Abstract:

Wireless Sensor Networks (WSNs) are networks formed by

highly constrained devices that communicate measured environmental

data using low-power wireless transmissions. The increase of spectrum

utilization in non-licensed bands along with the reduced power used by

these nodes is expected to cause high interference problems in WSNs.

Therefore, the design of new dynamic spectrum access techniques

specifically tailored to these networks plays an important role for

their future development. In this talk the main challenges of dynamic

spectrum access in WSNs will be described and a first approach to

coordinate sensor nodes will be presented.
