Advanced wireleSS Environment Research Testbed (ASSERT)

Formerly Texas Networking Testbed (TNT)

Overview

Advanced wireleSS Environment Research Testbed (ASSERT) is a device-independent platform for developing and testing wireless network protocols in Distributed System laboratory of The University of Texas at Dallas. The system contains hardware and software facilities to conduct wireless experiments that are:

  1. Repeatable
  2. Realistic
  3. Accurate
  4. Cost Effective
  5. Scalable

The testbed is designed to be a device independent platform for conducting wireless experiments. The testbed is provisioned with a basic set of wireless sensor nodes as the Unit Under Test (UUT) for conducting wireless sensor networking experiments. We currently have 40 sites and 25+ Crossbow MICA2 motes for this purpose. If an experimenter does not wish to use this technology, ASSERT allows the UUT to be interchanged with any other wireless device with correct antenna connectors operating in 725MHz to 1125MHz.

If UUTs are capable of interacting with interfaces such as RS-232, ASSERT can extend it's operation by relaying user commands to UUTs and logging the device logs during experiments. A remote user interface for network configuration, experiment monitoring and data retrieval is available. This user interface can automatically map a given topology to available hardware. Certain environment profiles can be either generated or re-used to allow testing UUTs under different scenarios.

Advantages

Advantages of conducting wireless experiments on ASSERT:

  • Cheaper
  • Less time consuming
  • Mobility and distance
  • Shielded from weather
  • Concurrently run multiple experiments
  • Concurrent support of heterogeneous units under test
  • Eliminates need for user license to conduct experiments in licensed frequency bands
