Local Voting TSCH

Implementation of the Local Voting algorithm in the 6TiSCH Simulator, and some simulation results. Comparison of Local Voting with OTF, thresholds 0,1,4,10, 1,2, and 3 parents, and 10 and 100 buffer size.

You can find eps and png figures of the results in folder bin/simData/

The 6TiSCH Simulator

Scope

6TiSCH is an active IETF standardization working group which defines mechanisms to build and maintain communication schedules in tomorrow's Internet of (Important) Things. This simulator allows you to measure the performance of those different mechanisms under different conditions.

What is simulated:

• protocols
  • IEEE802.15.4e-2012 TSCH (http://standards.ieee.org/getieee802/download/802.15.4e-2012.pdf)
  • RPL (http://tools.ietf.org/html/rfc6550)
  • 6top (http://tools.ietf.org/html/draft-wang-6tisch-6top-sublayer)
  • On-The-Fly scheduling (http://tools.ietf.org/html/draft-dujovne-6tisch-on-the-fly)
• the "Pister-hack" propagation model with collisions
• the energy consumption model taken from
  • A Realistic Energy Consumption Model for TSCH Networks. Xavier Vilajosana, Qin Wang, Fabien Chraim, Thomas Watteyne, Tengfei Chang, Kris Pister. IEEE Sensors, Vol. 14, No. 2, February 2014.

What is not simulated:

• downstream traffic

Installation

• Install Python 2.7
• Clone or download this repository
• To plot the graphs, you need Matplotlib and scipy. On Windows, Anaconda (http://continuum.io/downloads) is a good on-stop-shop.

Running

• Run a simulation: bin/simpleSim/runSim.py
• Plot fancy graphs: bin/simpleSim/plotStuff.py

Use bin/simpleSim/runSim.py --help for a list of simulation parameters. In particular, use --gui for a graphical interface.

Code Organization

• bin/: the script for you to run
• SimEngine/: the simulator
  • Mote.py: Models a 6TiSCH mote running the different standards listed above.
  • Propagation.py: Wireless propagation model.
  • SimEngine.py: Event-driven simulation engine at the core of this simulator.
  • SimSettings.py: Data store for all simulation settings.
  • SimStats.py: Periodically collects statistics and writes those to a file.
  • Topology.py: creates a topology of the motes in the network.
• SimGui/: the graphical user interface to the simulator
