a.

Storage of packets

b.

Authentication

c.

Encryption

d.

Data recovery

Posted under Cognitive Radio

Answer: (a).Storage of packets Explanation:Connection management in spectrum mobility enforces protocols with respect to the application for maintaining communication. FTP requires protocols to store packets that are transmitted during handoff. But real-time applications do not require storage of packets as the information is obsolete for the corresponding application.
