved reliability and reduced ACK delay through erasure codes.

Conclusions:

• The novel burst transmission mechanism enhances EPC C1G2 communication for critical data.
• The proposed method offers superior performance and adaptability compared to existing approaches.
• Erasure codes are effective in improving system reliability and reducing communication latency.
