1.	Which among the following is not considered for associating a cognitive radio user to an unused spectrum band?(a) Time-varying radio environment(b) Bandwidth(c) QoS requirement(d) Application policiesThe question was posed to me by my college director while I was bunking the class.My doubt stems from Next Generation Wireless Network in portion Next Generation Wireless Network of Cognitive Radio
Answer» The correct option is (d) Application policies Easy EXPLANATION: The various CHARACTERISTICS of the unused spectrum bands determined during spectrum SENSING depend on the time-varying radio environment, operating FREQUENCY, bandwidth, and quality of service requirements of the cognitive radio user. Spectrum management is required to correctly associate a user to a compatible spectrum band AMONG all available spectrum bands in xG networks.
