Elektronikas un datorzinātņu institūta (EDI) (eng.: Institute of Electronics and Computer Science) TestBed or in short EDI TestBed is a 100+ node heterogeneous sensor network and wireless network testbed for validation and research in sensor network & wireless network protocols. In  addition, it also includes a sub-project for intelligent transportation system testing using the new IEEE 802.11p standard.

Motivation

Development of Wireless Sensor Networks is a challenging task, especially when it comes to large numbers (10+) of sensor nodes. WSN designers must take special care of hardware and software and perform many tests before running their applications in real life.

To evaluate the performance of WSN adequately, the developer should perform:

• energy consumption monitoring;
• battery discharge simulations;
• radio communication stability monitoring.

Our EDI TestBed provides realistic environment and simplified testing procedure for embedded systems, especially for WSN.

EDI TestBed capabilities

• IEEE 802.11a/b/g/n/p protocol testing;
• IEEE 802.15.4 protocol testing;
• Fully reconfigurable routers (OS and other software can be setup for each test individually) with XM1000, TelosB-compatible wireless sensor nodes attached.
• Energy measuring and remote debugging capabilities for the sensor nodes through a custom adapter
• Control and management through either OMF (ruby scripts) or, alternatively, a simple web-based interface
