Project for the course called "Internet of Things" at Politecnico di Milano.

Simulate a WSN composed by 8 fixed anchors and 1 mobile node, which moves along a known path.
The anchors periodically broadcast beacons, which are received by the mobile node. Upon reception, the mobile node estimates the RSSI of the beacons, converts it into distance measures and triangulates its position by using the best three beacons.

1. Create a specific component to simulate RSSI estimation. The component acts as an oracle, knowing the trajectory of the mobile node and the position of all the anchors. Use a log-distance path loss model for power-to-distance conversion, e.g. P = P0 + 10log10(d/d0) + v, with v an additive Gaussian noise of known distance.
2. From the estimated RSSI, retrieve a distance measure (only for the best 3 anchor nodes).
3. Use the Gradient Descent Triangulation techniques to obtain the position of the mobile node.
4. Compute and plot the localization error VS the Gaussian noise variance v.

The plot with the localization error on Y and the Gaussian noise variance on X is:

• 04/05/2015 - IOT Localization 1.0.0 released

• 2 projects in one repository. AnchorNode and MobileNode projects for Eclipse (with Yeti 2 TinyOS plugin).
• Sources
• Binary files ready to use
• Report of the project and the ".csc" simulation's files for Cooja
• Log file

• Test this software on real sensors.

Step 1. Download Instant Contiki VM HERE.
Step 2. In the VM, download the ".zip" file from the page "Releases" of this project.
Step 3. Download in ~/git this source code with: git clone
Step 4. Execute these commands:

    $ cd ~/git/<name of this project>/AnchorNode
    $ mkdir build
    $ cd build
    $ mkdir telosb
    $ cd ~/git/<name of this project>/MobileNode
    $ mkdir build
    $ cd build
    $ mkdir telosb

Step 5. In the downloaded files extracted from the ".zip" copy Binary-files/AnchorNode/main.exe in

    $ cp ~/Downloads/<extracted files folder>/Binary-files/AnchorNode/build/telosb/main.exe ~/git/<name of this project>/AnchorNode/build/telosb/main.exe
    $ cp ~/Downloads/<extracted files folder>/Binary-files/MobileNode/build/telosb/main.exe ~/git/<name of this project>/MobileNode/build/telosb/main.exe

Step 6. Run Cooja with:

    $ cd ~/contiki-2.7/tools/cooja
    $ ant run

Step 7. In Cooja, load the ".csc" file in the released ".zip", and click on the "Start" button to start the simulation.

Step 1. If you want to compile this softwares with Eclipse, download Eclipse C++ HERE.
Step 2. Intall Yeti 2 Plugin, using this "Software Site": http://tos-ide.ethz.ch/update/site.xml
Step 3. Import AnchorNode from the downloaded files in ~/git//AnchorNode in a project
Step 4. Import MobileNode from the downloaded files in ~/git//MobileNode in a different project
Step 5. Initialize the VM to download TinyOS using this tutorial http://tinyprod.net/repos/debian/
Step 6. Download TinyOS using this tutorial http://tinyos.stanford.edu/tinyos-wiki/index.php/Automatic_installation
Step 7. Restart Eclipse, go in Window->Preferences->TinyOS->Environments->TinyOS 2.x unix-environment and set the path of "TinyOS Root Directory"



Step 8. Include "printf.h" in Project->Properties->TinyOS Build->2.Includes and check that ncc=consider and Include=system
Step 9. Include "math.h" in Eclipse only in the MobileNode's project.
