VisualSensor: Modeling of Wireless Sensor Networks

This project supports advanced modeling of communication and sensor channels, ad-hoc networking protocols, and energy consumption. It enables component-based definition of network nodes and channel models for sharing among the research community. Based on Ptolemy II, includes open-source model structure for sensors and channel communication handling. WirelessDirector facilitates model execution and visual representations. Java code or hierarchical Ptolemy models can define sensors.

  1. VisualSensor: Modeling of Wireless Sensor Networks Yang Zhao Graduate Student UC Berkeley

  2. 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

  3. 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
