Central entity is used to lease the spectrum

b.

Sophisticated spectrum sharing algorithms are used to allocate the spectrum

c.

Distributed communication

d.

Reduced communication overhead

Posted under Cognitive Radio

Answer: (a).Central entity is used to lease the spectrum Explanation:The dynamic spectrum access protocol (DSAP) is a centralized protocol where a central entity is used for leasing spectrum to users in a limited geographical area. DSAP consists of clients, DSAP server, and relay for relaying information between the server and the clients that are not in the direct range of the server.
