The trade-off between throughput and reliability in Bluetooth Low Energy (BLE) connections can be accurately modeled and quantified through mathematical models that are validated by extensive practical experiments.
Resumé
The paper presents a thorough investigation of the trade-off between throughput and reliability in Bluetooth Low Energy (BLE) communications under interference.
First, a mathematical model is derived to predict the throughput of a BLE connection under interference. This throughput model is then linked to a previously developed reliability model. The theoretical results from both models are extensively validated through practical experiments under various scenarios, including different interference conditions and BLE parameter settings.
The validated models are then used to explore the trade-off between throughput and reliability. Pareto curves are drawn to visualize the compromise between these two key performance metrics. The models provide a design-level guideline for BLE usage and deployment, allowing users to quantify the impact of different BLE parameters on throughput and reliability.
The key highlights are:
- A novel mathematical model to predict BLE throughput under interference is derived and validated.
- The throughput model is linked to a previously developed reliability model to explore the trade-off.
- Extensive practical experiments are conducted to validate the accuracy of both the throughput and reliability models.
- Pareto curves are used to illustrate the trade-off between throughput and reliability under different scenarios.
- The models can serve as a design-level guideline for BLE usage and deployment.
Statistik
The packet transmission time of the victim connection (PTV) ranges from 912 μs to 1712 μs, corresponding to a payload size from 100 bytes to 200 bytes.
The packet transmission time of the disturber connection (PTD) is 512 μs with a 50-byte payload.
The connection interval (CID) is set to 7.5 ms for both the victim and disturber connections.
The inter-frame space (IFS) is 150 μs.
Citater
"The similarity between the theoretical results and the experimental ones highlights the accuracy of the proposed throughput and reliability models. Hence, the two models can be used to explore the performance of various BLE designs or deployments from diverse perspectives."
"The significance of the suggested model is to explain the trade-off within BLE communications simply through numbers and formulas. Rather than just providing a rough or general trend, the trade-off and relationships between reliability and throughput are accurately calculated under various scenarios."
