The figures in the following show the mass probability density of the localizzation error, when the bayesian approach is used. This method is described in the pape Savazzi & all; “Radio Imaging by Cooperative Wireless Network: Localizzation Algorithms and Experiments”; IEEE Int. Conf. WCNC 2012.
Scenario C40
In the following table, the Localizzation Error is misured by the bayesian approach by the a-posteriori probability density, based on a gaussian model.
| Scenario | Parameters | Anchor positions | Error Distribution | Metrics | Notes and video |
|---|---|---|---|---|---|
| C 40 | area: 6.4 X 4.5 [m] anchors: 25 speed: 0.5[step/s] channels: 1 origin: WnLab |  |  | RMSE: 0.867 [m] 75th pc: 0.881 [m] 90th pc: 1.225 [m] | Error distribution in [0.8, 1] m. c40_25sen_1p_1sec.avi |
Scenario Pat_2
IIn the following table, the Localizzation Error is misured by the bayesian approach by the a-posteriori probability density, based on a gaussian model.
| Scenario | Parameters | Anchor positions | Error Distribution | Metrics | Notes and video |
|---|---|---|---|---|---|
| Pat_2 | area: 7 X 7 [m] anchors: 28 speed: 1[step/s] channels: 1 origin: SPAN Lab |  |  | RMSE: 0.867 [m] 75th pc: 0.881 [m] 90th pc: 1.225 [m] | Error distribution in [0.8, 1] m. c40_25sen_1p_1sec.avi |
