This repository includes:

1. The Whisper controller
   • Algorithms for translating Policies to Primitives.
   • Local Whisper Controller that runs in Openvisualizer.
   • Coap repository.
   • Sample topologies to test the switch-parent algorithm.
   • Misc tools.
2. Current OpenWSN firmware:
   • Current original OpenWSN firmware for the normal nodes (updated 10 Dec 2019).
3. Firmware for the Whisper nodes (root and leaf):
   • Modified version of OpenWSN that comunicates with the controller through COAP (leaf) and through serial (root).
4. Monitoring tools:
   • A sniffer for OpenMote that captures traffic from the network.
   • A modified version of Foren6 to process and display information from the captured traffic:
     • Parent relationship (DAOs).
     • Ranks (DIOs).
     • 6TiSCH schedules (6P commands).
5. ONOS framework with including the Whisper module:
   • Whisper provider.
   • Whisper protocol (southband).
   • Whisper App (GUI+CLI)
     • 6TiSCH Topology Component
     • 6TiSCH schedules UI Component
     • Whisper Controllers UI Table Components

Supports:

---

• Parent switching through DIOs
• Schedule modification through 6P commands (e.g. to allocate cells before the parent switch or 6P List)
• Monitoring capabilities:
  • Neighbors of the Whisper node
  • Logic and physical topology
• Orchestration from ONOS via edge metrics and intents.
