a.

Network based ontology

b.

Very large scale integrated circuits

c.

Radio propagation simulation tools

d.

Geographical information system

Posted under Cognitive Radio

Answer: (c).Radio propagation simulation tools Explanation:Radio propagation simulation tools are used to predict important parameters such as path loss, signal to noise ratio, and geographical environment information. Location specific radio propagation techniques with 3 D terrain maps offer accurate predictions that can provide better system planning and management.
