| # HubEdgeLoc Dataset |
|
|
| [](#) |
|
|
| This repository contains the official dataset for the IMWUT paper **"HubEdgeLoc: Edge-Based Temporally Robust Real-Time Localization for Mobile Assets in Transport Hubs."** |
|
|
| HubEdgeLoc is a longitudinal Wi-Fi received signal strength (RSS) dataset collected for evaluating indoor localization methods and their robustness to environmental and access-point changes over time. |
|
|
| ## Dataset Highlights |
|
|
| - **Longitudinal data:** Five monthly evaluation sets are provided for the airport and two for the campus. |
| - **Two scenarios:** The dataset covers a large, dynamic airport terminal and a more structured university campus environment. |
| - **Multiple fingerprint representations:** Each scenario includes the original observations, a traditional representation, and the compact Score/Top-K representation used by HubEdgeLoc. |
|
|

| |-- Month1/ |
| `-- Month2/ |
| ``` |
|
|
| Each `MonthX` directory follows the same two-file organization as `Init`: an `RSS_dat*.csv` file containing Wi-Fi observations and a `postest.csv` file containing local-coordinate data. |
|
|
| ## Fingerprint Database |
|
|
| The `Fingerprint Database` directory contains the reference data used to construct the radio map in three forms: |
|
|
| - **Original data:** `RSSOridat.csv` stores the grouped Wi-Fi RSS observations. |
| - **Traditional representation:** `Traditional Process Dat.csv` stores the conventional high-dimensional fingerprint representation. |
| - **Score/Top-K representation:** `Macnumtrain.csv` stores the AP identifier mapping, `postrain.csv` stores reference coordinates, the `TopKnumMactrain.csv` or `ToPKnumMactrain.csv` file stores the selected AP indices, and `TopKRSStrain.csv` stores their RSS values. |
|
|
| ## Temporal Evaluation Sets |
|
|
| - **`Init/`:** Data collected immediately after construction of the fingerprint database. |
| - **`Month1/` to `MonthX/`:** Independent data collected in subsequent months for evaluating temporal robustness. The airport contains Month1 through Month5, while the campus contains Month1 and Month2. |
|
|
| The MAC-like values in the published files are privacy-preserving virtual identifiers rather than the original hardware addresses. |
