Table 3. Parameters and Coefficients Used in theProposed QoE Estimation Model
| Parameter | Symbol | Measurement Unit | Influence on QoE | Coefficient (λ) | Weight (δ) |
| Delay | D | milliseconds (ms) | High delay reduces real-time interaction quality (VoIP, video calls). | 0.25 | 0.35 |
| Jitter | J | milliseconds (ms) | Causes video frame distortion and playback inconsistency. | 0.30 | 0.25 |
| Packet Loss | P | percentage (%) | Leads to data corruption and pixelation in streaming. | 0.40 | 0.30 |
| Throughput | T | Mbps | Higher throughput improves smoothness and resolution. | – | 0.10 |
| Error Term | ε | — | Represents model uncertainty or unmeasured factors. | — | — |
