Wifi Positioning

This program is a simple wifi positioning demo, which uses WKNN (Weighted K-Nearest-Neighbor) algorithm. The repo also provides a wifi dataset in the data directory.

1. Prerequisites

This program has been tested on Ubuntu 16.04. It has several dependecies.

1.1 Mlpack

You can simply install mlpack with the following command:

sudo apt-get install libmlpack-dev

But this may not have the most recent version of mlpack available. Or you can follow mlpack installation if you want to install with a manual build.

1.2 Eigen

You can simply install Eigen with the following command:

sudo apt-get install libeigen3-dev

1.3 OpenCV (optional)

OpenCV is used to visualize the wifi positioning results. This library is optional.

2. Build

Clone the repository and build:

git clone https://github.com/gjgjh/WifiPositioning
cd ~/WifiPositioning
mkdir build
cd build
cmake ..
make -j4

3. Example

We provide a read wifi dataset in the data directory. The data was collected on the fourth floor of the Science Academic Building of Peking University, and the collection equipment was an ASUS computer. The detailed file format is here. A simple usage example can be found in the test directory.

4. License

The source code is released under GPLv3 license.

We are still working on improving the code reliability. For any technical issues or commercial inquiries, please contact GJH guojh_rs@pku.edu.cn.
