Changes performed in the 6Tisch simulator

added changes by Esteban Municio [email protected]

Scope

See README_initVersion.md Some functionalities have been added:

• Multi-channel full duplex communication

• Possibility to use an ideal phy

• Fix some assumptions for interference

• Fix some bugs when adding/removing cells

• Otf enable/disable. When disabled, an ideal scheduler calculate the number of cells per node. For this perform:

  • Calculation of children nodes
  • Calculation of theoretical demand

• Schedulers:

  • none(otf-sf0): Randomly selects the demanding cells
  • cen: Theoretically avoid collisions by having complete real information in all nodes
  • opt2: Theoretically avoid collisions by having complete real information in all nodes. Optimizes and allow overlapping when no collisions will occur
  • BeBraS: Send EB Broadcast messages in order to locally spread scheduling information. Used cells in the neighborhood are avoided.

• Switch between star and mesh topology

• New Parser file

Running

• Run a simulation: python runSimAllCPUs.py $nodes $scheduler $numBr $numOverlap $rpl $otf $sixtop

$nodes = number of nodes $scheduler = cen | opt2 | none | deBras $numBr = number of broadcast cells per channel $numOverlap = 0 $rpl = RPL DIO period $otf = OTF HouseKeeping Period $sixtop = 6Top HouseKeeping Period

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
