Overview

• Supports sophisticated modeling of
• communication channels, sensor channels
• ad-hoc networking protocols
• media access control protocols
• localization strategies
• energy consumption in sensor nodes
• Supports Component-based definition of network
  nodes and channel models
• Intended to enable the research community to
  share models of disjoint aspects of the sensor
  nets problem
• Based on Ptolemy II, composable with other models
  of computation from Ptolemy II
• Open source

Model Structure

• Sensors are modeled by actor components, can be
  defined using Java code or hierarchical Ptolemy
  models.
• Channel models handle communication between the
  actors
• Sophisticated channel components can be developed
  to model package loss, propagation delay, power
  loss, terrain effects etc.
• WirelessDirector mediates the model execution
• Support visual representations of sensor nodes
  and animation of sensing, node mobility, etc
