Modeling the Trade-off Between Throughput and Reliability in Bluetooth Low Energy Connections Under Interference

Q: How can the proposed models be extended to consider the impact of other wireless technologies, such as Wi-Fi, coexisting in the 2.4 GHz band

The proposed models can be extended to consider the impact of other wireless technologies, such as Wi-Fi, coexisting in the 2.4 GHz band by incorporating additional parameters and variables into the existing models. One approach could be to introduce a parameter that represents the presence and activity of Wi-Fi devices in the same frequency band. This parameter could influence the interference levels experienced by the BLE devices and impact their throughput and reliability. By including this parameter in the models, the interactions between BLE and Wi-Fi transmissions can be analyzed more comprehensively. Furthermore, the models can be modified to account for the specific characteristics of Wi-Fi interference, such as the channel utilization, signal strength, and packet collision probabilities. By integrating these factors into the models, a more accurate representation of the coexistence of BLE and Wi-Fi in the 2.4 GHz band can be achieved.

บทคัดย่อ

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.

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.
