Ubiquitous sensor network (USN) and Radio frequency identification (RFID) are
new technologies which did not have wide practical implementation before 2005.
The concepts of u-society, u-network, u-city and others have been formulated in
support of the world wide perspective for USN and RFID technology.
The USN is a self-organizing network without a stable architecture. Sensor
nodes may be connected to the NGN through the gateway, which converts the ZigBee
protocol, a special protocol for USN, to TCP/IP. The number of sensor nodes in
one USN could be more than 10 000 units and all of these would connect to the
gateway by multi-hop from one sensor node to another in accordance with the best
The self-organizing USN structure can use clustering for route optimization,
and clustering also adds stability to the architecture.
As we see, if we want to test USN in a model network the architecture problem
needs to be solved. Moreover in accordance with self-organizing nature of the
USN a completely new test methodology will be needed.
In contrast, the RFID-network has a very simple network structure. But in
consequence of the rapid world wide implementation of these networks, RFID test
methodology will be needed too.
Study items to be considered include, but are not limited to:
- What is the architecture of the model network for testing USN and RFID?
- What types of USN and RFID could be tested on the model network?
- What types of tests are needed for USN and RFID network components?
- What are the testing scenarios for USN and RFID tests on the model network?
Tasks include, but are not limited to:
- Determination of the architecture for model network part for testing USN
and RFID network components.
- Determination of the USN and RFID network component types for testing on the
- Determination of the types of tests for USN and RFID for testing on the model
- Development of the methodology for testing USN and RFID on the model network.
