The CRSN used to solve the traffic in ISM band, when it used the oppertunstic channel , is this channel is also in ISM band but in another channel in it? Or used the underutlize license channel?
Dear Hadeel,
welcome,
The wireless sensor networks wsn use exclusively the ISM band. Since the applications on this band increase then it needs management of its resources. This is accomplished by the use of cognitive radio as it allow the optimum utilization of the available frequencies.

To shortly answer your question, I will say yes and I will refer you to the following publication : A Framework for Cognitive Radio Wireless Sensor

CRSN till now uses unlicensed ISM bands. With the success of the opportunistic spectrum sensing methods, the CRSN will definitely go for other parts of RF spectrum.
