1.	Which among the following should be adapted in spectrum mobility management?(a) Single-layer approach(b) Double layer approach(c) Cross-layer approach(d) Alternate layer approachThe question was posed to me in class test.The above asked question is from Next Generation Wireless Network in division Next Generation Wireless Network of Cognitive Radio
Answer» Right option is (c) Cross-layer approach For explanation: Spectrum handoff depends on the spectrum environment as well as the application requirements. By choosing a cross-layer approach, the OPERATIONAL overhead among the functionalities is reduced. This INCREASES the SWITCHING TIME.
