OpenVisualizer is the primary tool for plugging your OpenWSN network into the Internet.

...

  • Connects your OpenWSN network to the Internet over a virtual interface (both Windows and Linux).
  • portable across popular operating systems.
  • Shows the internal state (neighbor table, scheduling table, queue, etc.) of each node physically connected to the OpenVisualizer.
  • Displays errors reported by motes.
  • can run with either physical motes, or emulated motes (for details, see OpenSim).

Installation

Prerequisites

PackageRoleInstallation Notes
Pythonimplementation languageUsing v2.7. v3.x not supported yet.
PySerialserial to moteUsing v2.6.

PyWin32
Python Extensions for Windows

tunnel dependency
(Windows only)		Using Build 218. Be sure to review README.txt at the download site to retrieve the proper version.
SConstool executionUsing v2.3.
TAP for WindowsIPv6 tunnel driver
(Windows only *)		Using v9.9.2. When selecting components, include TAP Utilities as well as the adapter itself.
The TUN interface on Windows requires some configuration. Follow our tun/tap for Windows tutorial, specifically the Install tun page and the Configure tun page (perform Computer B steps).

FTDI USB/Serial driver

serial to mote
(e.g. TelosB)

 
Silicon Labs CP2102
UART-to-USB bridge		serial to mote
(e.g. GINA)		For Windows, download CP210x VCP Windows driver. Use the default options. If successful, Windows shows two new programs (Control Panel > Programs > Programs and Features):
Silicon Laboratories CP320x USB to UART Bridge (Driver Removal)
Silicon Laboratories CP320x VCP Drivers for Windows XP/2003 Server/Vista/7

* On Linux, TUN/TAP already is included with the operating system, and OpenVisualizer configures it on the fly. See our TUN/TAP in Linux page for more information.

The --trace option provides internal memory profiling of OpenVisualizer itself, and requires yappi.

Download

PackageRoleInstallation Notes
openwsn-swOpenVisualizer softwareDownload zip or clone with Git. Typically, we use the develop branch as our common development base.
openwsn-fwFirmware header files required by openwsn-swDownload zip or clone with Git.
Must install in a sibling directory to openwsn-sw. So, if software is in C:\develop\openwsn-sw, then firmware must be in C:\develop\openwsn-fw.

See the Installation and Dependencies page to download and install OpenVisualizer. The page also describes required libraries and tools.

Running it

The OpenVisualizer consists of core modules, and several types of user interfaces:

...

The following commands are available:

  • TODO TODO

web interface

...

The web interface is

...

 

 provided by a server application, and of course a browser to view the UI. At present, both server and browser must be on the same host computer.

starting

You have two options to start it:

  • double-click on openwsn-sw/software/openvisualizer/bin/openVisualizerApp/openVisualizerWeb.py

  • enter the following command from openwsn-sw/software/openvisualizer/:

    Code Block
    scons runweb

    By default, the server listens on port 8080 on all network interfaces. The command line accepts options for alternate values. Run scons --help for details.

usage

To get started, point your browser to the following URL: http://localhost:8080. The web user interface includes the same information as the GUI described above; however, most of the information is grouped under three tabs. See the screenshot below.

The "motes" dropdown lists all the motes connected to the OpenVisualizer (either physically over a serial port, or as emulated motes):

Info

By default, none of the motes act as the DAG root. The DAGroot (see RFC6550) is the gateway of your OpenWSN network. It is both the root of the routing and synchronization Directed Acyclic Graphs (DAGs). You need exactly one DAGroot in your OpenWSN network, and it can be any OpenWSN node.

From the "motes" top menu, select the mote to be used as a DAG root and the "toggle" button. The other motes will now synchronize to it and form a DAG.
