Summary
Environmental factors significantly impact wireless Received Signal Strength Indicator (RSSI) prediction. An adaptive machine learning model incorporating these factors improves accuracy, outperforming traditional methods for better network planning and performance.
Area of Science:
- Wireless Communications
- Machine Learning
- Environmental Sensing
Background:
- Received Signal Strength Indicator (RSSI) prediction is vital for network planning, optimization, and efficient handover management.
- Traditional path loss models offer a theoretical basis but struggle with complex environmental interactions.
- Machine learning presents a data-driven approach to enhance wireless network performance.
Purpose of the Study:
- To propose an adaptive machine learning framework for RSSI prediction.
- To integrate environmental sensing parameters (temperature, humidity, pressure, particulate matter) into RSSI prediction.
- To evaluate the impact of environmental factors on RSSI prediction accuracy.
Main Methods:
- Developed an adaptive machine learning framework for RSSI prediction.
- Incorporated environmental sensing data (temperature, relative humidity, barometric pressure, particulate matter).
- Compared the proposed model against baseline models using performance metrics like variance explained and root mean squared error.
Main Results:
- RSSI values are influenced by environmental factors through complex, non-linear interactions.
- The proposed model showed a 6.02% increase in variance explained compared to a baseline model without environmental data.
- A 2.04% increase in variance explained and a reduction in root mean squared error to 1.40 dB were observed when including environmental parameters.
Conclusions:
- Environmental factors significantly impact RSSI prediction, challenging linear assumptions of traditional models.
- Cognitive methods integrating environmental data substantially enhance RSSI prediction accuracy.
- The proposed framework offers improved accuracy for wireless network planning and optimization.
