Question

Which among the following is used to represent interdependencies in cognitive radio?

(a) Representation language

(b) Constraint language

(c) Ontology language

(d) Modelling language

The question was posed to me in an online quiz.

This key question is from Building CRA on SDR Architecture in portion Cognitive Radio Architecture of Cognitive Radio

Answer 1

The correct answer is:

(c) Ontology language

In the context of Cognitive Radio (CR), ontology language is used to represent and describe the interdependencies between various components, actions, and knowledge in a formal way. Ontology in cognitive radio systems helps to capture the relationships and constraints between different entities (such as spectrum usage, channels, and devices) in a way that allows for reasoning and decision-making. This is critical for Cognitive Radio Architecture (CRA), where the system must be aware of the environment and adapt based on the interdependencies of various factors.

• Representation language: Refers to general languages for expressing knowledge, but doesn't specifically capture interdependencies.
• Constraint language: Focuses more on defining restrictions or limitations, rather than relationships or interdependencies.
• Modelling language: Is used to describe system models, but ontology language is more specific to capturing the semantic interrelations.

Therefore, Ontology language is the correct answer.
