When WiSeNeT is run on a packet radio, it generates all the required components and integrates them together into a single program as shown in Figure 2. In order to test a network of packet radios, it is recommended to connect them all to a single computer, and to run WiSeNeT across multiple terminal sessions on multiple radios. At least one radio must be designated as the sink, and at least one radio must be designated as the source. Routing is optional, however by default it is turned off. If no arguments are specified at the command line, notable default values are:

  • Default to sink if no other application layer program is chosen
  • Link layer data packet send rate: 8 packets/second (must always be greater than zero)
  • Application layer frame generation rate: 8 packets/second (must always be greater than zero)
  • Application layer data length: 16 bytes
  • Application layer number of packets to generate: 40 packets
  • Convergence Sub-layer symbolisation: Deactivated
  • Convergence Sub-layer prologues not added.
WiSeNeT can be run from the command line (terminal window) or run through script files. Because of the way the code is structured, it is a simple process either way. Command line is recommended if the goal is a relatively quick test. Script files, which can be programmed in (Bash) shell or Python, is recommended for more complex scenarios.

As a guide when running the testbed, with a single source sending to a single sink, maximum throughput is approximately 13-15 packets/second with a 16 byte data (application layer frame) size.
