WSN Simulation Modeling, Emulation and Tiny VMs for WSN nodes

Multi Agent Framework for Self-Organizing Sensor Networks

Presenation: "Visual Simulation Modeling in Ptolemy II"

Work in progress:

• WSN architecture design and application modeling with new algorithms for add-hock networks: amorphus computing, mult-hop routing, gradient-based routing, etc. Models are developed in Ptolemy II (Java-based) simulation environment.
• Modeling ZigBee protocol stack for applications controlling wirelessly networked, reliable, low-power and cost-effective devices.
• Architecture design of Mote VM – tiny virtual machine for WSN node running TinyOS.
• Architrcture design of MEM Net - Mote EMulator Network, that consists of:
  • MEM - Wireless Sensor Node (mote) emulator
  • MEM Net - network of emulated motes.
  Designed with support of TinyOS (open source operating system for WSN from Berkeley) MEM Net will:
  • Allow develop, debug and profile WSN mote software on a host PC.
  • Support virtual mote devices emulated on a host PC.
  • Automatically translate emulated mote software to target mote platform.
  • Emulate different models of radio channels (powerloss, collisions, etc.)
